A lion is heterozygous at two linked autosomal loci (AaBb). The alleles are in coupling phase. If the two genes are 30 cM apart, what gamete types can be produced, and what is the expected proportion of each?
a. AB (25%), ab (25%), Ab (25%), aB (25%)
b. AB (35%), ab (35%), Ab (15%), aB (15%)
c. AB (15%), ab (15%), Ab (35%), aB (35%)
d. AB (15%), ab (35%), Ab (35%), aB (15%)
