In guinea pigs black hair color is dominant B and white recessive b What are the offspring?

You're asking about a classic genetics scenario! To figure out the offspring, we need to know the genotypes of the parents. Here's how it works:

Understanding the Terms:

* Dominant: The dominant allele (in this case, 'B' for black hair) masks the recessive allele.

* Recessive: The recessive allele (in this case, 'b' for white hair) only shows up if there are two copies of it.

Possible Parent Genotypes:

* Parent 1 (Black):

* BB: Homozygous dominant (will always produce black offspring)

* Bb: Heterozygous (has both black and white alleles, will produce mostly black offspring)

* Parent 2 (White):

* bb: Homozygous recessive (will always produce white offspring)

Possible Offspring Scenarios:

Let's look at the possible combinations for each parent pair:

1. Parent 1 (BB) x Parent 2 (bb):

* All offspring will be Bb (black). This is because they inherit a 'B' allele from the black parent and a 'b' allele from the white parent.

2. Parent 1 (Bb) x Parent 2 (bb):

* 50% of offspring will be Bb (black).

* 50% of offspring will be bb (white).

Punnett Square:

A Punnett square is a helpful tool for visualizing these crosses:

| | b | b |

|----------|-----|-----|

| B | Bb | Bb |

| b | bb | bb |

This shows the possible combinations of alleles for each offspring.

To answer your question, you need to tell me the genotypes of the parent guinea pigs!
