. The mean grain yield of an open pollinated rye breeding population is determined to be 72 bushels/acre. Your goal is to improv

e grain yield in this population. The mean grain yield of selected individuals from this population is 93 bushels/acre. Selected individuals are intermated to form a new population. The new population mean is determined to be 84 bushels/acre. With this information, calculate the selection intensity, response to selection and heritability of grain yield. (3) Report your answers for A and B as whole numbers and your answer for C to 2 decimal places.

Answer:

a) the selection intensity is 21bushels/acre

b) the response to selection is 12bushels/acre

c) The heritability is 0.57 (two decimal places)

Explanation:

Given:

mean grain yield population=72bushels/acre

mean grain yield selected individuals=93bushels/acre

mean grain yield new population=84busgels/acre

a) The selection intensity is given by:

SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre

b) The response to selection is:

RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre

c) The heritability of grain yield is:

H=RS/SI=12/21=0.57

Hope you get it right good luck!

hope this helps

Explanation:

About 95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.
