A population has a gene with 2 alleles, G and g. The frequency of the G allele is 0.8. The frequency of the g allele is 0.2. Thi
Pavel [41]

Answer: The frequency of GG is 0.64

Explanation: using Hardy-weinberg equation

g^2 + 2Gg + G^2 =1 ................(1)

And the sum of the alleles at the locus must be 1.

Therefore:

G + g = 1 ..............................(2)

Since

G=0.8

g= 0.2

G^2 =GG (Homozygous G gene)

g^2 = gg (Homozygous g gene)

Using equation 1

GG+ (2×0.8×0.2) + gg =1

Therefore

GG + 0.32 + gg = 1

GG + gg = 0.68...............(3)

Solving equation 2

G + g = 1

g = 1 - G

Square both side

g^2 = (1 - G)^2 ...............4

Where g^2 = gg

Therefore gg = (1 - G)^2.............(5)

Substitute equation 5 into equation 3

GG + (1 - G)^2 = 0.68

Therefore

GG = 0.68 - (1 - G)^2

GG = 0.68 - (1 - 0.8)^2

GG = 0.68 - 0.04

GG = 0.64

Which of the following statements about homologous chromosomes is correct?
frez [133]
The answer is <span>a. Each gene is at the same locus on both chromosomes.

Since e</span><span>ach gene is at the same locus on both chromosomes, they are able to pair correctly before they separate in meiosis. They never produce identical phenotypes. Also, the genes and alleles on the homologous chromosomes are not identical. </span>

Earth’s landscape can change over time. What can happen to a watershed as a result?
melamori03 [73]
Through weathering and the erosion of rocks and soil, Earth’s landscape can change drastically overtime. As a result, watersheds may disappear if the land making the watershed is worn away, and the water collected is <span>able to flow back into the river, as the area is level with the rest of the land.</span>
