If the genotype for a trait is Tt, the t allele is called the allele, whose effect is masked by the other allele.
Question
If the genotype for a trait is Tt
, the t
allele is called the ____ allele, whose effect is masked by the other allele.
Solution
Definition of Alleles
In genetics, alleles are different forms of a gene that can exist at a specific locus on a chromosome. In the case of the genotype Tt, there are two alleles for a particular trait: T (dominant) and t (recessive).
Dominant and Recessive Alleles
- Dominant Allele: The allele that expresses its trait even when only one copy is present. In the Tt genotype, the T allele is dominant.
- Recessive Allele: The allele that only expresses its trait when two copies are present (homozygous). In this case, the t allele is recessive.
Conclusion
Thus, in the genotype Tt, the t allele is called the recessive allele, whose effect is masked by the dominant allele (T). The dominant allele will determine the phenotype (observable trait) in the presence of the recessive allele.
