Genetics and Blood Type Concepts

Front

What is a genotype?

Back

A genotype is the genetic makeup of an individual, represented by the alleles inherited from their parents.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype consists of two different alleles for a particular gene, such as Bb.

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 a Punnett Square help you determine?

Back

It helps determine the ratio of phenotypes, the ratio of genotypes, and predict possible traits of offspring.

Front

What determines an individual's blood type?

Back

An individual's blood type is determined by genetics.

Front

What are alleles?

Back

Alleles are different variations of the same gene that can produce different traits.

Front

What is a phenotype?

Back

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

Front

What is the probability represented by each box in a Punnett Square?

Back

Each box in a Punnett Square represents a 25% probability of an offspring's genotype.

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 is the significance of the ABO blood group system?

Back

The ABO blood group system classifies human blood into four main types (A, B, AB, O) based on the presence or absence of antigens.
