Question

question 6 why is it impossible to predict which two alleles each parent contributes for a given gene?

Explanation:

The process of allele - contribution during gamete formation is governed by the law of segregation and independent assortment. Gamete formation involves meiosis, a random process where homologous chromosomes separate and alleles segregate randomly. Also, non - homologous chromosomes assort independently. So, it is impossible to predict which two alleles each parent will contribute for a given gene.

Answer:

The process of allele segregation and independent assortment during meiosis is random.
