Explanation:
Detailed explanation-1: -The allele that is hidden (or suppressed) in a heterozygote is said to be recessive. We usually use a lower case letter to indicate recessiveness (b). A heterozygous calf has one red allele and one black allele (Bb). These animals are always black.
Detailed explanation-2: -When writing a genotype, the dominant allele is usually represented by a capital letter, while the recessive allele has a lowercase letter.
Detailed explanation-3: -A capital letter is used to represent the dominant form of an allele or gene, and a lower case letter is used to represent the recessive form of the allele.
