1st conclusion: Organisms inherit two copies of each gene, one from each parent.
2nd conclusion: Organisms donate only one copy of each gene in their gametes.
Thus the two copies of each gene segregate or separate during gamete.

Answer:
25 and 21
Explanation:
if a homologous pair does not separate, then the homologous pair (when the spindle fibers are dragging it over to the other pole), then that chromosomes DNA will be the exact same as the paternal and maternals' DNA. During Meiosis I, there is the stage where the homologous pairs are lined up and pulled apart (where an exchange tends to happen), but if there pair doesn't mix, then the exact same DNA is duplicated, and thus, the same traits can be found in the daughter cell. If you are talking about an entire homologous pair being pulled over to one side of the nucleus, depriving the other side of a chromosomal pair, the daughter cells would then have 21 chromosomes, and the other one would have 25 chromosomes. The gametes, similarly, would have 21 chromosomes and 25 chromosomes.
Answer:
Second
Explanation:
Childbirth involves three stages:
The first stage starts with the onset of true labor and lasts until the cervix is completely dilated to 10 cm.
The second stage continues after the cervix is dilated to 10 cm until the delivery of your baby. This stage is called the "descent and emergence of the baby" stage. It involves the pushing by the mother and the delivery of your baby. Now that your cervix has fully dilated to 10 cm, this is the time for mother to help by pushing. This stage can last from 20 minutes to 2 hours.
The third stage involves the delivery of the placenta.
