Hi! :)
Make a = q, aa (homozygous recessive) = q^2,
A = p, AA (homozygous dominant) = p^2, and
2pq = heterozygous
This was derived from p + q = 1
Therefore all a in pop (q) = 20% = .20
And all A in pop (p) = 80% = .80
Since the disease is homozygous recessive (affected), then aa = qq or q×q = q^2
q^2 = (.20)^2 = .040 = 4%
Answer: 4%
Demonstrate how to use the balance that students will be using to measure the mass of the cube. Record the mass of the cube in grams (g). Show students how to calculate density<span> by dividing the mass by the volume. Point out that the answer will be in grams per cubic centimeter (g/cm</span>3<span>).</span>
Fats <span>store energy, provide insulation and protect our vital organs. Phospholipids are an essential component of the cell membrane and play a key role</span> in controlling the entry and exit of molecules and ions. Waxes are produced by many organisms as a protective layer against the outside environment, and can be used for example providing waterproofing to bird feathers. Steroids have various functions for maintaining homeostasis within organisms.<span> </span>
Answer:
Traits like white eye color in fruit flies are linked to the X chromosome.
Why:
Thomas Hunt Morgan was a scientist, he worked with Drosohilla and studied the sex chromosomes in fruit flies. In the course of his study he discovered that the white eye colour is recessive compared to the dominant red eye colour in the flies and that the white eye color gene is linked to the X sex chromosomes.
