Question 1
If black fur color is controlled by a dominant allele (
B) and brown by its recessive allele (
b), give the genotypes of the parents and offspring of a cross of a black male with a brown female that produces 1/2 black offspring and 1/2 brown offspring.
Question 2
If long or round are homozygous forms of an incompletely dominant gene and oval is the phenotype of the heterozygote, give the
F2 ratio of the cross between long and round (both genotype and phenotype).
