Genetics for Kids

Genetics is the science of genes and heredity. Inside the nucleus of all your body cells are 23 pairs of chromosomes. Each chromosome carries hundreds to thousands of genes on it....(Read more...)

LS3.A Inheritance of traits

K-2 Young organisms are very much, but not exactly, like their parents and also resemble other organisms of the same kind.

3-5 Different organisms vary in how they look and function because they have different inherited information; the environment also affects the traits that an organism develops.

6-8 Genes chiefly regulate a specific protein, which affect an individual’s traits.

9-12 DNA carries instructions for forming species’ characteristics. Each cell in an organism has the same genetic content, but genes expressed by cells can differ

 

LS3.B Variation of traits

6-8 In sexual reproduction, each parent contributes half of the genes acquired by the offspring resulting in variation between parent and offspring. Genetic information can be altered because of mutations, which may result in beneficial, negative, or no change to proteins in or traits of an organism.

9-12 The variation and distribution of traits in a population depend on genetic and environmental factors. Genetic variation can result from mutations caused by environmental factors or errors in DNA replication, or from chromosomes swapping sections during meiosis.
