Question

fill in the punnett squares for two genes
in boxes a and b, the genotypes are shown for you. you need to determine the phenotypes. in boxes c
and d, you must figure out the genotypes yourself first. then, determine the phenotypes.
black fur, black eyes
black fur, red eyes
white fur, red eyes
white fur, black eyes

Explanation:

Step1: Determine Genotype of Box C

The row is 'be' and the column is 'bE'. So the genotype is \( bbEe \).

Step2: Determine Phenotype of Box C

Assume \( B \) (black fur) is dominant over \( b \) (white fur), \( E \) (black eyes) is dominant over \( e \) (red eyes). For \( bbEe \), since \( bb \) is recessive (white fur), and \( Ee \) (black eyes as \( E \) is dominant). So phenotype is white fur, black eyes.

Step3: Determine Genotype of Box D

The row is 'be' and the column is 'be'. So the genotype is \( bbee \).

Step4: Determine Phenotype of Box D

For \( bbee \), \( bb \) (white fur) and \( ee \) (red eyes as \( e \) is recessive). So phenotype is white fur, red eyes.

Answer:

Box C: white fur, black eyes; Box D: white fur, red eyes.
