Heredity & Genetics - Intro Game

Front

What is heredity?

Back

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

Front

What are genes?

Back

Genes are segments of DNA that contain the instructions for the development and functioning of living organisms.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable physical traits of an organism.

Front

What is a dominant trait?

Back

A dominant trait is a genetic trait that is expressed in the phenotype even when only one copy of the allele is present.

Front

What is a recessive trait?

Back

A recessive trait is a genetic trait that is only expressed in the phenotype when two copies of the allele are present.

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 the purpose of a test cross?

Back

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

Front

What is the law of segregation?

Back

The law of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is the law of independent assortment?

Back

The law of independent assortment states that the alleles for different traits are distributed to gametes independently of one another.

Front

What is a pedigree chart?

Back

A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism in several generations.
