Answer:
e. both b. and c. are correct
Step-by-step explanation:
According to Mendel's law of segregation, each genetic trait is regulated by a pair of factors, alleles. These genetic factors are present as distinct particles.
The two alleles of a gene occupy the corresponding position on the homologous chromosomes. The two alleles of a gene are separated from each other during gamete formation due to the separation of homologous chromosomes during anaphase-I of meiosis-I.
This leads to the formation of gametes carrying one allele for each gene. This is the reason that the law of segregation is also called the law of purity of gametes.
