Where is location of different alleles of the same gene?
One of the different alleles would be at the same gene locus on each of the paired chromosomes.
What is the difference between a factor and an allele?
A locus is a particular location or a marker on a chromosome. It can be a gene but really only needs to be an identifiable location on the chromosome. Alleles differ in that they refer to a particular sequence of DNA at a given locus. The distinction from loci is that multiple alleles can exist for the same locus. http://www.informatics.jax.org/silverbook/glossary.shtml
What is the number of alleles in a gene?
An allele of a gene resides on a chromosome; as there are typically two chromosomal copies in an individual Cell, there are typically two alleles of each and every gene in the individuals genome, or its genetic complement.
When new cells are formed through the process of mitosis what does the number of chromosomes do in the new cells?
I don't know if this is what you are looking for but.... Each gene has two alleles. Alleles are forms of a chromosomes. Every cell has two chromosomes or alleles for each gene. Is that what you were looking for?
Are all genes passed on from each parent to each child?
Only half of each parent's alleles are passed to their children. This means that parent 1 who is Aa at one gene locus will only pass A or a on to each offspring. Parent 2 may be AA, aa or Aa and will also only pass one allele on to each offspring.
Where is location of different alleles of the same gene?
One of the different alleles would be at the same gene locus on each of the paired chromosomes.
How many alleles do your gametes have?
Gametes should contain one allele for each gene locus. This means that gametes will have one allele for each of the genes on the chromosomes they are carrying. It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles.

How many copies of a gene does each somatic cell have?
One. A gamete is a haploid cell containing one copy of each chromosome (23 in humans). Each chromosome contains one copy of each gene. Therefore, a gamete contains one copy of each gene.
Each gamete gets one gene from each trait?
Each reproductive cell (gamete) is 1N (the haploid chromosome count) which means it has a single allele for a genetic trait at each gene locus...this is based on the assumption that the trait is controlled at a single site. Polygenic traits, those controlled or modified at more than one locus, will have multiple alleles for a trait.
About how many genes do horses have?
An individual Thoroughbred cannot have more than two different alleles for each gene locus, one on each chromosome. How many alleles are available at a certain gene locus is variable based on what the gene controls and how many alleles are available and their frequency in the population.
What are examples for the word allele?
The term allele is often used interchangeably with the word gene. Allele/gene is used for the variations seen at each gene locus for a trait on the homologous chromosome pair. For example: If there are three alleles for a trait only two of the alleles will be represented in the genotype of any one individual. The alleles for basic blood types A, B and O are examples. In general the term allele is not used interchangeably with gene in conjunction with the terms locus or loci..therefore Gene locus or gene loci but not allele locus or allele loci.
How many alleles can occur at a microsatellite locus?
Most alleles are either present or absent, which gives two choices. Those which are not, say for skin color of mixed-race heritage, can exhibit a large number of possibilities, and though the exact count might be difficult to determine, it is of course finite.
If the male parent is heterozygous for a trait what alleles for each sperm cell possibly have?
each sperm cell could either have the dominant or the recessive allele for that trait
How many alleles does a body cell have for each trait?
Every sex cell has one allele for each trait. after meiosis, pairs of chromosomes separate and alleles for each trait also separate into different sex cells.
What is the seperation of alleles?
The law of segregation of alleles, the first of Mendel's laws, stating that every somatic cell of an organism carries a pair of hereditary units (now identified as alleles) for each character, and that at meiosis the pairs separate so that each gamete carries only one unit from each pair. This is called the law of segregation.
What is the relationship between genes and alleles?
The gene loci are the sites where the alleles reside on the DNA strand. Alleles at the same gene locus on each chromosome pair will determine the phenotypic expression of that gene pair. Of course this explanation is incomplete when more complex interactions between alleles come into play
