so for the 2nd question: an herbivore that eats only narrow leaves (organism with bb genotypes) will decrease f(b) and increase f(B)

And for the 1st question:

you have to calculate the allele frequencies for each generation and u can do that by writing 2 equations. After u find the values of f(b) and f(B) for each generation by comparing the values you can tell wether or not this population is in equilibrium. If the values have stayed fairly the same that means it’s in equilibrium and it is not evolving. I think this population is not in equilibrium and thus is evolving by looking at the numbers in the table.

If you still have questions or problems with the calculations leave a comment and I’ll help. :))

A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (

Paul [167]

Answer:

frequency of the blue (B) allele $= 0.4142$

frequency of the red (R) allele $= 0.5858$

The number of blue plants expected is $509.652$

The number of red plants expected is $1019.304$

The anticipated number of violet plants is $1441.341$

Calculated chi square value

$= 84.5320 + 42.5688 + 119.8692\\= 246.97$

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

$\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142$

Frequency of other allele

$1- 0.4142\\= 0.5858$

Chi Square test

See the attached file

The number of blue plants expected is $509.652$

The number of red plants expected is $1019.304$

The anticipated number of violet plants is $1441.341$

Calculated chi square value

$= 84.5320 + 42.5688 + 119.8692\\= 246.97$
