Genetics

Front

What is a Punnett square?

Back

A diagram used to predict the outcome of a particular genetic cross or breeding experiment.

Front

What does it mean if an organism is diploid?

Back

It contains two alleles for each trait, one inherited from each parent.

Front

What is a chromosome inversion?

Back

A condition where a piece of a chromosome breaks away and is reinserted into the DNA 'upside down'.

Front

What is incomplete dominance?

Back

A type of inheritance where two alleles blend together to form a new phenotype.

Front

What is a pedigree?

Back

A diagram that traces the inheritance of a particular trait across generations.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their trait even if only one copy is present, while recessive alleles require two copies to express their trait.

Front

What are gametes?

Back

Reproductive cells (sperm and eggs) that contain half the number of chromosomes of the parent organism.

Front

What is co-dominance?

Back

A type of inheritance where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What is a genotype?

Back

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

Front

What is a phenotype?

Back

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