Answer: 25 of the chicks will be black
Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.
Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.

Answer:
The correct answer is - 11.25
Explanation:
Given:
Average weight gain between weeks 2 and 4 = 10 grams
The narrow-sense heritability of the weight gain between 2 and 4 weeks
= 25%
Then
Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-
by the formula:
Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )
= 10 + 0.25 (15-10)
= 10 + 0.25 (5)
= 10 + 1.25
= 11.25
Thus, the correct answer is - 11.25

Explanation:
In all living system we can always find basic elements carbon, oxygen, nitrogen and hydrogen, carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.0% oxygen and hydrogen are present in almost all organic compound which creates living organisms.
