Answer D .) to send a two-person spacecraft into orbit for two weeks.

It was a bridge program between Mercury and Apollo.​

Gemini in Latin means "twins" or "double", which reflected that the spacecraft would hold two astronauts.​

To demonstrate endurance of humans and equipment in spaceflight for extended periods, at least eight days required for a Moon landing, to a maximum of two weeks.​

What three processes lead to variation among offspring that have the same two parents?
beks73 [17]

Explanation:

Genetic variation in offspring during sexual reproduction is caused by

  • crossing over
  • independent assortment
  • randomized fertilization

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

  • crossing over:  the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
  • independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
  • randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

The quintessential (most basic/ most important) moment of fertilization of the egg by the sperm cell occurs when
DedPeter [7]

The answer is pronuclei. A pronuclei is the state of the nucleus of either the sperm or the ovum after the sperm has entered the ovum but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane of the sperm pronuclei dissolves hence leaving no barrier for the two genetic materials to combine.
