What determines the genotypes of organism?
The genotypes of an organism are determined by the combination of alleles they inherit from their parents during sexual reproduction. Each parent contributes one allele for each gene, resulting in a unique genetic makeup for each individual. Gene mutations and genetic recombination can also influence an organism's genotype.
How many chromosomes are in a normal human being?
Technically we have 23 chromasomes (you will never hear a paper refer to chromasome 24 or 37 etc), but we have two copies of each, bringing the total to 46. This includes the sex chromasomes.
How many chromosome' s do people have in their gametes?
People have 23 chromosomes in their gametes – 22 autosomes and one sex chromosome. This is the result of a process called meiosis, which halves the number of chromosomes in a cell to produce gametes with half the genetic material.
What is a reccesive gene?
A recessive gene is a gene that is only expressed if an individual has two copies of it, one inherited from each parent. In the presence of another dominant gene, the recessive gene's trait is not expressed.
How do the daughter cells after meiosis compare to the parent cell?
1. primary spermatocyte (dipolotid (46)) ------1st meiotic division------ produce: 2 secondary spermatocytes (haploid (23)) ------2nd meiotic division-------- Producing four spermatids (haploid (23)) so the difference is that in the begnning u have a dipoloid cell with 46 chromosomes, and in the end u wil have a haploid cell with 23 chromosomes that in the case are ready to meet the egg, and produce a zygote (diplotid, with 46 chromosomes) that wil develop to be a child.
What words have the root word chroma in it?
soul life Carabanna chromatic Chromasome
Is huntington's disease a chromosome disorder?
Yes- it is transmitted from parent to child by a chromasome.
Is Down syndrome caused by single or multiple genes?
it's the duplication of the 21st chromasome
Because the gene for red-green color blindness is located on the X chromosome it is normally not possible for a?
Females are rarely colourblind because they have 2 X chromasomes. They would therefore have to have inherited the gene from both parents (X from the mother and X from the father). As males have only 1 X chromasome and there is no corresponding place on the Y chromasome for the matching allele (gene), men who inherit the gene on the X chromasome (from their mothers) are automatically colourblind.
How does the chromosomes in a nerve cell differ from those in a sperm cell?
The sperm cell is haploid (has half as many chromasomes as the diploid nerve cell)The sperm cell can contain more mutations (depending on the age of the man, this is the basis of anticipation)The sperm cell's chromasome has undergone recombination (I'm assuming you know what that is)

Why are my six feet pubic hair long and smelly?
well 8i think this could be a hereditary condition called gingerism in which the chromasome for pube legnth is crossed over with the smell gene on the 18th chromasomje creating this effect sollution== wash, deoderize or shave ur smelly areas if this problem continues after you have done all three you have cancer of the pubism

Is it true that women have some protection from genetic disease because they carry only x chromosomes?
Yes, women have two X chromosomes which provides them with a backup copy of certain genes. This can offer some protection from genetic diseases that are caused by mutations in genes on the X chromosome, as women have a second copy that may compensate for any abnormalities.
Red-green color blindness is a human genetic disorder cause by?
Color blindness is a sex-linked genetic disorder. The reason that it is more prevalent in males is because the disorder is linked the the X-chromasome. If a male inherits an X chromosome that is defective, then they will be color blind. However, a female has two X chromosomes which means she can receive a defective chromosome and only be a carrier of the mutation. If she receives two defective x chromosomes, she will be colorblind.
Difference between the chromosomes of a person with Down syndrome and a person without Down syndrome?
An individual with Down Syndrome has the presence of all or part of an extra 21st chromosome.
How do retarded people get retarded?
Different ways. Doctors are able to assign a specific cause in only about 25% of the cases. In general, something happened to the baby before the baby was born. It may have been an infection, that the mother was exposed to harmful chemicals, a genetic problem, or some type of physical injury to the unborn child. A few of the things known to cause problems in mental development include Fragile X chromasome (genetic) Measles and HIV (infection) exposure to lead (environmental) and malnutrition. This is a very short answer to a very LARGE field of study.
