Hardy-Weinberg Equation (HW) states that following certain biological tenets or requirements, the total frequency of all homozygous dominant alleles (p) and the total frequency of all homozygous recessive alleles (q) for a gene, account for the total # of alleles for that gene in that HW population, which is 100% or 1.00 as a decimel. So in short: p + q = 1, and additionally (p+q)^2 = 1^2, or 1
So (p+q)(p+q) algebraically works out to p^2 + 2pq + q^2 = 1, where p^2 = genotype frequency of homozygous dominant individuals, 2pq = genotype frequency of heterozygous individuals, and q^2 = genotype frequency of homozygous recessive individuals.
The problem states that Ptotal = 150 individuals, H frequency (p) = 0.2, and h frequency (q) = 0.8.
So homozygous dominant individuals (HH) = p^2 = (0.2)^2 = 0.04 or 4% of 150 --> 6 people
Heterozygous individuals (Hh) = 2pq = 2(0.2)(0.8) = 0.32 or 32% of 150
--> 48 people
And homozygous recessive individuals (hh) = q^2 = (0.8)^2 = 0.64 = 64% of 150 --> 96 people
Hope that helps you to understand how to solve these types of population genetics problems!
Answer:
by measuring and examining a random sample of the population being analyzed.
Explanation:
The term "law" is a historical relic going back to Newtonian times, when after Newton's development of classical mechanics, it was thought that the workings of the universe were directly analagous to a perfectly constructed and perfectly predictable clockwork. That was turned on its head as a result of quantum mechanics, and modern scientists typically avoid use of the term "law" anymore because it is too dogmatic. Newton's "Laws" are still called that mainly for historical reasons now. What used to be called laws are now called theories.
Plants contain these things called chlorophyll, a green pigment that traps energy from sunlight. It absorbs red and blue light, which gives plants their green color. Hope this helps!
