Which type of traits vary quantitatively due to the interaction of multiple genes? polygenic codominant incomplete dominant dominantIf a red cow (homozygous dominant) is crossed with a white cow (homozygous dominant), what alleles will the offspring have? Rw RW rW rw

1. Polygenic

2. RW

Explanation:

1. A polygenic trait is regulated by more than one gene. The phenotype of the organism is regulated by sum total of all the dominant alleles of these genes. Therefore, these traits exhibit continuous variations and are called quantitative traits. Skin color in humans is an example as it is regulated by more than one genes and the phenotype is determined by total dominant alleles of these genes.

2. If allele R gives red phenotype and the W gives white phenotype, a cross between RR (red) and WW (white) would produce all the cows with RW genotype. The parent cow with RR genotype would form all the gametes with R allele while all the gametes from WW parent would have one copy of the W allele. The random fusion of gametes with R and W alleles would produce progeny with RW genotype.

who knows

explanation:

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
