In a breeding experiment, the male parent is known to have either two dominant genes (symbolized by AA) or one dominant and one recessive (Aa). These two cases are equally likely. The female parent is known to have two recessive genes (aa). Since the offspring gets one gene from each parent, it will be either Aa or aa. [If the male parent is Aa, it is equally likely for the offspring to get A or a from him]
a. If we suppose one offspring is Aa, what is the probability that the male parent is AA?
b. If we suppose two offspring are both Aa, what is the probability that the male parent is
AA?
c. If one offspring is aa, what is the probability that the male parent is Aa?

Consider a population of individuals each of whom possesses two genes which can be either type A or type a. Suppose that in outward appearance type A is dominant and type a is recessive. (That is, an individual will have only the outward characteristics of the recessive gene if it is aa.) Suppose that the population has stabilized, and the percentages of individuals having respective gene pairs AA, aa, and Aa are p,q, and r. Call an individual dominant or...

3. In fruit flies, two genes S and T have similar function. If either, or both of the genes have at least one dominant allele present, the flies have normal wings. If not, then the wings are small. Two SsTt flies are crossed together. Assuming that the two genes assort independently, what are the expected phenotypes, and their ratios, in their offspring? 8. A male carries a recessive mutation on the X chromosome that causes hemophilia, a blood clotting disorder....

Part A, In humans, pointed eyebrows are dominant to smooth eyebrows and widow’s peak is dominant to continuous hairline. What phenotypic results would you expect in the offspring from a cross between an individual heterozygous for both genes and an individual homozygous dominant for both genes? Show work. Doesn't matter what letter is used, just clarify Part B. Cystic fibrosis is an autosomal recessive disorder and you should consider it exceedingly rare. A man and woman are planning on having...

You are doing a genetics experiment with fruit flies. In your first cross, you cross two true-breeding flies (P generation). The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. In the following questions, please indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are not found...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...

1) One parent has yellow flowers, which is the dominant allele Y. The second parent has white flowers, the recessive allele y. If the offspring are all yellow, what is the genotype of each parent? 2) A plant is homozygous for the recessive gene "a" causing the plant to be short. What is the genotype and the phenotype of this plant? (In your answer, be very clear about which is the genotype and which is the phenotype). 3) The allele...

Suppose you have a group of beetles. You find that a white eye color in one of the beetles is due to a point mutation. Refer to B and b (where B is the allele associated with the dominant phenotype, and b is the allele associated with the recessive phenotype) in order to answer the following questions: 1) The cross of a pure breeding male with white eyes with a pure breeding female with normal eyes leads to all offspring...

Red hair in humans is recessive, whereas dark hair is dominant, Suppose that a red-haired male and a heterozygous female have a male child who then mates with a heterozygous female. a) What is the probability that the grandchild is pure dark-haired? b) What is the probability that the grandchild is dark-haired? c) What is the probability that the grandchild is red-haired?

Unicorn abilities are determined by two linked genes, the ability to have a rainbow coat (R) is dominant to a white coat (r) and the ability to fly (F) is dominant to the lack (f). If these genes are linked by 15 map units what would be the number of expected offspring of a heterozygous flying rainbow unicorn with a homozygous white non-flying male if we had 300 offspring.
