Chromosomes and Inheritance

Front

What is Mitosis?

Back

Mitosis is a type of cell division that results in two identical daughter cells, used for growth, asexual reproduction, and replacing damaged cells.

Front

What is Meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing gametes (sperm and egg cells) for sexual reproduction.

Front

What are Chromosomes?

Back

Chromosomes are long strands of DNA wrapped around proteins, containing the genetic information of an organism.

Front

How many chromosomes do humans have?

Back

Humans have 46 chromosomes in each body cell, arranged in 23 pairs.

Front

What is a Gamete?

Back

A gamete is a reproductive cell (sperm or egg) that carries half the genetic information of an organism.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.

Front

What is a Pedigree?

Back

A pedigree is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors.

Front

What is the purpose of Pedigrees?

Back

Pedigrees are used to track traits in families and make determinations about the inheritance of those traits.

Front

What is the difference between Mitosis and Meiosis?

Back

Mitosis produces two identical cells for growth and repair, while Meiosis produces four genetically diverse gametes for reproduction.

Front

What is Asexual Reproduction?

Back

Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes, resulting in offspring that are genetically identical to the parent.
