Huntington's disease is a dominant condition with late age of onset in humans. if one parent has the disease, what is the probability that his or her child will have the disease

For the sake of calculation, let us assume that the diseased parent is homozygous for the Huntington’s disease. Homozygous meaning that the diseased parent’s gene carries two copies of the same allele.

Since only 1 of the 2 parents has the disease, then the probability of contracting it is ½.

1/2

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
