Ch 12 Mendelian Genetics and Beyond w/ Meiosis

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses, such as 'Bb' or 'RR'.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis is the process of cell division that results in two identical daughter cells, while meiosis is the process that produces gametes (sex cells) with half the number of chromosomes.

Front

What are gametes?

Back

Gametes are sex cells (sperm and egg) that carry half the genetic information of an organism.

Front

What are somatic cells?

Back

Somatic cells are all body cells except for gametes; they contain the full set of chromosomes.

Front

If a person has a genotype of RR, what alleles do their gametes carry?

Back

All gametes will carry the R allele.

Front

What blood type can a person with O+ receive?

Back

A person with O+ can receive O- blood.

Front

What is the purpose of meiosis?

Back

The purpose of meiosis is to produce gametes for sexual reproduction, ensuring genetic diversity.

Front

Define homozygous. Give an example.

Back

Homozygous refers to having two identical alleles for a particular gene, such as 'AA' or 'aa'.

Front

Define heterozygous. Give an example.

Back

Heterozygous refers to having two different alleles for a particular gene, such as 'Aa'.

Front

What is a phenotype?

Back

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