Question

Many people who are heterozygous for a reciprocal translocation suffer from semisterility. Which of the following does not contribute to their partial loss of fertility?

a. Adjacent-2 segregation
b. Adjacent-1 segregation
c. Alternate segregation
d. The amount of genetic material remains constant

Answer 1

d. The amount of genetic material remains constant

Step-by-step explanation:

Adjacent-1 segregation is the segregation of normal chromosomes with segregated chromosomes. Alternate segregation is the segregation of two normal chromosomes. Adjacent-2 segregation is the segregation of homologous chromosomes.

Semi sterility is a condition as a result of the equality between adjacent and alternate segregations causing about half of the gametes to die. Semi sterility is usually found in heterozygous with translocation.
