Hello students.

Now in this question they have given the mean leg length of a locust as 18 .6 mm.
00:07
They have given the selection gradient to be 0 .13 per mm.
00:12
The phenotypic variance to be 1 .4 m m square and the heritability to be 0 .37.
00:20
They are asking the expected response and the average expected length in case of the next generation.
00:28
So first, to find the expected response, there's this formula known as r is equal to head square s, where r is the expected response, h square is the heritability and s is the selection differential.

Now, how do you find this selection differential? to find selection differential, all we need to do is there's a formula known as beta is equal to s by p, where s is the selection differential, beta is the selection gradient, and p is the phenotypic variance.

Using this can we find out? yes, right? so in this case, all we need to do is s is equal to 1 .4 into 0 .13, right? so what is the answer here? it is nothing but 0 .182...
