Understanding Dominant vs Complete Dominance in Genetics
Explore the key differences between dominant and complete dominance relationships in genetics.
224 views
Dominant and complete dominance relationships describe different genetic interactions. In a dominant relationship, one allele masks the effect of another, but both alleles can still be expressed to varying degrees. In a complete dominance relationship, one allele entirely masks the presence of another, leading to one observable trait, while the other remains completely hidden in heterozygous conditions.
FAQs & Answers
- What does it mean for an allele to be dominant? A dominant allele is one that can mask the effect of another allele, resulting in a specific observable trait.
- How does complete dominance differ from incomplete dominance? In complete dominance, one allele masks the other entirely, while incomplete dominance results in a blending of traits.
- Can dominant and recessive traits be expressed together? In a dominant relationship, both traits can be expressed to varying degrees, whereas in complete dominance, only the dominant trait is visible.
