Question

determine the phenotypes of the offspring shown in the punnett square. bb: black fur bb: black fur bb: white fur complete there are four different combinations of offspring genotypes in every punnett square. fill in the blanks below to complete the ratio for the punnett square shown to the right. black fur:white fur = :

Explanation:

Step1: Count black - fur genotypes

Count the number of genotypes that result in black fur. Genotypes BB and Bb result in black fur. In the Punnett - square, there is 1 BB and 2 Bb, so there are 1 + 2=3 black - fur genotypes.

Step2: Count white - fur genotypes

Count the number of genotypes that result in white fur. The genotype bb results in white fur. In the Punnett - square, there is 1 bb.

Answer:

3:1
