What is DNA?
is a self-replicating strand of molecules that are present in nearly all living things.
A piece, section or sequence of DNA that is passed on from parent to offspring that determines a certain
A form of reproduction that does not include the fusion / uniting of two sex cells. The offspring of this type of reproduction is an exact copy of the parent.
Differences in the DNA / Genes between individuals within a population.
What are Chromosomes?
A piece, section or sequence of DNA that is passed on from parent to offspring that determines a certain
Thread like structures made up of DNA, found in the nucleus of living things and contain information called genes.
(deoxyribonucleic acid) is a self-replicating strand of molecules that are present in nearly all living things.
A distinguishing quality or characteristic belonging to an organism. Like color, shape and more.

What is a Trait?
Differences in the DNA / Genes between individuals within a population.
The most common type of reproduction involving the fusion of two sex cells, each from a different parent. The offspring results in a combination of different traits from each parent.
A form of reproduction that does not include the fusion / uniting of two sex cells. The offspring of this type of reproduction is an exact copy of the parent.
A distinguishing quality or characteristic belonging to an organism. Like color, shape and more.
Asexual Reproduction
A form of reproduction that does not include the fusion / uniting of two sex cells. The offspring of this type of reproduction is an exact copy of the parent.

Sexual Reproduction
The most common type of reproduction involving the fusion of two sex cells, each from a different parent. The offspring results in a combination of different traits from each parent.
