in drosophila melanogaster, the common fruit fly, curved wings "I" and purple eyes "r" are two linked recessive genes found on chromosomes 2. The dominant wild type alleles for those genes are long wings"L" and red eyes "R"
a)describe the expected ratio of offspring in the f2 generation of these genes were located on different chromosomes
b)the results in the f2 generation of these flies were: 40 long winged, red eyes; 40 curved winged, red eyes; 10 long winged, purple eyes, and 10 curved winged, red eyed. how many map units apart are the genes for curved wings and purple eye color?
Answers
Answer:
the other person is right, he had messed up before saying that 60 x 40 = 100, but 60 + 40 = 100. Then I had told him that his answer was wrong and that he should put the answer as 240 instead since 60 x 40 = 240 and not 100.
Explanation:
The expected ratio of offspring in the f2 generation of these genes were located on different chromosomes is 25%
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division.
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children with type o. what blood type should he request on his dating survey? what must Opine’s blood type be in order to produce offspring with type O blood?
Answers
Answer:
He should request type O on his dating survey.
Opine's blood type must be AO to have a higher probability of producing O offsprings.
Explanation:
O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.
O blood type results are possible thanks to OO genotypes.
If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.
As regards the mother, her blood type should be OO.
We can see this more clearly in Punnet Square.
║ A ║O
O║AO║OO
O║AO║OO
There is a 50% of probability of having O offsprings with AO and OO.
║ A ║A
O║AO║AO
O║AO║AO
With AA and OO, the probability is 0%
║ A ║O
A║AA║AO
O║AO║OO
With both parents having AO, blood the probability of having a OO offspring is 25%.
In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.
Eye color in a particular strain of fly is influenced by one gene with two alleles: a dominant allele that results in red eyes and a recessive allele that results in sepia eyes. A red-eyed female from a true-breeding population is mated with a sepia-eyed male. The Fl offspring are all red-eyed. The Fl flies are allowed to interbreed, producing the following in the F2 generation.
Females: 40 red eyes; 13 sepia eyes
Males: 39 red eyes; 11 sepia eyes
Which of the following best describes the likely mode of inheritance for the eye-color gene?
a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.
c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.
d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.
Answers
Answer:
The correct option is a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
Explanation:
Available data:
Eye color is influenced by a diallelic gene R dominant allele results in red eyesr recessive allele results in sepia eyesCross: true-breeding red-eyed female with a sepia-eyed maleF1: 100% red-eyed.F2: Females: 40 red eyes; 13 sepia eyesMales: 39 red eyes; 11 sepia eyes
77% of the total progeny has red eyes and 23% has sepia eyes.
Among females, 75% is red-eyed, and 25% is sepia-eyed
Among males, 78% is red-eyed, and 22% is sepia-eyed.
The general phenotypic ratio is 3:1
If the eye-color gene was sex-linked, the phenotypic ratios would be different. There would be a higher proportion of red-eyed females than red-eyed males. Females would only express red eyes, while males would express red and sepia eyes. This is
Cross: X⁺X⁻ x X⁺Y (Note: The symbol + represents the allele R
Phenotype: red-eyed both and the symbol - the allele r)
Gametes) X⁺ X⁻ X⁺ Y
Punnett square) X⁺ X⁻
X⁺ X⁺X⁺ X⁺X⁻
Y X⁺Y X⁻Y
F2) 3/4 of the whole progeny would be red-eyed
1/4 of the whole progeny would be sepia-eyed
BUT
Females: 100% red-eyed
Males: 50% red-eyed and 50% sepia-eyed
These proportions are not coincident with the exposed real proportions
So,
c. The eye-color gene is likely sex-linked because the males and females have similar phenotype ratios.
If this gene was sex-linked, Males and females would not have similar phenotype ratios. This is FALSE.
d. The eye-color gene is likely sex-linked because the males and females display both phenotypes.
If this gene was sex-linked, Males would display both phenotypes, but females would only be red-eyed. This is also FALSE.
According to this, we can assume that this is an autosomal gene. If this is true, then
Cross: Rr XX x Rr XY
Gametes) RX, RX, rX, rX
RX, RY, rX, rY
Punnett square:
RX RX rX rX
RX RRXX RRXX RrXX RrXX
rX RrXX RrXX rrXX rrXX
RY RRXY RRXY RrXY RrXY
rY RrXY RrXY rrXY rrXY
F2) From the whole progeny
12/16 = 3/4 = 75% would be red-eyed 4/16 = 1/4 = 25% would be sepia-eyedPhenotypic ratio 3:1
Among females
6/8 = 3/4 = 75% would be red-eyed, R-XX 2/8 = 1/4 = 25% would be sepia-eyed, rrXXPhenotypic ratio 3:1
Among males
6/8 = 3/4 = 75% would be red-eyed, R-XY 2/8 = 1/4 = 25% would be sepia-eyed, rrXYPhenotypic ratio 3:1
The phenotypic ratio in all cases are 3:1.
b. The eye-color gene is likely autosomal because more females have sepia eyes than males do.
Both males and females exhibit sepia eyes in equal proportions. This is FALSE
a. The eye-color gene is likely autosomal because males and females have similar phenotype ratios.
Males and females do have similar phenotype proportions of red eyes and sepia eyes. This is TRUE

Answers
The cell multiplies and creates a copy of its DNA during interphase. In the mitotic (M) phase, the cell divides into two new cells by dividing its cytoplasm and DNA into two sets.
What is the main role of interphase stage of cell cycle?A cell consumes the bulk of its time in what is known as interphase, where it creates, duplicates its chromosomes, and acquires available to split. The cell then moves interphase, goes direct mitosis, and completes dividing.
The cell multiplies and the nuclear DNA is duplicated during interphase. The mitotic phase immediately follows interphase.
Chromosomes that have been duplicated are separated and distributed across daughter nuclei during the mitotic phase. Usually, the cytoplasm is divided as well, producing two daughter cells.

Answers
The statement which is true about cell respiration is; Choice B: Glycolysis splits sugar to produce pyruvate and FADH2-
Definition of terms:
Cellular respiration is a process used by all living organisms to convert glucose into energy.
Cellular respiration is a collection of three unique metabolic pathways: glycolysis, pyruvate oxidation, the citric acid cycle, and the electron transport chain.
Glycolysis; This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecule. A process which releases FADH2- in the process.Pyruvate Oxidation: In eukaryotic cells, the mitochondria is the site of pyruvate oxidation. The release of CO2 is a characteristic of this step.The Electron transport chain: The electron transport chain is the final component of aerobic respiration and is the only portion of glucose metabolism that uses atmospheric oxygen.Electrons are rapidly transferred from one component to the next to the endpoint of the chain, where the electrons reduce molecular oxygen, O2 producing water in the process.
