Question

suppose that a mouse with black fur has both an allele for black fur and an allele for white fur (bb). based on this information, you can conclude that the dominant allele must be for black fur and the recessive allele must be for white fur. complete for this lab, assume that the allele for black fur is dominant. this allele’s symbol is the allele for white fur is recessiv his allele’s symbol is b b done

Explanation:

Step1: Recall Dominant/Recessive Allele Symbols

In genetics, dominant alleles are typically represented by uppercase letters, and recessive alleles by lowercase letters of the same symbol. Here, black fur is dominant, so its allele symbol should be uppercase. The white fur allele (recessive) should be lowercase.

Step2: Determine Symbols

Given black fur is dominant, its symbol is \( B \) (uppercase). White fur is recessive, so its symbol is \( b \) (lowercase).

Answer:

The allele for black fur (dominant) has symbol \( B \), and the allele for white fur (recessive) has symbol \( b \).
