GENOTYPE- HETEROZYGOUS-HOMOZYGOUS-DOMINANT RECESSIVE

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, representing the alleles inherited from its parents.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a specific gene, one inherited from each parent.

Front

What does homozygous dominant mean?

Back

Homozygous dominant means having two identical dominant alleles for a specific gene.

Front

What does homozygous recessive mean?

Back

Homozygous recessive means having two identical recessive alleles for a specific gene.

Front

What is a dominant allele?

Back

A dominant allele is an allele that expresses its trait even when only one copy is present in the genotype.

Front

What is a recessive allele?

Back

A recessive allele is an allele that only expresses its trait when two copies are present in the genotype.

Front

Give an example of a heterozygous genotype.

Back

An example of a heterozygous genotype is Aa, where 'A' is a dominant allele and 'a' is a recessive allele.

Front

Give an example of a homozygous dominant genotype.

Back

An example of a homozygous dominant genotype is AA, where both alleles are dominant.

Front

Give an example of a homozygous recessive genotype.

Back

An example of a homozygous recessive genotype is aa, where both alleles are recessive.

Front

What is the relationship between genotype and phenotype?

Back

The genotype determines the phenotype, which is the observable physical or biochemical characteristics of an organism.
