Through meiosis, a process which takes place in the gonads (testis/ovaries).

Normal body cells divide, creating 2 exact copies of each other, however when a sex cell divides it creates 4 cells each of them having half the amount of DNA. Therefore when the sperm meets the egg, it's half mom's DNA and half dad's.

High School grades do -- and don't -- affect one's ability to work. On the one hand, grades can reflect effort and knowledge. But, on the other hand, learning styles and many other factors can affect grades-- even when a person is intelligent and hard-working. As an example, the death of a parent can result in failing grades for a good year or so.

So grades do not impact the ability to work, as long as the person is hardworking and qualified to do the job for which they are hired. As an example, if you failed Spanish you probably shouldn't try to be a Spanish Interpreter.

They may be called several things. They could be called Chromosomes (however these are when the genetic information has been aggregated into bodies (usually resembling an X). It can be called DNA (meaning deoxyribonucleic acid) which is the long strand of information made of up base pairs which resembles a twisted ladder. A small segment of that ladder which produces only one protein may be called a Gene. (from whence we get the term genetics).

When DNA is being used to make pieces of the cell and produce stuff in genera, it is transcoded into RNA (Ribonucleic Acid) which is a temporary form of the genetic information which can be taken from the nucleus of the cell where the DNA is stored and turned into protein elsewhere. This form of RNA is known as Messenger (m)RNA.

containing genetic information: Chromatin condenses to form chromosomes. These distinct, threadlike structures contain the genetic information or DNA.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

Exercising will get rid of the love handles. A lot of ab work outs. Gaining weight, you may gain weight by working out because muscle wieghts more than fat. There are meal plans that will help you gain weight, but I don't know of any myself.

A mixture of weight training and cardio exercises will develop muscle and help burn excess fat, increasing weight and reducing those dreaded love handles. Make sure you have a proper weight training programme for maximum results and watch that diet.

cross over happens during meiosis. what you have to keep in mind is meiosis id totally random. its like throwing a a blue and red deck of cards in the air and picking up RANDOMLY 23 of them. crossover happens in prophase 1. after the DNA organizes and the DNA copies, the chromotid tips touch- 46 pairs are touching, 23 of the 46 chromosomes touch/ cross over, remember this is completely random.also keep in mind that it is the mothers chromotid tip connecting with the fathers cromotid tips. now the reason this causes genetic variation is because everything is random and some traits are dominant and others a recessive. now the reason mutations cause genetic variations is because when the RNA copies wrong it cuases a mutation witch means somthing difforent type of cell has been made. if this new "mutated" cell gets into the gene pool then you have a new species. this = evolution.
