The correct answer for the question that is being presented above is this one: "TRUE." <span>Teeth patterns in animals and thorns in plants are examples of characteristics that a taxonomist might observe for keying. The statement show a positive and true idea.</span>
The answer would be choice B.
This is because homeostasis is the regulation of body temperature and sweating, caused by the respiratory system, is a way the body maintains homeostasis.
Answer:
are there any sentences to choose from
Answer:
a. purple allele (C) = 0.609, pink allele (c) = 0.391
b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476
Explanation:
Given -
Purple flowers - 847
Pink flowers - 153
The frequency of recessive genotype i.e
![q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\](https://tex.z-dn.net/?f=q%5E%202%20%3D%20%5Cfrac%7B153%7D%7B1000%7D%20%5C%5Cq%5E%202%20%3D%200.153%5C%5C)
Frequency of recessive allele i.e q is equal to
![q = \sqrt{0.153} \\q = 0.391](https://tex.z-dn.net/?f=q%20%3D%20%5Csqrt%7B0.153%7D%20%5C%5Cq%20%3D%200.391)
As per hardy Weinberg's first equilibrium equation -
![p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609](https://tex.z-dn.net/?f=p%20%2B%20q%20%3D%201%5C%5Cp%20%3D%201-q%5C%5Cp%20%3D%201-0.391%5C%5Cp%20%3D%200.609)
Frequency of purple homozygous species
![= p^2\\= 0.609^2\\= 0.371](https://tex.z-dn.net/?f=%3D%20p%5E2%5C%5C%3D%200.609%5E2%5C%5C%3D%200.371)
Number of purple homozygous species ![= 0.371 * 1000= 371](https://tex.z-dn.net/?f=%3D%200.371%20%2A%201000%3D%20371)
Number of pink homozygous species ![= 0.153 * 1000= 153](https://tex.z-dn.net/?f=%3D%200.153%20%2A%201000%3D%20153)
Heterozygous species is equal to
![(1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476](https://tex.z-dn.net/?f=%281-0.371-0.153%29%2A%201000%5C%5C%3D%200.476%20%2A%201000%5C%5C%3D%20476)
Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes sperm and eggs.
