1. 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 [tex]\square[/tex] of the offspring will be heterozygous.

Answer :

Certainly! Let's solve the problem step by step:

### Scenario 1:
A heterozygous male with genotype Ww is mated with a homozygous recessive female of genotype ww.

1. Parent Genotypes:
- Male: Ww
- Female: ww

2. Possible Offspring Combinations:
- From Ww (male), we can pass on either W or w.
- From ww (female), we can only pass on w.

3. Offspring Genotypes:
- Ww (W from male and w from female)
- ww (w from male and w from female)

4. Punnett Square:

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

5. Chances of Offspring Being Heterozygous (Ww):
- Ww appears in 2 out of 4 possible outcomes (Ww, ww, Ww, ww).

Therefore, there is a 0.5 (or 50%) chance that the offspring will be heterozygous (Ww).

### Scenario 2:
A heterozygous Ww is crossed with a homozygous dominant WW.

1. Parent Genotypes:
- Heterozygous: Ww
- Homozygous Dominant: WW

2. Possible Offspring Combinations:
- From Ww, pass on W or w.
- From WW, only possible to pass on W.

3. Offspring Genotypes:
- WW (W from Ww and W from WW)
- Ww (w from Ww and W from WW)

4. Punnett Square:

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

5. Probability of Having a Homozygous Recessive Offspring (ww):
- There are no ww combinations possible with these parents.

Therefore, the probability of having a homozygous recessive offspring (ww) is 0.0 (or 0%).

In summary, in the first scenario, 50% of the offspring are expected to be heterozygous, and in the second scenario, there is a 0% probability of having a homozygous recessive offspring.
