Henry the horse has 64 chromosomes in a liver that is begining mitosis . How many chromosomes will the resulting daughter cell e
Ber [7]

Each of the resulting daughter cells will have 64 chromosomes.  

Mitosis is one of the components of the cell cycle when the duplicated chromosomes are distinguished into two nuclei. In mitosis, the two resulting daughter cells will always comprise of the similar quantity of chromosomes as the parent cell from which they are obtained.  

The main function of mitosis is to keep the number of chromosomes constant in each cell division, thus, permitting one to grow and self-sustain the bodies.

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
