Practice Question

For the pedigree shown below, list all of the possible genotypes of individuals 1-7 and indicate the probabilities of each genotype.

For the pedigree shown below, list all of the possible genotypes of Kid 1 and their probabilities.

For each genotype of Kid 1, list the probabilities of different genotypes for Kid 2.

A and a are alternative alleles for an autosomal gene.

What are the probabilities that none of individuals 3,4,5 and 6 have the a allele. What about all of them?

Consider two loci: #1 with alleles A and a, and #2 with alleles B and b

What are all the possible genotypes for Kid and their probabilities if.

a) locus 1 and locus 2 are on different chromosomes

b) locus 1 and locus 2 are on 10 Mb apart on a 100 Mb chromosome

c) locus 1 and locus 2 are on 10 Mb apart on a 200 Mb chromosome
