To determine the possible genotypes for the female based on the Punnett square provided, we need to analyze the crosses represented in the square.
The Punnett square is as follows:
[tex]\[
\begin{array}{|c|c|c|}
\hline & T & t \\
\hline
t & Tt & tt \\
\hline
t & Tt & tt \\
\hline
\end{array}
\][/tex]
### Step-by-Step Solution:
1. Interpreting the Punnett Square:
- The rows and columns each represent the alleles contributed by each parent.
- The alleles [tex]\(T\)[/tex] and [tex]\(t\)[/tex] suggest one parent (male) contributes [tex]\(T\)[/tex] and [tex]\(t\)[/tex], while the other parent (female) contributes [tex]\(t\)[/tex] only.
2. Possible Genotypes for Progeny:
- By filling in the Punnett square, we see the combinations of alleles:
- [tex]\( T \times t = Tt \)[/tex] (Heterozygous)
- [tex]\( t \times t = tt \)[/tex] (Homozygous recessive)
- This pattern repeats for the second row.
3. Determining the Female Genotype:
- Since the female provides the alleles in the rows labeled [tex]\(t\)[/tex], she must have genotype [tex]\(tt\)[/tex].
4. Identifying the Specific Terms:
- [tex]\(tt\)[/tex]: This indicates the female is homozygous recessive.
- [tex]\(Tt\)[/tex]: Not possible for the female because she only provides [tex]\(t\)[/tex].
- homozygous: Correct, because [tex]\(tt\)[/tex] is a homozygous genotype.
- heterozygous: Incorrect, because the female does not have a combination of [tex]\(T\)[/tex] and [tex]\(t\)[/tex].
### Conclusion:
Based on the Punnett square analysis, the female genotype can be described using:
- tt
- homozygous
Therefore, the female genotype options include tt (homozygous recessive) and she is considered homozygous. Additionally, male could be either heterozygous Tt or homozygous recessive tt.
Thus, the valid options to describe the female genotype are:
- tt
- homozygous
