Detailed explanation-1: -The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
Detailed explanation-2: -Dominant alleles are represented by capital letters and recessive alleles are represented by lowercase letters. For example, blue eyes are a recessive trait and brown eyes are a dominant trait.
Detailed explanation-3: -By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.
