Question

Consider a population of tyrannosaurs (T Rex) prior to their well-know extinction. Like other reptiles, they were diploid animals. Winking, several rapid blinks of the aye, was adaptive in these creatures because males that battle their ayes were much more successful in attaching mates than were nowning. A random sample of tyrannosaurs( assume this was possible) yielded 100 individuals homozygous for allele W, 80 individuals homozygous for allele N and 20 heterozygotes. A) identify the GENOTYPES and calculate the GENOTYPIC freemcies. Show all work please, circle genotypes and their respective frequencies Consider a population of tyrannosaurs (T Rex) prior to their well-know extinction.

Explanation / Answer

In this example W is favored than N.

here it is given 100 are homozygous for W ie WW genotype number =100

similary number of NN=80 and number of NW=20

The total sample size=100+20+80=200

from this we can find the percentage of each genotype in the population

% of WW=number of WW *100/total number of individuals

ie % of WW=100*100/200=10000/200=50%

similarly % of WN=20*100/200=10%

%of NN= 80*100/200=40%

from this frequency can be find out, frequency of WW(p^2)=0.5; WN(2pq)=0.1;NN(q^2)=0.4
