Gametes come in two forms, sperm (the 'male' gamete) and eggs (the 'female' gamete). Each of these gametes only contain half the number of chromosomes that the main organism's cells have, because these cells combine both male and female to create new organisms.
Different versions of the same gene are called
alleles are the various types of options that is chosen by the gene. The gene is the segment of DNA that codes for the protein. Genes are found on chromosomes. Chromosomes contain multiple genes.
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.
50% as there are two alleles per gene and four gametes are made from every undeveloped sex cell.
segergation
Normal gametes should contain one allele from each gene.
Alleles
alleles
They are called alleles. Alleles determine things such as your eyecolor, height, fingerprints, etc.
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.
Depends on the gene. Can be as few as 2, or more than that. Height, hair colour etc have multiple alleles.
Gametes come in two forms, sperm (the 'male' gamete) and eggs (the 'female' gamete). Each of these gametes only contain half the number of chromosomes that the main organism's cells have, because these cells combine both male and female to create new organisms.

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.
