This is a simple heterzygous cross, each parent having gametes with A and a.
In a species of snakes, two parents of genotype Aa are crossed together (Aa x Aa). The locus is not sex-linked.
Assume complete dominance of the alleles, with AA and Aa causing a jagged scale pattern, and aa causing a smooth scale phenotype.
Give the expected genotypic and phenotypic frequencies of the offspring.
