If two intermediate-colored chickens together produced 100 chicks, how many would you expect to be black?
sergiy2304 [10]

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.

What factor defines all groups in the Köppen system, with the exception of dry climates? evaporation precipitation air pressure
Liula [17]

Answer:

temperature

Explanation:

I choose temperature because it tells how hot,cold,dry and warm somethings are meanwhile evaporation is when water changes from liquid to gas,so that means water gets hot.

Precipitation is when water released from the cloud to form rain,freezing rain,sleet,snow,or hail.Which means thing get cold.

Air pressure also affect evaporation, which means that water will not be able to come up of the surface of a body of water.So that means the the pressure will be pushing down on the surface of the water.
