Select the correct answer from each drop-down menu.

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

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

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

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

Answer :

Certainly! Let's solve these questions step by step.

### First Scenario

Genetics Cross:
- A heterozygous male with genotype Ww
- A homozygous recessive female with genotype ww

Punnett Square:
To predict the offspring, we can use a Punnett square. Let's fill it out:

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

- The possible genotypes for the offspring are: Ww, Ww, ww, and ww.

Probability of Heterozygous Offspring (Ww):
- There are 2 heterozygous outcomes (Ww) out of 4 total possibilities.

So, there is a [tex]\( \frac{2}{4} \)[/tex] or 0.5 probability that the offspring will be heterozygous.

### Second Scenario

Genetics Cross:
- A heterozygous individual with genotype Ww
- A homozygous dominant with genotype WW

Punnett Square:
Let's fill out the Punnett square for this cross:

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

- The possible genotypes for the offspring are: WW, WW, Ww, and Ww.

Probability of Homozygous Recessive Offspring (ww):
- There are 0 outcomes with ww because all combinations result in either WW or Ww.

Thus, the probability of having a homozygous recessive offspring is 0.

In summary, for the first scenario, the probability of having heterozygous offspring is 0.5, and for the second scenario, the probability of having homozygous recessive offspring is 0.0.
