The answer is (C) Replication

Though occasional errors could occur in cells during replication; the cells have error checking and proofing mechanisms that reduce the rate of error to one to several million replications in higher eukaryotes.
After all, one mismatch error during replication would not result in major effects. The others choices, however, have higher rates of causing genetic abnormalities.

LekaFEV [45]

Answer:

Muscular Dystrophy : 50%

Breast cancer: 50%

Explanation:

Muscular Dystrophy (linked to X):

1/2 (mother) x 2/2 (father) = 2/4 (50%) chance of having an affected child with MD

Breast cancer (autosomal dominant disorder):

1/2 (mother) + 0 (father) = 1/2 = 50% chance of having an affected child with breast cancer

The hypothalamus secretes corticotropin releasing hormone (crh) onto the anterior pituitary to stimulate secretion of
anastassius [24]
For Hypothalamo-Pituitary-Adrenal Axis of endocrine gland secretion, follow the root "CORTI" (C). This will be a great memory tool. Also, nearly all hypothalamic hormones that stimulate anterior pituitary secretion have the word RELEASING (hence "R" in their acronyms). So if asked what secretes CRH, GnRH, TRH, or GHRH... the answer will be the Hypothalamus because of the R.
Now... back to CRH... we're following the "C" for CORTI. What other endocrine hormone has C for CORTI??
ACTH = Adreno[Corti]coTropic Hormone
Which will then stimulate secretion of [Corti]sol (a glucocorticoid), amongst others from the cortex of the adrenal gland. Notice the [Corti] follows the whole pathway from Hypothalamus to adrenal Cortex: Hypothal. (CRH) --> Ant. Pituit. (ACTH) --> Adrenal Cortex (Cortisol)
Sorry this was so long-winded, but I was hoping to help you grasp a portion of how the Endocrine System works!
Good luck and hmu should you have any further Anatomy/Physiology questions.
