Another Punnett square that shows a cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr). Determine the ratios of the genotypes and phenotypes for hair color resulting from this cross

Here is a Punnett square that shows a cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr).

Since the phenotype is unknown, we could say it's short (RR) (Rr) and long (rr)

Since it's mixed, we could say that the ratio is 3/1
