Answer :
Sure! Let's go through the genetics scenario step-by-step.
### First Scenario
Cross: Heterozygous male (Ww) with Homozygous recessive female (ww)
1. Parental Genotypes:
- Male: Ww
- Female: ww
2. Possible Gametes:
- Male (Ww) can produce gametes carrying either W or w.
- Female (ww) can produce gametes carrying w.
3. Punnett Square:
| | W | w |
|---|---|---|
| w | Ww | ww |
| w | Ww | ww |
4. Offspring Genotypes:
- Two possible outcomes:
- Ww (Heterozygous)
- ww (Homozygous recessive)
5. Probability of Each Genotype:
- 50% of the offspring will be heterozygous (Ww).
### Second Scenario
Cross: Heterozygous male (Ww) with Homozygous dominant female (WW)
1. Parental Genotypes:
- Male: Ww
- Female: WW
2. Possible Gametes:
- Male (Ww) can produce gametes carrying either W or w.
- Female (WW) can produce gametes carrying W.
3. Punnett Square:
| | W | W |
|---|---|---|
| W | WW | WW |
| w | Ww | Ww |
4. Offspring Genotypes:
- Two possible outcomes:
- WW (Homozygous dominant)
- Ww (Heterozygous)
5. Probability of Each Genotype:
- 0% chance of having homozygous recessive offspring (ww).
By following these genetic crosses, we find that:
- In the first scenario, there's a 50% chance that the offspring will be heterozygous (Ww).
- In the second scenario, there's a 0% chance that the offspring will be homozygous recessive (ww).
