Genetics/Heredity

Front

What is the phenotype of an organism?

Back

The phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What does DNA stand for?

Back

DNA stands for deoxyribonucleic acid, which is the molecule that carries the genetic instructions for life.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the physical expression of those genes.

Front

What are dominant and recessive alleles?

Back

Dominant alleles are expressed in the phenotype even if only one copy is present, while recessive alleles are only expressed if two copies are present.

Front

What is a trait?

Back

A trait is a characteristic or feature of an organism, which can be inherited from its parents.

Front

What is heredity?

Back

Heredity is the passing of traits from parents to offspring through genes.

Front

What is a Punnett square?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

What is self-pollination in plants?

Back

Self-pollination is the process where a plant's pollen fertilizes its own ovules, leading to the production of seeds.

Front

What is a homozygous genotype?

Back

A homozygous genotype has two identical alleles for a particular gene, such as AA or aa.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has two different alleles for a particular gene, such as Aa.
