Subject:BiologyPrice:2.84 Bought7
Two loci are involved with blood type determination, the ABO locus and the Rhesus locus. The allele frequencies are indicated below. Blood alleles IA and IB are co-dominant and both are dominant to IO. Rh+ is fully dominant to Rh-.
A = 0.15 Rh+ = 0.65
B = 0.12 Rh- = 0.35
O = 0.73
What is the probability you will find a person who is type A, Rh positive in this population?
In this case,
P (Type A, Rh+ person)
P (Type A) *P(Rh+)
Step-by-step explanation
Given the following variables, what is the probability you will find a person who is type A, Rh positive in this population?
A = 0.15 Rh+ = 0.65
B = 0.12 Rh- = 0.35
O = 0.73
Answer:
In this case,
P (Type A, Rh+ person)
P (Type A) *P(Rh+)
= 0.15*0.65
= 0.0975
Hence, the probability you will find a person who is type A, Rh positive in this population is 0.0975.
