they are found on different chromosomes. *
No, a homozygous individual has two identical alleles for a particular trait, while a hybrid individual has two different alleles for the same trait.
When the alleles are different the organism is heterozygous for that trait. Another way of putting it is to say the genotype is heterozygous for that trait. The dominant allele will be seen in the phenotype ie what is displayed.Most traits are governed by more than one pair of alleles.
Particular Versions of Genes are called Alleles - one way they differ is that some alleles are termed to be dominant while others are termed to be recessive.
Actually, it is the recessive.................................................................UR WELCOME! :)
Alleles of a gene are found at the same locus on homologous chromosomes, not on homologous mitochondria. Mitochondrial DNA is typically inherited maternally and is not organized in homologous pairs like nuclear DNA. Instead, there are multiple copies of the mitochondrial genome within each mitochondrion, and variations or mutations in this DNA can occur, but they do not represent alleles in the same way as nuclear genes. Therefore, the concept of alleles at a locus is primarily applicable to nuclear DNA rather than mitochondrial DNA.
Alleles are pairs of genes that determine a specific trait in an organism. Each parent contributes one allele, and the combination of alleles determines how the trait is expressed. If the alleles are the same (homozygous), the trait will be expressed in a certain way. If the alleles are different (heterozygous), one allele may be dominant and determine the trait's expression, while the other may be recessive and not expressed.

"now that it how the single gene trait is controlled"by the way stop cheating and seeing the answers online
Heterozygous alleles are used to describe the 'parents' when creating a test cross chart. When completing a test cross there is more than comparing alleles, you are really comparing genetics. Heterozygous YY or yy versus Homozygous Yy, is just the first to consider.
Individual versions of genes are called alleles. Alleles are variations of a gene that can result in different traits or characteristics in an organism. Each individual inherits two alleles for each gene, one from each parent.
There are many ways alleles are determined for diff-rent traits and one way is by joining both recessive and dominantalleles together.
Two copies of the recessive allele are the only way a recessive trait is expressed phenotypically.
yep

A genotype in which both alleles are the same is called homozygous. This means that the individual has two identical alleles for a particular gene (e.g., AA or aa). Homozygous genotypes can be either homozygous dominant (both alleles are dominant) or homozygous recessive (both alleles are recessive).
Neither of the parents will be affected. There may not be any one with he disease in either of the parents families (or there might be). Since each parent is a carrier and has a 50/50 chance of passing one copy of the gene to each child 1/4 of the children will not get the gene, 1/2 will be carriers (1 copy) and 1/4 wil be affected (2 copies).
