. 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

Let me give some information about this.

Lyases are the main groups which show peculiarity in having more than several categorised groups having more enzymes than the other four.

Hydrolase does not fit this bill instead they contain less categorised groups.

Other two groups are not even having that much groups.

Hope helps ...

Which part of the cell membrane prevents the cell from dissolving in water​
fredd [130]

Answer:

As the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
