Answer:

XRXr

Step-by-step explanation:

The X and Y chromosomes determine the sex of an individual. A female has a pair of X chromosomes, while the male has an X and Y Chromosome. Based on this, we can rule out the first two options, because those are males.

When we say heterozygous, this means that there is a dominant and recessive trait. In genotypes, dominant traits are represented by a capital letter, while the recessive traits are represented by a lower case letter So in this case, we are looking for Rr.

This means that our answer is XRXr.
