Question

AlleleA1 program Natural selection ASAP please please

Please help if you know about this program, because ihave truble with explaining rezults. thank you!!!

1. Set the fitness value of A1A1 genotype to 0.9 .Describe and explain results?

2. There's horizontal line ,explain why a horizontal line is expected?

3. Is it possible that two genotype (see image) have the same fitness values? How such a situation could arise in an actual population?

Al: 0.02062 A2: 0.97938 AIA1: 0.00043 A1A2: 0.04039 A2A2: 0.95918 0.6 Frequency of allele Al 0.4 0.2- ip 0 100 200 300 400 500 Generation Sartng frequency of alele Al: 0.5Faction migrants each gener Fraction migrants each generation: 0 Frequency of A1 in source pop'n 0.5 Fitness of genotype AIA1 0.9 Fitness of genotype AlA2: 1.0 Fitness of genotype A2A2: 1.0 Mutation rate from Al to A2: 0 Mutation rate from A2 to Al 0 Population size: Infinite 0 Inbreeding coefficient (F: O Graph lines ht-Single ',Multiple OAura ー/RunL clear n Reset -

Thank you!!

Answer 1

1- This is the case of recessive allele advantage . As you see that genotype containing A2 allele has fitness of 1 where as genotype which does not contain A2 allele i. e. A1A1 has less fitness than A2 containing genotypes.

In our results, there are more number of A2A2 and A1A2 genotype individual. A2 allele is not fixed because A1A2 has also fitness of 1.

2- Blue line indicates Hardyweinberg equilibrium condition.

This is showing the ideal condition of Hardyweinberg equilibrium i.e. random mating, no migration, no selection etc.

3- Yes it is possible that two genotype has same fitness.

In this we can say that allele A2 codes for a trait which is favourable by the environment and has fitness of 1.
