A formerly large, random-mating population switches to a high rate of inbreeding. As a consequence: a. Recessive, deleterious traits are more evident in the population. b. Migration rates will decrease. c. Dominant traits will be selected against. d. Genetic drift will be stronger. e. Heterozygotes become more common.
Answers
Answer: The correct option is A.
Explanation:
This is because inbreeding is the mating or organisms that are genetically related in one way or the other and it go against interchanging of DNA. This normally result in recessive traits in a population and bring about the same traits.Therefore there is more possession of two identical traits in the population and there is decrease in genetic variation because of the similar traits in offsprings genome.
The consequence of moving from random-mating population to a high rate of inbreeding is a. Recessive, deleterious traits are more evident in the population.
This is because in inbreeding, individuals are further decreasing genetic variation as a result of increasing h. zygosity in the genomes of their offspring.
Random mating on other hand, the mattings in a population is as a result of proportion to their genotypic frequencies.

Which is not a reason why organisms are classified into Domains and Kingdoms?
Answers
Answer:
for a better study of organisms
Explanation:
Organisms are classified into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.
Domains and kingdoms are the highest categories of classification. It is usually used to classify organisms to make it simple for their identification. It is not classified only to study the organism better.
What are domain and kingdom?A domain is the highest category of classification and a kingdom is a second-highest category.
Living things are placed in these categories according to their way of obtaining food, the number of cells, types of nuclei, etc.
It is used to avoid confusion between the organism and to show that the organisms are related to each other.
Thus, it can be concluded that it is not used not only study but for other purpose also.

A group of scientists were using CRISPR to treat a mouse with cystic fibrosis, a disease caused by a defective Cl- channel protein called CFTR. The most common cause of cystic fibrosis in humans is the absence of a phenylalanine, an amino acid, in the CFTR protein, which prevents CFTR from achieving the correct 3-D structure.If the scientists wished to repair this mutation, how would they alter the mutated CFTR gene before using CRISPR to insert the DNA into the mice
Answers
Answer:
they can insert the codon that encodes phenylalanine by CRISPR-Cas mediated homology-directed repair
Explanation:
The CRISPR (clustered regularly interspaced short palindromic repeats,)-Cas (CRISPR-associated protein) is a versatile technology for genome editing which has been developed by adapting a natural defense mechanism found in prokaryotic organisms. The CRISPR-Cas genome editing tool can be used to edit DNA sequences in eukaryotic genomes (for example, in human genomes) and thus restore gene function (in this case, the CFTR gene function). The system consists of a Cas protein that cleaves the DNA at specific genomic sites and a single guide RNA (sgRNA) that guides the Cas protein at specific genomic locations. CRISPR-Cas mediated homology-directed repair refers to the process where Cas cuts the DNA to triggers the homologous recombination (HR) DNA repair pathway, by which it is possible to insert new genetic sequences at specific genomic sites (in this case, the codon that encodes phenylalanine within the specific CFTR gene).
Why is the sequence of amino acids important to protein function?
A)
The sequence of amino acids doesn't have an effect.
B)
Amino acids can only be combined in a specific order, otherwise the bonds will fall apart.
C)
The order of amino acids determines the shape a protein will take.
D)
The order of the amino acids can be read like a code to assemble DNA.
Answers
The order of amino acids determines the shape a protein will take. The correct option is C.
What is amino acid?Organic compounds that contain both amino and carboxylic acid functional groups are known as amino acids.
Although hundreds of amino acids exist in nature, the alpha-amino acids that comprise proteins are by far the most common. The genetic code contains only 22 alpha amino acids.
Amino acids, also known as protein building blocks, are compounds that play a variety of important roles in your body.
They are required for vital processes such as the synthesis of proteins, hormones, and neurotransmitters. Protein-rich foods, such as meat, fish, and soybeans, are high in amino acids.
Each protein's unique 3-dimensional structure and function are determined by the sequence of amino acids.
The sequence of genes determines the combinations of three DNA building blocks which is nucleotides that basically code for amino acids.
Thus, the correct option is C as it is assemble in such a way to determine the shape of protein.

What form of reproduction is shown?
Answers
Answer:
Asexual (vegetative) reproduction
Explanation:
Asexual reproduction is a type of reproduction that involves only a single parent. As opposed to sexual reproduction, it does not involve the formation of sex cells or gametes.
According to this question, Bryophyllum, which is a plant known to propagate itself via its leaves is practicing a form of asexual reproduction called VEGETATIVE PROPAGATION, which is the propagation of a plant via its vegetative parts e.g. stems, leaves, cuttings etc.

In drosophila, red eyes is the wild-type phenotype. Several different genes (with each gene existing in two or more alleles) are known to affect eye color. One allele causes purple eyes, and a different allele causes sepia eyes. Both of these alleles are recessive to red eye color. When flies with purple eyes were crossed to flies with sepia eyes, all the F_1 offspring had red eyes. When the F_1 offspring were allowed to mate with each other, the following data were obtained:
146 purple eyes
151 sepia eyes
50 purplish sepia eyes
444 red eyes
