Homo sapiens means wise human being, it one of several species grouped into the genus Homo, but it is the only one that is not extinct. It is the specie where all human beings belong.

Answer:
d. He observed that both dominant traits always hid the recessive traits in these double crosses.
Explanation:
<em>The observation that the dominant traits hid the physical expression of recessive traits in dihybrid cross helped Mendel to formulate the law of independent assortment of genes.</em>
The law of independent assortment of genes states that traits are inherited independently of one another without any form of interference.
For example, the trait for height (T, tallness is dominant over t, shortness) and seed shape (smooth, S is dominant over wrinkle, s) will be independently inherited in a cross involving the two traits.
<em>The ratio of tall individuals to short individuals and that of smooth individuals to wrinkle individuals at F2 will both be 3:1, which is the same standard ratio that will be obtained if the traits are considered independently.</em>
The correct option is d.
