Answer 2

Answer:

The right answer from the given options is D). That is hybrid and dominant allele.  

Explanation:  

The linkage 'reduces' the frequency of 'hybrid' and 'dominant' allele. It is because we know Morgan ( discovered in 1910) gene located in the 'same chromosome' happens to stay together during crossing over. This tendency is named or called linkage. The linkage is broken down by the occurrence of crossing over that happens during meiosis.
