maksim [4K]
<h2>Frequency of allele </h2>

Explanation:

Hardy Weinberg Equilibrium is used to calculate the allelic as well as genotypic frequency

Allelic frequency of dominant and recessive allele is represented by p and q respectively whereas genotypic frequency of dominant genotype is represented by p2 and q2 respectively

Given:

H allele (p) = hairy heffalump (dominant)

h allele (q) = hairless heffalump (recessive)

36% of heffalump population is hairless represents the % of recessive genotype, hh (q2) =36%

Calculation of frequency of the h allele (q) :

Frequency of genotype hh (q2) will be: 36/100=0.36 or 0.6*0.6

Frequency of h allele (q) will be 0.6

A simplified model of the human blood-type system has four blood types: a, b,ab and o. thereare two antigens, anti-a and anti-b.
Kay [80]
First calculate the probability of type AB, which is the remainder after subtracting types A, B and O.

P(AB) = 1-(0.34+0.12+0.5) = 1-0.96 = 0.04

Anti-b will react with types B and AB, so 
P(reaction) = P(B)+P(AB) = 0.12 +  0.04 = 0.16

Answer: For this person, the probability of reaction with anti-b is 0.16
