n a container/tub, place 50 pieces ofred paper, 50 pieces of pink paper, and50 pieces of white paper. Let usassume that each color is thephenotypic expression of thegenotypes homozygous dominant AA(red), heterozygous Aa (pink), andhomozygous recessive aa (white).Without looking, randomly pick 20 pieces of paper from your container/tub and assumethat those individuals died upon picking, thus will be removed from your population. a. If you are a picky eater and prefer the white only, what do you think will happen in the genotypic frequency and allelic frequencies of the red, pink and white pieces of papers?
What do you know about individual III-1's mother? II II IV O Shehad the trait. She was a carrier. She was homozygous recessive. She was homozygous dominant.
Attached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.
A woman who is heterozygous, Bb, has brown eyes; B (brown) isthe dominant allele, and b (blue) is recessive. One of her eyes,however, has a patch of blue color. Give three different explanationsfor how this might have occurred?

Having a widows peak is dominant W to not having one (ww)Having attached earlobes is a recessive trait (ee)- Jack and Jill are heterozygous for both traits.What's the probability of them having a child with a widow's peak and attachedearlobes?
In individuals affected by cystic fibrosis, salt crystals may appear afterperspiration dries up. In addition, the disease causes respiratory disorderswhich can be both debilitating and lethal. It occurs in individuals homozygousfor recessive gene. If 2 normal parents had a daughter with the symptoms ofthis disease, and a normal son, what is the probability that he might be acarrier of the recessive gene?Express answer in fraction form.
In a dihybrid cross of two heterozygous individuals, you expect a 9:3:3:1 phenotypic ratio in the offspring, but observe a ratio of 9:7. What is the most likely explanation? O Codominance O It is a sex-limited trait O Simple Mendelian inheritance O Incomplete penetrance O Epistatic interaction of the two genes

Albino rabbits (lacking pigment) are homozygous forthe recessive c allele (C allows pigment formation).Rabbits homozygous for the recessive b allele makebrown pigment, while those with at least one copy ofB make black pigment. True-breeding brown rabbitswere crossed to albinos, which were also BB. F1 rabbits, which were all black, were crossed to the doublerecessive (bb cc). The progeny obtained were 34black, 66 brown, and 100 albino.a. What phenotypic proportions would have beenexpected if the b and c loci were unlinked?b. How far apart are the two loci?
