Consider a population of rock pigeons. The mean spot size on the tail of these pigeons is 0.55. You select the top 5% of pigeons based on spot size to breed. The mean spot size in these pigeons that you are breeding is 0.75. The heritability of spot size is rock pigeons is known to be 0.25. What is the response to selection (please give your answer to two decimal places)

0.05

Explanation:

Given that:

The total population mean  of the  rock pigeons = 0.55

After selection of top 5%, the mean spot size(selected population mean size) = 0.75

Then; true selection = 0.75 - 0.55

true selection (S) = 0.20

The heritability of spot size is rock pigeons is known to be 0.25.

The response to the selection can be calculated as follows:

R =

Response to selection R = heritability spot size × true selection

= 0.25 × 0.20

= 0.05

Hence, the response to selection is 0.05 to two decimal places

The response to selection is 0.05

Explanation:

We are provided with the data on a population of rock pigeons below;

The Mean of selected parents = 0.75

The Mean of offspring  = 0.55

Selection differential (S),

= Mean of selected parents - Mean of offspring

= 0.75 - 0.55

S = 0.2

The heritability, h = 0.25

The Response to selection,

R = h2S

R = heritability × Selection differential

R = 0.25 * 0.2 = 0.05

The Response to selection = 0.05

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
