week 3.4 Review

Front

What is heredity?

Back

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

Front

What does homozygous dominant mean?

Back

Homozygous dominant refers to having two identical dominant alleles for a trait, represented as 'AA'.

Front

What is the genotype for a homozygous recessive organism?

Back

The genotype for a homozygous recessive organism is represented as 'aa'.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, consisting of the alleles inherited from its parents.

Front

What is a phenotype?

Back

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

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, represented as 'Aa'.

Front

What is an allele?

Back

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

Front

What is the significance of a Punnett square?

Back

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

Front

What does it mean if an organism is homozygous?

Back

An organism is homozygous if it has two identical alleles for a specific trait.

Front

What is the expected phenotype ratio in a monohybrid cross?

Back

The expected phenotype ratio in a monohybrid cross is typically 3:1 for dominant to recessive traits.
