In a field study in a woodland ecosystem in the Serengeti region on the border of Tanzaniaand Kenya, researchers counted the number of breeding adult giraffes. They recorded 1023breeding adult males and 3948 breeding adult females.a. What is the total number of breeding adults in this population?b. What is the effective population size of this population of giraffes? Roundyour answer to a whole number.c. Explain why the effective population size is different from the number ofbreeding adults in this population.d. What proportion of the original heterozygosity would you expect to remain inthis population of giraffes after 50 generations?Please show all work. proportion of original heterozygosity remaining = Ht/H0 = (H1)t = [1-(1/2Ne)]teffective population size = Ne = [4(Nf*Nm)]/(Nf + Nm)effective population size = Ne = t/(1/N1 + 1/N2 + ... + 1/Nt)

Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
