Answer:
a) The equation describes the relationship between p and q is p + q = 1 for allelic frequencies
b) The frequencies of alleles A1 in decimals is 0.7 and in percents is 70%.
The frequencies of alleles A2 in decimals is 0.3 and in percents is 30%.
Explanation:
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the same way, the sum of genotypic frequencies equals 1, this is
p2 + 2pq + q2 = 1
Being
- p the dominant allelic frequency,
- q the recessive allelic frequency,
- p²the homozygous dominant genotypic frequency
- q² the homozygous recessive genotypic frequency
- 2pq the heterozygous genotypic frequency
In the exposed example,
- A1 codes for purple leaves, has a frequency of 0.7 and is dominant.
- A2 codes for white leaves, has a frequency of 0.3 and is recessive.
According to this equation: p + q = 1.
0.7 + 0.3 = 1
A1A1= p²= 0.7² = 0.49
A2A2= q² = 0.3² = 0.09
A1A2 = 2pq = 2 x 0.7 x 0.3 = 0.42
According to this equation: p² + 2pq + q² = 1
0.49 + 0.42 + 0.09 = 1
- The frequencies of alleles A1 in decimals is 0.7 and in percents is 70%.
- The frequencies of alleles A2 in decimals is 0.3 and in percents is 30%.
Synapse is the correct answer :)
The woolly mammoth was an animal used to artic, or colder conditions. When the Ice Age ended, the woolly mammoth couldn't handle the warmer temperatures. It also was being hunted for food. People could have hunted it out of extinction.
