The correct answer is option D) six dominant and two recessive.

Explanation:

The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).

Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.

Thus, the correct answer is option D) six dominant and two recessive.
