Select the correct answer from each drop-down menu.

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 [tex]\square[/tex] chance that the offspring will be heterozygous.

[tex]\[
\begin{array}{|c|c|c|}
\hline
& W & w \\
\hline
w & Ww & ww \\
\hline
w & Ww & ww \\
\hline
\end{array}
\][/tex]

2. 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].

[tex]\[
\begin{array}{|c|c|c|}
\hline
& W & w \\
\hline
W & WW & Ww \\
\hline
W & WW & Ww \\
\hline
\end{array}
\][/tex]

Certainly! Let's work through the genetic crosses step-by-step to find the probabilities.

First Genetic Cross:

1. Parents' Genotypes:
- A heterozygous male with genotype Ww.
- A homozygous recessive female with genotype ww.

2. Possible Gametes:
- The male can produce two types of gametes: W or w.
- The female can only produce one type of gamete: w.

3. Punnett Square:

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

4. Offspring Genotypes:
- Ww (heterozygous)
- Ww (heterozygous)
- ww (homozygous recessive)
- ww (homozygous recessive)

5. Probability of Heterozygous Offspring (Ww):
- Out of the 4 possible offspring genotypes, 2 are Ww.
- Therefore, the probability is 2 out of 4, which is 0.5 or 50%.

Second Genetic Cross:

1. Parents' Genotypes:
- A heterozygous individual with genotype Ww.
- A homozygous dominant individual with genotype WW.

2. Possible Gametes:
- The heterozygous individual can produce W or w gametes.
- The homozygous dominant individual can only produce W gametes.

3. Punnett Square:

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

4. Offspring Genotypes:
- WW (homozygous dominant)
- WW (homozygous dominant)
- Ww (heterozygous)
- Ww (heterozygous)

5. Probability of Homozygous Recessive Offspring (ww):
- All possible offspring in this cross are either WW or Ww.
- Therefore, the probability of any ww offspring is 0.

So, summarizing the results:
- In the first cross, there is a 50% chance that the offspring will be heterozygous (Ww).
- In the second cross, there is a 0% chance of having a homozygous recessive (ww) offspring.
