Answer:

Tropic hormones

Explanation:

The damage probably occurred at the infindibular stalk or the pituitary stalk that links the hypothalamus to the pituitary glands. If this were to happen, then there would be no communication between the two endocrine glands and the chemical signals affected will be tropic hormones. This is because the releasing hormones from the hypothalamus will not be able to reach the pituitary glands to stimulate the release of the secondary hormones. Tropic hormones are hormones which have other glands as their targets for example Adenocorticotropin Hormone (ACTH) that regulates how the steroid hormone cortisol is released by the adrenal glands. The picture below shows the pituitary stalk linking the hypothalamus to the pituitary glands.

If someone with auburn hair has children with someone with red hair (but whose mother had black hair ) what are the genotype and
tensa zangetsu [6.8K]

The phenotype is - 75 % red and 25 %brown.

The genotype is hRhR - 25%

hBkhR - 50%

hBrhBk - 25%.

<h3><u>Explanation:</u></h3>

The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.

Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be

Father - hBr and hR

Mother - hBk and hR

So, the probable combinations are hBrhBk, hBrhR and hBkhR.

The frequency of the combinations are 25%, 25% and 50% respectively.

The phenotypic ratio will be red : brown as 3:1.
