Answer: 49%
Explanation:
* long hair = P
* shirt hair = q using the Hardy-Weinberg equation for genotypic frequencies
* p^2 + 2pq + q^2 =1
*first use the equation to solve for the known value 18% hh
.18 = q^2
Square root .18 = q
So q = .42
* plug this allelic frequency in to p+q = 1
Which will give you the frequency of dominant alleles
1 - .45 = p So P = .58
Then just plug the P and q values found into the portion of the equation for heterozygous offspring.
2(.58)(.42)
Which is .49 or 49%
The entire population should be 33% homozygous dominant 49% heterozygous and 18% homozygous recessive.

<span>Severe
Several methods to assess the severity of psoriasis are available including Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA) for psoriasis, and the National Psoriasis Foundation Psoriasis Score (NPF-PS). In terms of body surface area, psoriasis is generally classified as mild when it affects less than 5% of the body, moderate when it affects 5-10%, and severe for >10%. Based on PASI, which includes a rating or score for the surface area of the body affected by psoriasis, the "Area Score" would be 2.

Answer:
Sperm-egg interaction
Explanation:
The formation of fertilization envelope is well-studied on the model system- sea urchin. It has been shown that, the fertilization envelope is formed after the initial sperm-egg interaction from the egg surface vitelline envelope and the paracrystalline protein fraction which is derived from cortical granules. Secretion from cortical granules, prevents polyspermy.
