Question

there are two ant phenotypes in the colony you are raising. you are told when you purchased a colony of 540 ants that you could expect 3/4 of them to be gold, and 1/4 of them to be grey due to the gold trait being dominant and the grey trait being recessive. what would your expected values be in your chi - square table?
a 450 gold ants, 90 grey ants
b 432 gold ants, 108 grey ants
c 540 gold ants, grey ants will not show up at all
d 405 gold ants, 135 grey ants

Explanation:

Step1: Calculate the number of gold ants

Multiply the total number of ants by the proportion of gold ants.
$$540\times\frac{3}{4}= 405$$

Step2: Calculate the number of grey ants

Multiply the total number of ants by the proportion of grey ants.
$$540\times\frac{1}{4}=135$$

Answer:

D. 405 gold ants, 135 grey ants
