Question

Question 3 1 pts Which of the following is TRUE about coalescent theory? The coalescent point represents the origin point of a particular allele Loci that are under directional selection exhibit shorter coalescent times than neutral loci in the same population The coalescence time can be used to calculate the mutation rate for a locus O Coalescence times will be shorter in larger populations Question 4 1 pts In a very large population of plants, 50% of AA individuals survive to adulthood, and those that do produce on average 20 seeds. 60% of Aa individuals survive to adulthood, and those that do produce on average 30 seeds. 65% of aa individuals survive to adulthood, and those that do produce on average 35 seeds. What will happen to the allele frequencies in this population? The A and a alleles will both persist in the population at about their current frequencies The A allele will go to fixation because it is dominant The a allele will go to fixation because individuals with the a allele have higher fitness O The a allele will be eliminated because it is recessive

Answer 1

3) Coalescent theory suggest that origin of allele from origin point so option 1 is correct

The Coalescent point represent the origin point of allele

4) Frequency of A allele= (50+1/2x60)/175= (50+30)/175= 80/175= 0.457

Frequency of a allele= (65+1/2x60)/175= (65+30)/175= 95/175= 0.543

So after several generations a allele become more and more selected while A allele become less and less selected and one time A allele become eliminated.

So 3rd option correct as the a allele will go to fixation because indivisuals with the a allele have higher fitness.

Hope it's clear..thanks
