If a heterozygous male with the genotype [tex]Ww[/tex] is mated with a homozygous recessive female of genotype [tex]ww[/tex], there is a chance that of the offspring will be heterozygous. [tex]\square[/tex]

If the heterozygous [tex]Ww[/tex] is crossed with a homozygous dominant [tex]WW[/tex], then the probability of having a homozygous recessive offspring is [tex]\square[/tex]

Answer :

Sure! Let's go through each scenario step-by-step to determine the probabilities of having certain types of offspring.

### First Scenario: Heterozygous Male (Ww) × Homozygous Recessive Female (ww)

1. Parental Genotypes:
- Male: Ww (heterozygous)
- Female: ww (homozygous recessive)

2. Possible Gametes:
- Male can produce: W or w
- Female can produce: w

3. Punnett Square:

```
| W | w |
----------------
w | Ww | ww |
----------------
w | Ww | ww |
```

4. Resulting Offspring Genotypes:
- Ww appears twice
- ww appears twice

5. Probability Calculation:
- Heterozygous (Ww) offspring: 2 out of 4, or 50%

So, there is a 50% chance that the offspring will be heterozygous (Ww).

### Second Scenario: Heterozygous (Ww) × Homozygous Dominant (WW)

1. Parental Genotypes:
- One parent is Ww (heterozygous)
- The other is WW (homozygous dominant)

2. Possible Gametes:
- Ww parent can produce: W or w
- WW parent can produce: W

3. Punnett Square:

```
| W | W |
----------------
W | WW | WW |
----------------
w | Ww | Ww |
```

4. Resulting Offspring Genotypes:
- WW appears twice
- Ww appears twice

5. Probability Calculation:
- Homozygous recessive (ww) offspring: 0 out of 4, or 0%

So, there is a 0% chance of having a homozygous recessive (ww) offspring in this scenario.

In summary:
- For the first scenario, the chance that the offspring will be heterozygous (Ww) is 50%.
- For the second scenario, the probability of having a homozygous recessive (ww) offspring is 0%.
