Verified Answer :

Answer;

The female genotype is Tt or heterozygous

Explanation;

-Alleles are the alternative forms of a gene. These forms may be either homozygous , where a trait has two similar alleles for a given trait, or heterozygous where the alleles are different, such that there is one allele that is dominant over the other.

-In this case the sperm genotype is homozygous recessive, where the two alleles are similar and are both recessive. The female genotype on the other hand is heterozygous, where one allele is dominant, T, over the other one which is recessive, t.


Ans.

The genotype represents genetic makeup of an organism. At the time of sexual reproduction, female produces haploid gametes or ova, while male produces sperm.  

According to given punnet square, female is forming two types of ova with genotype T and t. Hence, the genotype of female is Tt.  

In given punnet square, T and t are showing two different alleles (alternative form) of a particular gene. An organism with two different alleles for a particular gene is called as heterozygous. Hence, according to the punnet square, the female is heterozygous.  

Thus, the options). 'Tt' and 'heterozygous' are correct.
