• science

• biology

• genes

• genetics

the study of how traits are passed down from generation to generation.

​

​Genetics

Multiple Choice

Which part of the cell holds the genetic material (DNA)?

• ribosomes

• nucleus

• nucleolus

• golgi body

Multiple Choice

Tightly coiled up bundles of DNA are called:

• chromosomes

• genes

• proteins

• traits

Are tightly coiled up bundles of DNA.

​

​Chromosomes

Multiple Choice

True or False: Chromosomes are made up of DNA

• False

• True

Multiple Choice

A section of DNA that codes for a particular protein:

• allele

• DNA

• chromosome

• gene

Are sections of DNA ​that code for particular proteins.

​Genes

​Genotype:

• a person's genetic makeup

• we write alleles with letters

• a genotype for a particular trait is written as 2 letters (one allele from mother and one allele from father).

• examples: Bb, EE, gg (they must be of the same letter).

Multiple Choice

Which is the correct order?
