Question

If there are 4000 children born to this generation, how many would be expected to have ab blood under the conditions of hardy-weinberg equilibrium

Answer 1

`1920`

Step-by-step explanation:

Complete Question -

In a hypothetical population of 1,000 people, tests of blood-type genes show that 160 have the genotype AA, 480 have the genotype AB, and 360 have the genotype BB.

If there are 4,000 children born to this generation, how many would be expected to have AB blood under the conditions of Hardy-Weinberg equilibrium?

Solution -

Frequency of having people with blood group AA

`(160)/(1000) \\= 0.16`

Frequency of having people with blood group AB

`(480)/(1000) \\= 0.48`

Frequency of having people with blood group BB

`(360)/(1000) \\= 0.36`

Sum of all the genotype frequencies must be equal to 1 in order to be in hardy-weinberg equilibrium

Thus,

`0.16 + 0.36 + 0.48 = 1\\`

Hence, the given population is in hardy-weinberg equilibrium

Number of children to have AB blood
`0.48` times of the total population

Thus out of
`4000` people , number of people with AB blood group is equal to

`0.48 * 4000\\1920`
