1. Imagine a population of 100 snails in which the shell colour is controlled by two alleles: B (black) and b (yellow). () What is the total number of loci for shell colour gene in this population? In the snail population described above, 20 out of the snails are yellow (bb) and 80 are black (BB or Bb). Of the 80 black snails=, 30 are homozygous and 50 are heterozygous. How many loci for this gene are occupied by the B (i) allele? (ii) What is the frequency of the B allele? (iv) Assuming that sexual reproduction takes place with random mating, no gene flow and no selection, what will be the frequency of yellow snails in next generation of the population described above? (v) What will be the frequency of the b allele in the next generation of the snail population described below

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
