An individual possesses two alleles at a locus and these two alleles separate when gametes are formed, one allele going into each gamete. This genetic concept is known as

a. the chromosome theory of heredity.
b. principle of segregation.
c. concept of dominance.
d. principle of independent assortment.
e. reciprocal cross.

Respuesta :

Answer: Option B) principle of segregation.

Explanation:

The principle of segregation is also known as Mendel's 1st law of heredity. It explains how a diploid individual with two different alleles (heterozygous) occupying the same locus on the homologous chromosomes e.g "Rr", would seperate to yield 'R' and 'r'.

Then, the alternative alleles 'R' and 'r' seperated during meiosis would each go randomly to a different gamete to be crossed with other gametes to form a zygote with diploid number as offspring having a different genetic constituent to that of the parents

Thus, the principle of segregation is the answer.
