The answer is d. carry on metabolism.
Metabolism includes all chemical reactions involved in maintaining order within cells and organs. The purpose of metabolism is a conversion of food or fuel to building blocks for macromolecules and to energy for cellular processes. It is involved in the elimination of waste, too. Regulation of metabolism is important for normal functioning of cells and organs.
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
Reproductive isolation must happen
