What is a dominant trait?

Back

A dominant trait is a characteristic that is always expressed in the phenotype when at least one dominant allele is present.

Front

What is a recessive trait?

Back

A recessive trait is a characteristic that is only expressed in the phenotype when two recessive alleles are present.

Why did Mendel choose pea plants for his experiments?

Back

Mendel chose pea plants because they grow quickly, have easily observable traits, and can be easily cross-pollinated.

Front

What is an allele?

Back

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

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene.

Front

What is the genotype?

Back

The genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is the phenotype?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is Mendel's Law of Segregation?

Back

Mendel's Law of Segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is Mendel's Law of Independent Assortment?

Back

Mendel's Law of Independent Assortment states that alleles for different traits are distributed to gametes independently of one another.
