Answer: The correct answer for the blank is-

Homozygous dominant.

Explanation:

According to Mendelian inheritance, every trait (characteristic) of organsim is governed by pair of genes (that exist in two different forms, recessive and dominant allele).

Dominant allele (expressed in capital letter) masks the expression of recessive allele that is expressed in small letter.

There are two possible genotypes for dominant trait, such as 'tall pea plant' can be expressed by TT (homozygous dominant, since both alleles are same) and Tt (heterozygous dominant, since both are different alleles).

Thus, TT depicts homozygous dominant genotype.

The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
