Heredity (Mendelian, Vocab, Punnetts)

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 does phenotype mean?

Back

Phenotype refers to the observable traits or characteristics of an organism, such as color, size, and shape.

Front

What does genotype mean?

Back

Genotype is the genetic makeup of an organism, representing the alleles inherited from its parents.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles only express their traits when two copies are present.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene, either dominant or recessive.

Front

What does heterozygous mean?

Back

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

Front

If 'G' is gray fur and 'g' is white fur, what is the phenotype of a rabbit with genotype 'Gg'?

Back

The phenotype of a rabbit with genotype 'Gg' is gray fur.

Front

What is the expected phenotypic ratio from a monohybrid cross of two heterozygous parents (Gg x Gg)?

Back

The expected phenotypic ratio is 3:1 (3 gray fur : 1 white fur).

Front

What is a test cross?

Back

A test cross is a breeding experiment used to determine the genotype of an organism with a dominant phenotype by crossing it with a homozygous recessive organism.
