What are the chances of the offspring being homozygous brown haired?
gametes B and b; B and b each parent prodices 2gametes
Use a Punnet square.

I hope this helps. Thanks for asking.
To determine the chances of the offspring being homozygous brown-haired, we need to consider the genotype and possible combinations of the parents' gametes. Let's break it down step by step:
1. We have two parents, with each parent producing two gametes. Let's label them as follows:
Parent 1: Gamete B and Gamete b
Parent 2: Gamete B and Gamete b
2. To determine the possible combinations of the parents' gametes, we can use a Punnett square. The square will have two rows and two columns, representing each parent's gametes.
| Parent 1 | Parent 2 |
----------------------------
Row1 | BB | Bb |
----------------------------
Row2 | bB | bb |
----------------------------
3. Now, let's examine the combinations in the Punnett square that represent the offspring being homozygous brown-haired (BB):
- Out of the four possible combinations, only one combination, BB, represents homozygous brown-haired offspring.
4. Therefore, the chance of the offspring being homozygous brown-haired is 1 out of 4, or 1/4, which can be stated as 25%.
So, the chances of the offspring being homozygous brown-haired, based on the given gametes, are 25%.
