Heredity questions part 1

Front

What did Mendel wonder about the pea plants?

Back

Mendel wondered why the pea plants had different characteristics.

Front

What sometimes happened to the traits of pea plants according to Mendel?

Back

According to Mendel, the traits of pea plants sometimes differed from their parents.

Front

What happens to Mendel's ratios if an F2 generation contains just 3 or 4 offspring?

Back

If an F2 generation contains just 3 or 4 offspring, the ratios might not match.

Front

In what conditions does a recessive trait appear?

Back

A recessive trait appears when both alleles are recessive.

Front

What does 'homozygous' mean?

Back

Homozygous means having the same alleles.

Front

What is a dominant trait?

Back

A dominant trait is one that is expressed when at least one dominant allele is present.

Front

What is an allele?

Back

An allele is a variant form of a gene that can produce different traits.

Front

What is the difference between genotype and phenotype?

Back

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

Front

What is the purpose of a Punnett square?

Back

A Punnett square is used to predict the genetic outcomes of a cross between two organisms.

Front

What does 'heterozygous' mean?

Back

Heterozygous means having two different alleles for a particular gene.
