How does the amount of genetic material compare between sex cells and body cells?

Half. A somatic cell contains 2n and a gamete contains just n, where n is the number of chromosomes, which varies among species.
Stating the obvious, if an animal has to have 2n, and is formed via sexual reproduction then mathematically speaking, both gametes have to only have n. The survivability of a 3n animal (of a species/generation that is 2n) is low or impossible, and will usually die, sometimes even before being born. Such errors in division do occur, and they are naturally miscarried.

Why must a cell reduce the amount of genetic material during meiosis?
So that it can separate into more cells.
Why are chromosomal translocations often not a problem?
Because if the same amount of genetic material is present, then the individual has all the correct material for normal development. In this case it is called a "balanced translocation" or BT. If there is extra genetic material (duplications) or of some of it is missing (deletions) then the individual most often has problems relating to physical and/or mental development. This is known as an "unbalanced translocation" or UBT. Duplications and deletions of genetic material also often result in miscarriage of the embryo. If the embryo survives, it very often has severe complications. So in cases of repeated miscarriage, it is important for the parents be be tested for possible chromosome issues.
What is definition of britleness for testing material?
A material will be graded as brittle when it breaks with only a small amount of strain. Its brittleness is based on the amount of deformation used to break the material.
What is genetic gain?
is the amount of increase in performance that is achieved through artifical genetic improvement programs. This is usually used to refer to the increase after one generation has passed.
What genetic disorder causes a defective gene that makes proteins necessary to pump chloride in and out of cells?
Cystic Fibrosis
What has happened to the amount of genetic material in a cell after the S phase of interphase?
it doubles
Do sister chromatids have half the amount of genetic material as the original?
yes they do
What is the amount of variation in genetic material of all members in a population called?
Allele frequency.
How is genetic info held in the nucleus and and what in important about the amount in the sperm cell?
The sperm cell usually contains half the number of the genetic material.
Why must a cell reduce the amount of genetic material during meiosis?
So that it can separate into more cells.
Which processes result directly in the formation of cells with half the amount of genetic material that is characteristic of the species?
Process 4 and 2
What is the end results of sexual reproductions of meiosis?
A gamete is formed, which is a haploid (n=1): having half the amount of genetic material.
How do the cock and the hen pass on their characteristics to the chick?
With their genetic material. The chicks have copy, and therefore express a certain amount of the parents traits.
How compared to mitosis the process of meiosis results in?
greater amount of genetic material per cell
What is and egg cell?
Gametes! They contain half the amount of genetic material that body (somatic) cells contain. BAsed on this fact, they are called haploid.
