DOMINANT TRAITS :-
Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. (In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). ... (In genetic terms, a recessive trait is one that is
phenotypically expressed only in homozygotes).
RECESSIVE TRAITS :-
A recessive trait is a trait that is expressed when an organism has two recessive alleles, or forms of a gene. ... Every organism that organizes its DNA into chromosomes has two alleles for a trait, one from their mother and one from their father. Alleles can be dominant or recessive.
