a. Farmer Brown has a breed of white-feathered chickens that is homozygous for the dominant allele A which produces coloured feathers. These chickens are also homozygous for the dominant allele B for another independently assorting gene which inhibits colouration of the feathers. Farmer MacDonald has a different breed of white chickens that are homozygous recessive for both the A/a and B/b genes. One of farmer Brown's hens (AABB) is crossed with one of farmer MacDonald's roosters (aabb) to generate the F1 generation. What are the expected F2 phenotypes and proportions from the crossing the F₁ offspring?

A. Four babies are born in a hospital and are mixed up. Based on the blood type and hairline, match the baby to its parents. Type A blood and Type B blood are codominant and type O is recessive. Widow's peak is dominant to a straight hairline. Each baby has the following phenotypes: Baby A = B blood, widows peak Baby B = B blood, straight hairline Baby C=AB blood, straight hairline Baby D = O blood, straight hairline The phenotypes of the parents are as follows: Ms. Smith: A blood, widows peak Mr. Smith: B blood, straight hairline Ms. Jones: O blood, widows peak Mr. Jones: O blood, widows peak Ms. Black: AB blood, widows peak Mr. Black: O blood, straight hairline Ms. Green: B blood, straight hairline Mr. Green: B blood, straight hairline which the The parent cell b
B. Labrador retrievers have 3 varieties of fur colour: yellow, chocolate or black. Two genes are involved, each with a dominant (Y and B) and a recessive allele (y and b). The allele Y codes for the ability to produce hair pigment: Yy and YY dogs have dark pigmented fur but all yx, individuals are lighter coloured and yellow. The B allele codes for the ability to make hair with the darkest colouration: BB and Bb individuals have black fur, bb dogs have a lighter shade which is chocolate.

7) Skin color is a complex trait and while just a few genes account for the major difference between light and dark skin color, dozens of other genes participate. Assume in this hypothetical scenario there are only two genes for skin color, A and B. Each gene exhibits incomplete dominance. AABB (homozygous dominant for both genes) results in the darkest skin color and aabb (homozygous recessive for both genes) results in the lightest skin color. Tomas is heterozygous for both genes; his partner, Helga, is heterozygous for the A gene and homozygous recessive for the B gene. Construct a Punnett Square showing the cross of this couple. What are the expected genotypes and phenotypes of the children this couple could have?
Part B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…
