WebLinkage explains why certain characteristics are frequently inherited together. For example, genes for hair color and eye color are linked, so certain hair and eye colors tend to be inherited together, such as blonde hair with blue eyes and brown hair with brown eyes. What other human traits seem to occur together? Weba hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian genetics), it would mean that it has two different alleles (ex. AB or A^1 B^1).

WebInheritance is possible because of chromosomes. These chromosomes come in pairs - one from mom and one from dad - so they’re called homologous chromosomes. Each chromosome has genes, which are segments of DNA that carry genetic information for a specific trait. And different versions of the same gene are called alleles.
