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

The proportions of genotype and phenotype for this cross are:

50% Rr = color color determined by the dominant (red) allele.

25% RR = Color coloring determined by the dominant allele (red).

25% rr = Coloration of the color determined by the recessive allele.

Explanation:

As you can see in the image attached below, the cross between a red ox (Rr) and a red cow (Rr) would result in an offspring composed of 50% of individuals with the Rr alleles, 25% of individuals with the RR alleles and 25% of individuals with the rr allele.

As the ox and cow that are the parents are red, we can confirm that this is the phenotype presented by the dominant allele. This is because heterozygous individuals, such as the progenitors of that crossing, present the phenotype determined by the dominant allele, since the recessive alleles are inhibited when together with a dominant allele.

For this reason, we can say that within the offspring, those individuals with the "RR" and "Rr" alleles will have a red color, which is shown by the dominant allele. Individuals who have the "rr" alleles, on the other hand, will have the color determined by the recessive allele.
