The diagram attached shows the X chromosomes in a female fruit fly and the X and Y chromosomes in a male fruit fly. The two fruit flies are crossed with each other. Fill in the two chromosomes illustrating the female offspring of the fruit flies.

Answer:

See image attached.

Explanation:

We can differentiate the X chromosomes by calling the X chromosomes from the female [tex]X^f[/tex] and the X chromosome from the male [tex]X^m[/tex].

Then, we can take these pairs of chromosomes and cross them over in a Punnett square to find the possible offspring chromosome pairs.

We have for the female fruit fly:

  • [tex]X^f X^f[/tex]

We have for the male fruit fly:

  • [tex]X^m Y[/tex]

Create a Punnett square with the female's chromosomes on top and the male's chromosomes on the left.

  • [tex]\begin{array}{c|c|c|} \multicolumn{1}{c}{} & \multicolumn{1}{c}{\textbf{X}^\textbf{f}} & \multicolumn{1}{c}{\textbf{X}^\textbf{f}} \\ \cline{2-3} \textbf{X}^\textbf{m} & \text{X}^\text{f} \text{X}^\text{m} & \text{X}^\text{f} \text{X}^\text{m} \\ \cline{2-3} \textbf{Y} & \text{X}^\text{f} \text{Y} & \text{X}^\text{f} \text{Y} \\ \cline{2-3}\end{array}[/tex]

After crossing over, we can see that there are two pairs of chromosomes inside the Punnett square.

These are the possible combinations of chromosomes for the offspring of the male and female fruit fly.

Using previous knowledge, we know that females have two X chromosomes and males have one X and one Y chromosome.

Since the question wants the chromosomes for the female offspring, we will use the two X chromosomes: [tex]$X^f X^m[/tex].

The female chromosomes have two bold lines, as shown in the diagram. The male X chromosome has 2 skinny lines.

Therefore, when filling the chromosomes that illustrate the female offspring, we will fill the left chromosome ([tex]X^f[/tex]) with two bold lines, and the right chromosome ([tex]X^m[/tex]) with two skinny lines.

Attached is an image of what the chromosome pair for the female offspring should look like.
