MP2 9 Weeks Test Review

Front

What is the significance of genetic variation in cellular processes?

Back

Genetic variation allows for diversity in the resulting cells, which is crucial for evolution and adaptation.

Front

In which phase of meiosis does crossing over occur?

Back

Crossing over occurs in prophase 1 of meiosis.

Front

What theory describes periods of slow evolutionary change interrupted by rapid changes?

Back

The theory of punctuated equilibrium describes this pattern.

Front

What common characteristic do squirrels and lions share?

Back

Both squirrels and lions are mammals.

Front

What is the primary cause of genetic variation during meiosis?

Back

The primary cause of genetic variation during meiosis is the crossing over of chromosomes.

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 role of chromosomes during meiosis?

Back

Chromosomes carry genetic information and are involved in the segregation and recombination of genes during meiosis.

Front

Explain the process of crossing over.

Back

Crossing over is the exchange of genetic material between homologous chromosomes during prophase 1 of meiosis, leading to genetic diversity.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.
