Hemizygous - has 1/1 copy of the allele Heterozygous - has 1/2 copies of the allele
Homozygous - has 2/2 copies of the allele

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.
Alleles of a gene are found at the same locus on heterologous chromosome true or false?
False. Alleles of a gene are found at the same locus on homologous chromosomes.
Why do the chromosomes in a homologous pair differ from one another?
They have the same length and gene locus but differ in terms of alleles. An allele is a form of a gene, differing from other alleles of the gene by a few bases at most and occupying the same locus as the other alleles of that gene. The gene locus is the position of a gene on a chromosome. Hope that helped! They have the same length and gene locus but differ in terms of alleles.

What is xp21 gene?
Dystrophin gene / Xp21 gene / DMD gene: Found at locus Xp21 of the X chromosome, this is why it's called the (Xp21 gene) It's the gene responsible for Duchenne muscular dystrophy(DMD) when mutated, this is why it's called (DMD gene)
Describe where the human SRY gene resides and its significance?
It is the gene on the Y chromosome important for male development.
What do you call the physical location of a gene?
The specific term is gene locus. If the exact location is known then there is more specific terminology that refers to the chromosome number whether the locus is on the short (p) or long (q) arm of the chromosome and it's specific location based on band and sub-band location.

What is the meaning of the word locus?
The word "locus" refers to a specific place or position. It can also be used to describe a gene's physical location on a chromosome.
What name is given to the specific location of a gene on a chromosome?
The specific location of a gene on a chromosome is called it's locus.
What is the definition of locus?
The particular site where a gene is found on a chromosome.
Alleles of a gene are found at the same locus on heterologous chromosome true or false?
False. Alleles of a gene are found at the same locus on homologous chromosomes.
What is a locus?
LociA locus (plural loci) is the position on a chromosome where a gene is found. A useful analogy would be the address - 'Gene for brown eyes' is the name, '23rd gene' is the house number, 'Chromosome 4' is the street. (these are not necessarily true for this gene)A link can be found below.
What is the name given to genes that have more than two alleles?
Polymorphic locus or polymorphic gene. Many geneticists use the term locus (plr. loci) for a gene (i.e. section of a chromosome)
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 a monomorphic locus?
I believe that it refers to a site in the chromosome which contains a gene that translates to a feature which appears identical in both males and females of the species.
