Jun 22, 2020 | Because she must receive at least one allele from her mother, and one allele from her father, and since both of her mother's alleles are lower-case "s", the daughter rabbit must also have a lower-case "s". at_ Bb CC Dd EE, -Bb: B for dominant (black) and b because he carries chocolate, -CC: Because he does NOT carry White (lowercase c), -Dd: Lowercase d because he carries dilute, -EE: Because he does NOT carry non-extension ('tort'- ee). Imagine we have a mating pair of a male heterozygote black rabbit (Bb) and a female homozygote black rabbit (BB), what will the offspring be? visiting Keio University Hospi-tal between December 1996 and May 1997 were enrolled in this study (152 male, 127 female, age 15 to 87 yr). gB How many out of 16 have grey fur and red eyes?

Fill it out and determine the phenotypes and proportions in the offspring. When talking about colours we use genotypes to identify what genes the rabbit does and does not have. The genotype is often written as YY or yy for which each letter represents one of the two alleles in the genotype. What is the geneotype of a female? The same is true of all other placental mammals males produce X and Y gametes, and females produce only X gametes (Figure 4).
