1.) Black hair in rabbits is determined by a dominant allele, B, and white hair by homozygosity for a recessive allele, b. Two heterozygous rabbits mate and produce a litter of five offspring. With what frequency would we expect to find: A.) two whites and three black offspring B.) four white and one black offspring. 2.)

Given the following genotypes: QqRRSs x QqrrSs, what is the probability of producing offspring that present only one dominant feature? Show your work. For a sex-linked disorder such as hemophilia, illustrate the punnett square and pedigree for the offspring of an affected male (X Y) and carrier female (X^AX^a). Show your work. What is the probability of having an affected daughter? What is the probability of having a normal male?

Observing the phenotypic ratio of the offspring generation of a mated pair can increase our understanding of inheritance of traits. In wolves, gray fur and yellow eyes are dominant, black fur and blue eyes are recessive, and both traits are governed by simple (complete) dominance In the Ely, MN area there exists an alpha pair: a male dihybrid (double heterozygote) wolf displaying both dominant phenotypes mated with a female wolf recessive for both traits. Researchers hypothesize the two genes (fur...

A simple model for human offspring is that each child is equally likely to be male or female. With this model, a three-child family can be thought of as three random determinations of sex, in order. a. What are the 8 possible outcomes? What is the probability of each? b. What outcomes make up the event “the oldest child is a daughter”? What is the event’s probability? c. What outcomes make up the event “the family has one daughter and...
