During meiosis, chromosome pairs are split apart and distributed into cells called gametes. Each gamete contains a single copy of every chromosome, and each chromosome contains one allele for ...

Similar genes occupy the same position on both chromosomes in the pair. Alleles can be dominant or recessive. Dominant alleles will be expressed even if a recessive allele is present. Recessive ...

This includes which allele (if either) is fixed ... If monogamy is enforced, once a mating pair has been created (e.g., individuals 2 and 31), neither individual can be paired with a different ...

Each gene might have different forms, and these are called alleles. The gene for eye colour has an allele for blue eye colour and an allele for brown eye colour. For any gene, a person may have ...
