Homozygous or Heterozygous?

Front

What is a Homozygous genotype?

Back

A genotype consisting of two identical alleles for a particular gene (e.g., AA or aa).

Front

What is a Heterozygous genotype?

Back

A genotype consisting of two different alleles for a particular gene (e.g., Aa).

Front

What does the letter 'G' represent in genotypes?

Back

It represents an allele, which can be dominant or recessive.

Front

What does the letter 'P' represent in genotypes?

Back

It represents an allele, which can be dominant or recessive.

Front

If a genotype is 'GG', what type is it?

Back

Homozygous.

Front

If a genotype is 'Hh', what type is it?

Back

Heterozygous.

Front

What is the significance of dominant alleles in genotypes?

Back

Dominant alleles can mask the effect of recessive alleles in a heterozygous genotype.

Front

What is the significance of recessive alleles in genotypes?

Back

Recessive alleles only express their traits when in a homozygous condition.

Front

How can you identify a homozygous genotype?

Back

By checking if both alleles are the same (e.g., AA or aa).

Front

How can you identify a heterozygous genotype?

Back

By checking if the alleles are different (e.g., Aa).
