Genetics Test

Front

What is a pedigree chart used for?

Back

A pedigree chart is used to track inheritance patterns in families.

Front

What process in the first phase of meiosis increases genetic diversity?

Back

Crossing Over allows the increase of genetic diversity to begin.

Front

What can chromosomal mutations result from?

Back

Chromosomal mutations can result from nondisjunction during meiosis, environmental factors, and gene mutations.

Front

What is nondisjunction?

Back

Nondisjunction is the failure of chromosomes to separate properly during cell division.

Front

In a Punnett square, what do the letters along the top and side represent?

Back

The letters along the top and side represent the genotypes of the parents.

Front

Define meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is the significance of crossing over in meiosis?

Back

Crossing over increases genetic variation by exchanging genetic material between homologous chromosomes.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

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 role of a Punnett square?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from a genetic cross.
