In cattle, codominance of the allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coa
mario62 [17]

Answer:

Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)

Phenotype ratio: 1 Red : 2 Roan : 1 White

Explanation:

Codominance is a kind of inheritance pattern in which both alleles are equally dominant in a gene. This means that both alleles when in a heterozygous state will be simultaneously expressed. According to this question, allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coat (RW) in cattle.

Hence, in a cross between a a roan cow (RW) and a roan bull (RW), the following gametes will be produced: R and W.

Using these gametes in a punnet square (see attached image), the offsprings with the following genotypes will be produced: RR, RW, RW, WW.

Therefore, based on the results of the cross;

Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)

Phenotype ratio: 1 Red : 2 Roan : 1 White

<span>1.    </span>Their genotype. Similarity in DNA between the species is a good indication of their relatedness.

<span>2.    </span>Their phenotype. If the two species have similar body form and function, then there is a good possibility that they are related.

<span>The presence of intermediates, either living or in the fossil record, can show relatedness between two species.</span>
