Two cows are living on a ranch. One cow is much larger and more muscular than the other.Which of the following best describes a genetic factor that could have led to the cows’ different traits?Choose 1 answer:Choose 1 answer:(Choice A)   The larger cow has access to more food than the smaller cow does.AThe larger cow has access to more food than the smaller cow does.(Choice B, Checked)   The smaller cow has brown patches on its fur, and the larger cow has black patches.BThe smaller cow has brown patches on its fur, and the larger cow has black patches.(Choice C)   The cows are different breeds, so they have different genes affecting their growth.CThe cows are different breeds, so they have different genes affecting their growth.

In a population of cows, some individuals have a black coat and others have a red coat. The gene for coat color has two possible alleles. One allele is for a black coat (B), and the other allele is for a red coat (b).A certain cow in the population has the genotype bb for the coat color trait.Which term best describes this cow’s genotype?Choose 1 answer:Choose 1 answer:(Choice A)   homozygousAhomozygous(Choice B)   heterozygousBheterozygous

You are studying the phenotypic traits of bone density and muscle mass in cattle and find that the two traits have a correlation coefficient of +0.97. What is the interpretation of this statistic?Group of answer choicescattle with higher bone density tend to have lower muscle masscattle with higher bone density tend to have larger muscle massthere is no relationship between bone density and muscle massthe two traits are controlled by the same genes

Fur color in mice is affected by a gene with two alleles. The B allele causes dark brown fur and is completely dominant over the b allele that causes light brown fur. What is the fur color of a mouse with the genotype Bb?Multiple choice question.Light brown furVery dark brown fur due to two different alleles being presentDark brown furA mixture of dark brown and light brown fur
