Back

Gregor Mendel.

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype consists of two identical dominant alleles, represented as 'AA'.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype consists of one dominant and one recessive allele, represented as 'Aa'.

Front

What is a recessive trait?

Back

A recessive trait is a trait that is only expressed when an individual has two copies of the recessive allele.

In pea plants, what does the 'T' allele represent?

Back

The 'T' allele represents the dominant trait for tall stems.

Front

In pea plants, what does the 't' allele represent?

Back

The 't' allele represents the recessive trait for short stems.

What is the expected phenotype ratio from a cross between two heterozygous tall pea plants (Tt x Tt)?

Back

The expected phenotype ratio is 3 tall : 1 short.

Front

What is the expected genotype ratio from a cross between two heterozygous tall pea plants (Tt x Tt)?

Back

The expected genotype ratio is 1 TT : 2 Tt : 1 tt.
