Im not sure the answer is there
Answer: If this population were in equilibrium and if the sickle-cell allele is recessive, the proportion of the population susceptible to sickle-cell anemia under typical conditions should be 0.20
Explanation: Hardy-Weinberg law provides an equation to relate genotype frequencies and allele frequencies in a randomly mating population. The equation is;
p² + 2pq + q² = 1
For 2 alleles such as A and a, where
p² = homozygous dominant
q² = homozygous recessive and
2pq = heterozygous
From the question, it is said that the sickle-cell allele (SS) constitutes 20% (that is, 20/100) of the hemoglobin alleles in the human gene pool and it is also said to be the homozygous recessive allele.
Therefore, q² = 20/100 = 0.20
The correct answer is: A. Nondisjunction
Let me know if this helped :)

Answer: b. anterior.
Explanation:
Hypothalamic releasing and inhibiting hormones control the release of other hormones from the pituitary gland and they are secreted by neurons. They enter the anterior pituitary through blood vessels and to do this, <u>there is a bridge of capillaries that connects the hypothalamus, which is a part of the brain, to the anterior pituitary gland</u> and it is called the hypophyseal portal system. This system allows the hypothalamic hormones to be transported to the anterior pituitary without entering the systemic circulation.
So, the secretion of the hormones from the pituitary gland is regulated by releasing and inhibiting hormones from the hypothalamus. The six hormones produced by the anterior pituitary gland are:
- luteinizing hormone (LH)
- follicle-stimulating hormone (FSH)
- thyroid-stimulating hormone (TSH)
- adrenocorticotropic hormone (ACTH)
- prolactin (PRL)
- growth hormone (GH)
