A sexually reproducing animal has two unlinked genes, one for head shape (H) and one for tail length (T). Its genotype is HhTt. Which of the following genotypes for these two genes is possible in a gamete from this organism? 1) HT. 2) Hh. 3) HhTt. 4) T. 5) tt.

e. HTExplanation:Gametes are sex cells, which can be an egg or a sperm. They only have one allele of each gene. Head shape is a trait coded by one gene (H) and tail length is another trait coded by another gene (T) Organisms are diploid, this means they have two alleles for each gene, so in this example the animal is HhTt. But, as it was said before, gametes only have one allele of each gene, then the gametes produced will be: HT, Ht, hT and ht. From the options provided, the only one correct is HT. Hh is not correct because it has two alleles of each gene (Hh) tt is not correct for the same reason, two alleles of each gene (tt) T is not correct because the allele fo the other gene (H or h) is missingHhTt is not correct because it has two alleles of each gene...

In the gametes for the organism, the gametes would contain one allele for each trait such that fusion of gametes would restore the original number of alleles for the trait. Thus possible genotypes in the gamete from this organism include HT, Ht, hT, ht.... Show More

The correct answer is - option E) HT Explanation:Gametes are the male or female haploid cells that can unite with the another haploid cell of opposite sex that carry one copy of the allele of every gene and form the zygote.In the following question the given organism have genotype HhTt that will form gametes by the meiosis of Th, TH, tH, and ht genotype.Thus, the correct answer would be - option E....
