Identical twins are produced from the same sperm and egg (which splits after the first mitotic division), whereas fraternal twins are produced from separate sperm and separate egg cells. If two parents, one with brown eyes (a dominant trait) and the other with blue eyes (the recessive trait) produce one twin boy with blue eyes, what is the probability that a fraternal twin will transmit the blue eye allele to his or her offspring
Answer:
This is 25%
Explanation:
Analysis, Since the dominant brown eyed parents produce blue eye child, this shows they are heterozygote dominant
However,this fraternal twin is not genetically identical, due to the blue eye color,(recessive) but the fact remain that they are the parents.(because he inherited the recessive allele from each of the parent)Therefore the probability is 25%.
This is because he is the only one out of the 4 kids( based on Mendelian fashion) this is 1/4,25%
Fraternal tweens are produced from different maternal and paternal gametes. The blue-eyed tween has 100% probability of transmitting the blue-eyes allele to the offspring, while the brown-eyed tween has 50% probability.
Available data:Fraternal twins are produced from separate sperm and separate egg cells.Brown eyes ⇒ Dominant traitBlue eyes ⇒ Recessive traitWe will name B to the dominant allele that codes for brown, and b to the recessive allele that codes for blue eyes.
So, the possible genotypes and phenotypes are
Gentoype Phenotype
BB Brown eyes
Bb Brown eyes
bb Blue eyes
Solving the problemThe parent with blue eyes must be only bbThe parent with brown eyes must be either BB or BbFor the twin boy to have blue eyes, he must have received two recessive alleles, one from the mother and one from the father.
So the father is heter0zyg0us for brown eyes, Bb.
Cross: Bb x bb
F1) 1/2 of the progeny is expected to be brown-eyed, Bb
1/2 of the progeny is expected to be blue-eyed, bb.
So we have two genotypes for the tweens, Bb and bb.
bbThe bb tween has blue eyes and is h0m0zyg0us recessive for the trait. So the probability that this fraternal twin will transmit the blue eye allele to his or her offspring is 100% This tween can only provide recessive alleles to his or her progeny. BbThe Bb tween has brown eyes and is heter0zyg0us for the trait. So the probability that this fraternal twin will transmit the blue eye allele to his or her offspring is 50% This tween can provide one dominant or one recessive allele to his or her progeny.So, the blue-eyed tween has 100% probability of transmitting the blue-eyes allele to the offspring. The brown-eyed tween has 50% probability of transmitting the same allele to the descendants.

A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N. If both children are of blood type M, list all of the possible parental phenotypes
Answer:type A
Explanation:
Possible parental phenotypes could be mother with blood type A Rh positive and MN or MM while the father will have blood type B Rh negative and MN or MM type.
What is blood typing in humans?Blood typing is a method to tell what type of blood group or blood an individual has. Blood typing is done so a person can safely donate hos or her blood or receive a blood transfusion from another person. It is also done to see if a person have a substance called as the Rh factor on the surface of the red blood cells.
Blood typing in humans is an example of codominance and multiple allelism. Blood group A and B are codominant and O is recessive allele. Rh negative is recessive over Rh positive blood group. A third gene for the MN blood group is codominant, in which M and N are codominant.
In the given question, both the children are of blood type M. In this case, M and N are codominant over each. Therefore, the possible parental combinations can be MN × MN or MM × MN.

what is the importance of mastication during digestion
Mastication is the process by which food is crushed and ground by teeth. It increases the surface area of foods to allow a more efficient break down by enzymes.
Many traditional household appliances, including clothes dryers, use an
excessive amount of electricity. One solution is to replace older appliances
with modern appliances that are more energy-efficient.
Which of the following behaviors could further refine this solution?
OA. Use the energy-efficient appliances instead of more conservative
tactics.
B. Use additional conservation tactics, like sometimes hanging
clothes outside to dry.
OC. Use energy-efficient appliances and traditional appliances at the
same time.
OD. Use the energy-efficient appliances more often than you need to.
Answer:
B. Use additional conservation tactics, like sometimes hanging
clothes outside to dry.
Explanation:
Ap3x
Using extra energy-saving techniques, such as occasionally hanging clothes outside to dry them, could improve the solution of replacing outdated equipment with newer, more energy-efficient appliances. So, the correct option is B.
What are energy-saving techniques?Energy-saving technology, commonly referred to as green technology, is innovation that enhances upon or replaces current systems in order to save energy. Technology of this kind often helps operators save money while reducing the negative effects of human interference with the environment.
Instead of leaving appliances on standby, turn off the power source to conserve the maximum energy. As you leave the house or go to bed, turn off the heater, air conditioner, and other equipment. Turn off the computer and any other devices, including printers and Wi-Fi routers, at night or while we're away.
Using extra energy-saving techniques, such as occasionally hanging clothes outside to dry them, could improve the solution of replacing outdated equipment with newer, more energy-efficient appliances.
Therefore, the correct option is B.

Which of the following is not a method of heat transfer? Conduction Insulation Radiation Convection
Answer:
insulation is the correct answer
The method that is not one of the heat transfer method is insulation.
Heat transfer can be regarded a term in thermal engineering use to describe the generation as well as the use and conversion, exchange of thermal energy that exist between physical systems. Heat transfer can be done with different mechanismsThese are: conductionconvectionRadiationConvection can be regarded as the flow of heat in fluids, these fluids could be warmed gas, water.Conduction can be regarded as the movement of heat through objects that are in physical contact, like two metalsRadiation can be regarded as the energy which appears from a source then travels through space, this do contain wave-like properties. Insulation can be regarded as setting up a barrier between two objects, usually between hot and the cold object , so that heat reduction can be achieved.Therefore, Insulation is not heat transfer mechanism, it i a way to reduce heat loss.

Why is a supply of oxygen important for muscle contraction?
Answer:
For muscle contraction to take place oxygen is needed. ... Oxygen allows the body to convert glucose into ATP more efficiently without creating a waste product.
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. ... Whether you're exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP
