1 answer:
Answer: to illustrate how the alleles of parents might be passed on to their offspring
Explanation: This is a punnet square. Let's say your mum has brown eyes and your father has brown eyes too. Why? Their alleles (different forms of the same gene) contain the genetic information Bb and Bb. B stands from brown dominant meaning that would be your father's and mother's eye colour. However, the lowercase b represents blue eyes. They have an allele for getting blue eyes but they don't express it because it is always recessive. When the egg in a woman's womb is fertilised, it connects with the sperm cell and makes genetic information and DNA. The punnet square shows the different combinations of alleles the new baby would have. BB = brown Bb= still brown bb= blue

Answer:
a) The allele frequencies are -
b) Genotype frequencies for this population-
Explanation:
Given ,
Red color of flower is dominant to white color flower
Let "R" represents allele for red color and "r" represents allele for white color
out of flower,
are red flowers.
So the frequency of red flowers with genotype "RR" is equal to
As per hardy Weinberg's I equilibrium equation -
a) The allele frequencies are -
Frequency of genotype "rr" i.e homozygous recessive white flower is
Substituting the values of and
, in below equation, we get -
b) Genotype frequencies for this population-
