Genes (Dominant (Def- A trait that is shown whenever it exist in the gene.…
Genes
-
Punnet Squares
-
Example- If both parents were heterozygous,then, according to the punnet square, the child would have a 75% chance to show the dominant trait, and a mere 25% chance to show the recessive.
Alleles
-
Def-Alternate form of a gene that holds a trait, the allele can be either dominant or recessive. There are 2 in each gene.
-
Phenotype
