Answer:
The types of gamete in a heterozygous individual for the FXN gene will be two. A dominant gamete, which contains the "A" allele and a recessive gamete, which contains the "a" allele.
Explanation:
When an individual is heterozygous for a given gene, it means that that individual has different gametes (related to that gene), with that, that individual will generate two types of gamete; a dominant gamete with the "A" allele and a recessive gamete with the "a" allele.
If the individual is homozygous dominant, he will only generate one type of gamete, which is the gamete with the "A" allele. however, if the individual is homozygous recessive, he will only generate one type of gamete, which is the gamete with the "a" allele.
