Genetics Review

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are the stages of mitosis?

Back

The stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during Prophase?

Back

During Prophase, the nuclear membrane disappears, chromosomes condense and become visible, and the spindle apparatus begins to form.

Front

What happens during Metaphase?

Back

During Metaphase, chromosomes line up in the center of the cell, and spindle fibers attach to the centromeres of the chromosomes.

Front

What happens during Anaphase?

Back

During Anaphase, sister chromatids are pulled apart and move toward opposite poles of the cell.

Front

What happens during Telophase?

Back

During Telophase, the nuclear membrane reforms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, representing the alleles inherited from the parents.

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.
