Explanation:
Alleles exhibit dominance over each other leading to the dominant one being express and the recessive one not expressed. Alleles are variants (different) genes that codes for a specific trait.
At Anaphase 1 homologous chromosomes separate leading to each being pulled to the opposite pole and the sister chromatids remain together while the homologs experience segregation.
Dominant trait is the one that is expressed. It usually exercise dominance over recessive trait until it is removed from the recessive trait and replaced with another recessive gene before it is expressed.
