The Hardy-Weinberg theorem states that the gene frequency of populations does no

Question

The Hardy-Weinberg theorem states that the gene frequency of populations does not change over time. TRUE OR FALSE?

Evolution by natural selection is a random process. TRUE OR FALSE?

In a population of 50 individuals, 20 are homozygous dominant, 25 are heterozygous, and 5 are homozygous recessive. If 20% of the DOMINANT PHENOTYPE are eaten by birds, what will be the NEW RECESSIVE ALLELE FREQUENCY in the remaining population?

(Hint: How many individuals express the dominant phenotype in the current population? In the new population?)

A.30% (0.30)

10% (0.10)

36.5% (0.365)

12.1% (0.121)

Explanation / Answer

The Hardy-Weinberg theorem states that the gene frequency of populations does not change over time. TRUE

Evolution by natural selection is a random process. TRUE


In a population of 50 individuals, 20 are homozygous dominant, 25 are heterozygous, and 5 are homozygous recessive. If 20% of the DOMINANT PHENOTYPE are eaten by birds, what will be the NEW RECESSIVE ALLELE FREQUENCY in the remaining population?

20 are homozygous dominant, 25 are heterozygous=45 x20%=9

45-9=36

36+5=41

q^2= 5/41

=0.34 answer
(Hint: How many individuals express the dominant phenotype in the current population? In the new population?)
Question 9 options:

p=1-0.34=0.66

=0.66x0.66x41=17.85

2pq= 2 x0.66x0.34x41=18.4

A.30% (0.30)
B. 10% (0.10)
C. 36.5% (0.365)
D. 12.1% (0.121)
