Answer 0

frequency of desired genes is increased

Question 1

__________ is a process of differential reproduction

Answer 1

selection

Question 2

define “response to selection/genetic change/genetic gain”

Answer 2

change in performance of progeny generation due to artifical selection

Question 3

selection divides parental population into 2 parts i.e.

Answer 3

selected

culled

Question 4

define selection differential

Answer 4

superiority of selected parents over population mean

Question 5

phrnotypic superiority of selected parents is equal to

Answer 5

S=genetic superiority + enviromental superiority

Question 6

which part of genetic variability is inherited

Answer 6

additive genetic variability

Question 7

what does heritability express

Answer 7

the extend to which the total phenotypic superiority of a trait shown by selected parents is transmitted to their progeny

Question 8

formula of heritability

Answer 8

additive genetic variability/phenotypic variability

Question 9

define “predicted response to selection”

Answer 9

expected inherited part of selection differential

Question 10

formula of “predicted response to selection”

Answer 10

R=heritability * selection differential
