Lifesci 4 - lecture 4 - assortment and meiosis. A human pedigree and the abo blood types of some of the members of the family are shown. Ia from iii-2] x p[ from ii-2] x p[ Ia from i-2] = x x = from iii-2] = x = 1/16. There are 4 different alleles for the coat color gene. The colors of guinea pigs homozygous for these various alleles are shown. Individual 6 and 7 are sepia and it must come from individual 2 since dad is cream and it cannot have allele ( Individual 2 is black, which means the allele must be c_, and based on the previous point, genotype = cck. )ck: brother and sister 6 and 7 are mated. Albino is recessive to everything else, must have genotype ( ) since its phenotype is cream and it has to have an albino. )cck a ck ccd a genotype ( allele to pass on.
