Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both ar
dlinn [17]

Explanation:

According to p²+q²+2pq=1 (Hardy-Weinberg equilibrium)

heterozygote allele will be always 2pq

<u>1. Population</u>

1. A blood group has two genotypes- IAIA and IAIO

The genotype frequency will be-

IAIA= 0.3 X 0.3 = 0.9

IAIO= (0.3 x 0.6) x 2= 0.36

Total genotype frequency = 0.9+ 0.36 =0.45 or 45%

Now 45% of 540,000= 2,43000 (A blood group)

2. B blood group has two genotypes- IAIB and IBIO

The genotype frequency will be-

IBIB= 0.1 x 0.1 = 0.1

IBIO= (0.1 x 0.6)-=0.12

Total genotype frequncy= 0.13 or 13%

popluation with B blood group=  13% of 540,000 will be 70,200

3. AB blood group is IAIB

2 x IAIB= (0.3 x 0.1) x 2= 0.6

popluation with B blood group= 6% of 540,000= 32,400

4. O blood group

2. Heterozygote

IBIO blood group

= (0.1 x 0.6) x 2  

= 0.12 or 12%

= 12%

For each of the following
labwork [276]

Answer:

A-Both

B-Unknown but you said it was fine

C- mitosis

Explanation:

Mitosis and meiosis both have interphase, in which dna is replicated (synthesis). B I don’t know, hopefully you can get that one figured out—sorry :(. Meiosis occurs twice, which is why it results in 4 cells (gametes). Hope this helps a little :)
