Answer:
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.

Hey :)
Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.
Hopefully this helped and good luck!!!
Answer:
Answer - 9 : 37
Explanation:
Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene.
<span>The answer is C because fungi use decomposition to get nutrition, while plants produce their own nutrients, making them autotrophs. Answer choice A is incorrect because fungi cells do have cell walls, even though they contain chitin, which isn't present in the cell walls of plants. Answer choice B is incorrect because while they do form colonies, most fungi are multicellular. Answer choice D is incorrect because plants are also able to reproduce both sexually and asexually.</span>
