What is a homozygous recessive allele?

Back

A homozygous recessive allele is a pair of identical alleles for a trait that are both recessive, represented as 'tt'.

Front

What is the definition of genotype?

Back

Genotype refers to the exact genetic makeup of an organism, such as RR, Tt, or PP.

Front

What is the role of a dominant allele in a heterozygous genotype?

Back

In a heterozygous genotype, the dominant allele takes over in the phenotype.

Front

What is the difference between genotype and phenotype?

Back

Genotype is the genetic makeup of an organism, while phenotype is the observable physical traits.

Front

What does the term 'phenotype' refer to?

Back

Phenotype refers to the observable characteristics or traits of an organism, such as black hair.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype consists of two different alleles for a particular gene, such as 'Tt'.

Front

What is a homozygous dominant allele?

Back

A homozygous dominant allele is a pair of identical alleles for a trait that are both dominant, represented as 'TT'.

Front

What is the significance of the allele 'A' in genetics?

Back

The allele 'A' can represent a dominant trait in a genotype, influencing the phenotype.

Front

What does it mean if an organism has the genotype 'AA'?

Back

If an organism has the genotype 'AA', it is homozygous dominant for that trait.

Front

What is the phenotype of an organism with the genotype 'Tt'?

Back

The phenotype of an organism with the genotype 'Tt' will display the dominant trait.
