A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
EastWind [94]

Answer:

A

AB

Explanation:

This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).

According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

The suprachiasmatic nucleus influences the release of melatonin by its effect on the ________________.
anyanavicka [17]

Answer:

Pineal gland

Explanation:

The suprachiasmatic nucleus is the paired nucleus made of about 1000 neurons each in the hypothalamus. The suprachiasmatic nucleus is involved in maintaining the endogenous clock or the internal clock.

The suprachiasmatic nucleus controls the circadian rhythm by controlling the amount of melatonin. The melatonin is produced by the pineal gland from the serotonin and tryptophan precursors.  The hypothalamus thus controls the amount of the melatonin by regulating the pineal gland.

Thus, Pineal gland is the correct answer.
