Question

In a very large diploid population, a new mutation arises that improves the probability that the individual it arose in will survive to reproductive maturity by 2.3%. What is the probability that this mutation will become fixed in the population?

Answer 1

Answer: In a diploid population consider a trait on a certain location has two allele A and B, therfore the number of genotypes outcome possible from the above two alleles is AA (homozygous), BB (Homozygous), AB (heterozygous).

Similarly if we have A and b allele then genotypes will be AA (homozygous), Ab (heterozygous), bb(homozygous)

For expressing any trait in a population such as sudden mutation it depends either the changes is at dominant allele of autosomes or at recessive allele of trait, or the changes are happening at the sex chromosomes that will be inherited by further offspring and will be followed through generation. Such as example diabetes is a X -linked disease that's why it is considered as a hereditary disorder. Similarly if the mutation is happening at the dominant allele of the gene that is affecting the reproducibility outcome directly than most probably it will affect 75% of the allele frequency and chances will be more here in future generation to repeatedly inherit such change compare to if mutation is occuring at the recessive allele than most probably 25% of the population will be affected by such changes.
