Additional copies of a gene ON A CHROMOSOME causes cellular problems. The number of chromosomes is fixed for a particular organism. For example, humans have 46 chromosomes or 23 pairs of chromosomes. Each chromosome has segment of the DNA known as genes and is the characteristic of that chromosome. Any alteration such as addition or removal of genes causes cellular problems that lead to changes in phenotypic expressions.
To conserve energy, the genes in E coli are ONLY ACTIVE WHEN NEEDED.
Gene regulation refers to the turning on and off of genes. Gene regulation makes it possible for cells to produce specific proteins only when they are needed. In E coli for instance, the necessary enzyme for the metabolism of lactose is only turned on only when lactose is present, this is done as mean of preserving energy.
There is a 1:4 chance of getting JjQq. The parent JjQq can produce four genotypes: JQ, Jq, jQ, and jq. the parent JJQq can produce two genotypes: JQ and Jq. When we do a punnett square: JJQQ, JJQq, JjQQ, JjQq, JJQq, JJqq, JjQq, and JjqqThere are two JjQq. Two out of eight is one out of four.
I think the haploid number would be....

A comprehensive match requires sequencing the entire genome; disporiving a match just requires finding any discrepancies at all. In other words, as soon as you find something different, you have proven innocent. To prove guilt you have to go all the way through.
