Inheritance

Question 1

Gene

Answer 1

Length of DNA that codes for a polypeptide

Question 2

Allele

Answer 2

Different form of a gene

Question 3

Genotype

Answer 3

Genetic constitution of an organism

Question 4

Phenotype

Answer 4

Expression of a genotype and its interaction with the environment.

Question 5

To work out the frequency of an allele, what equation should I use?

Answer 5

P+q = 1
p = f(A)
q= f(a)

Question 6

Genotype frequency

Answer 6

(p)2 + 2(pq) +(q)2 = 1

(p)2 = frequency of homozygous genotype (A)
2(pq) = new freq. of heterozygous genotype (Aa)
q = freq. of other homozygous genotype (aa)
