Which allele combination represents a female who has a heterozygous sex-linked trait? xry xry xrxr xrxr

XRXr

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.

i think the answer is b.

i think its y= -4x-14
