Question

in a reciprocal translocation heterozygote, which of the following are true? You can choose multiple options.

Select one or more:

a. The individual with a reciprocal translocation will not produce fertile gametes.

b. In a reciprocal translocation heterozygote about 1/3 of their gametes are likely to be non-viable.

c. A reciprocal translocation does not cause phenotypic effects.

d. In a reciprocal translocation heterozygote about 1/2 of their gametes are likely to be non-viable.

e In a reciprocal translocation heterozygote some genes are missing and some genes are duplicated.

f. In a reciprocal translocation heterozygote there is the same amount of genetic information (same number of gene copies) as in a diploid individual with only normal chromosomes.

Answer 1

Correct Options are (d) ,(e) (f)

d. In a reciprocal translocation heterozygote about 1/2 of their gametes are likely to be non-viable.

f. In a reciprocal translocation heterozygote there is the same amount of genetic information (same number of gene copies) as in a diploid individual with only normal chromosomes.

Reciprocal translocation: mutual exchange of segment between non homologous.

In such translocation one break occurs at each chromosome before excahnge of segment.

Most organism with heterozygote reciprocal translocation is semi fertile.They produce half of the live offsprings didnot have this genetic mutation.This is because as the chromosome divide during meiosis there is a 50% of offsprings to mutated.
