For just random assortment, there are 2 to the power of the number if pairs of chromosomes. In humans, it's 2 to the 23 power. Recombination and random fertilization create even more variations but can not be calculated.
two tall genes or one tall gene and one short gene
when genes cross over during meiosis, then split they from genes that differ.
genetic variation
Offspring inherit a combination of genes from both parents, but this doesn't necessarily mean they maintain the exact gene combinations of either parent. Genetic recombination and independent assortment during meiosis result in unique combinations of genes in offspring. These genetic variations contribute to the diversity within a species.
No, mutations are not the only way to add new genes to a gene pool. Gene flow, which involves the movement of genes between populations, can also introduce new genetic variation. Additionally, genetic recombination during sexual reproduction can shuffle existing genes to create new combinations.
genetic drift is the change in genes due solely to chance.bottleneck effect and founder's effect are both examples of how chance effects the genes.
Humans typically have two copies of each gene, one inherited from each parent. This pairing of genes allows for genetic diversity and a variety of possible gene combinations. Some genes may have multiple copies or variations, but in general, humans have two copies of most genes.
Genes usually come in pairs because an organism can inherit a given gene from both parents. Six genes is not a lot, that would be a small portion of a genome.

A given gene is present on exactly two chromosomes in a somatic cell.
A collaborative gene refers to a gene that works together with other genes or gene products to perform a specific biological function. These genes often interact to regulate various cellular processes and pathways. Collaboration among genes is essential for the development and maintenance of organisms.
