Homozygous vs Heterozygous

Front

What does homozygous mean?

Back

An organism is homozygous when it has two identical alleles for a particular gene, such as AA or aa.

Front

What does heterozygous mean?

Back

An organism is heterozygous when it has two different alleles for a particular gene, such as Aa.

Front

What is an example of homozygous dominant?

Back

An example of homozygous dominant is BB, where both alleles are dominant.

Front

What is an example of homozygous recessive?

Back

An example of homozygous recessive is kk, where both alleles are recessive.

Front

What is an example of heterozygous?

Back

An example of heterozygous is Kk, where one allele is dominant and the other is recessive.

Front

How can you identify a homozygous dominant genotype?

Back

A homozygous dominant genotype can be identified by the presence of two uppercase letters, such as AA or BB.

Front

How can you identify a homozygous recessive genotype?

Back

A homozygous recessive genotype can be identified by the presence of two lowercase letters, such as aa or kk.

Front

How can you identify a heterozygous genotype?

Back

A heterozygous genotype can be identified by having one uppercase letter and one lowercase letter, such as Aa or Kk.

Front

What is the significance of alleles in genetics?

Back

Alleles are different versions of a gene that determine specific traits in an organism.

Front

What is the relationship between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable traits or characteristics.
