Question
I have an assignment question asking -

Researchers at Jurassic Park found genes that code for fang length, arm length and toe siz of T.rex. Each of these genes only has 2 alleles (F&f, A&a, T&t) and each gene is located on a diff. pair of homologous chromosomes. If a male and female both of whom are heterozygous for all 3 traits, were to mate how many diff gametes could each produce as fas as these 3 traits?

Could u pls show the genetic make up all of the diff gametes for the 3 genes that these dinosaurs that are heterozygous for all 3 traits could produce.

Pls help me today.. it's due on Friday..

THANK YOU SO MUCH!!
