Heterozygous
DNA is composed of long strings of nucleic acid sequences, but not all of them code for proteins. The ones that do are called genes. Alleles are different versions of a certain gene. For example, the gene that codes for blood type has 3 different alleles, A, B, and O. The genes that code for hair and eye color also have many different alleles.
Heterozygous
A heterozygous dominant gene is a gene that is more dominant in the gene pool but is made up of 2 diffrent traits passed from parent example: A heterzygous gene would be Tt for tall. The T stands for domintant trait as being tall and the t stands for the recessive trait short. All heterzygous means is that it is made up with 1 captial letter and 1 lowercase letter.
You get one allele, or a half of a gene, from each parent. That combination of alleles create a gene. You have different genes for each trait, but all genes are made from your parent's alleles.Read more: http://wiki.answers.com/How_do_you_inherit_genes#ixzz17AmtM8am
Homozygous
Heterozygous
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.

50% as there are two alleles per gene and four gametes are made from every undeveloped sex cell.
alleles are an expression of a gene given in chromosomes, which is coded by DNA, which in turn is made by the ribosomes , which in turn is made up of proteins. Short answer: they are made up of proteins.
Heterozygous
Chromosomes are made of tightly wound DNA and protein. Genes are found along the length of chromosomes. A gene is a segment of DNA that contains instructions for making a specific protein or proteins required by the body. Human beings have about 30,000 - 35,000 genes. We have two copies of each gene, but the copies can be slightly different. For example, the gene associated with cystic fibrosis has more than 1000 different variations. Different versions of the same gene are called its alleles, and everyone has two alleles for each gene. (Males have only one X chromosome, so they only have one copy of the genes located on the X chromosome.)
When the alleles are identical, the individual is homozygous for that trait. While if the pair is made of two different alleles.
A hybrid gene is a gene that is formed from a combination of two different genes. It can be made by recombinant DNA technology. Hybrid genes possess at least one characteristic of both the genes combined.
