in boxes a and b, the genotypes are shown for you. you need to determine the phenotypes. in boxes c and d…

Explanation:

Step1: Understand dominant - recessive relationships

Assume B is dominant for a certain trait (e.g., black fur) and b is recessive (e.g., white fur), and E is dominant for another trait (e.g., red eyes) and e is recessive (e.g., black eyes).

Step2: Determine phenotype of BOX A (BBEe)

Since B is dominant and there are two B alleles, the fur - related phenotype will show the dominant trait. For the eye - related trait, with one E (dominant) and one e (recessive), the eye phenotype will show the dominant trait. So the phenotype is black fur and red eyes.

Step3: Determine phenotype of BOX B (BBee)

With two B alleles, the fur phenotype is the dominant trait. For the eye trait, with two e (recessive) alleles, the eye phenotype is the recessive trait. So the phenotype is black fur and black eyes.

Step4: Determine genotype of BOX C

The possible genotype of BOX C is BbEe (from the cross of the given parents).

Step5: Determine phenotype of BOX C (BbEe)

Since B is dominant and there is at least one B, the fur phenotype is the dominant trait. Since E is dominant and there is at least one E, the eye phenotype is the dominant trait. So the phenotype is black fur and red eyes.

Step6: Determine genotype of BOX D

The possible genotype of BOX D is Bbee (from the cross of the given parents).

Step7: Determine phenotype of BOX D (Bbee)

With at least one B, the fur phenotype is the dominant trait. With two e alleles, the eye phenotype is the recessive trait. So the phenotype is black fur and black eyes.

Answer:

BOX A: Black fur, red eyes BOX B: Black fur, black eyes BOX C: Black fur, red eyes BOX D: Black fur, black eyes
