Genetics and Chromosomes

What is a phenotype?

• a gene pair where each allele in the pair is the same version

• a gene pair where each allele in the pair is a different version

• the physical expression of a set of genes for a particular trait

What is a chromosome?

• a gene pair where each allele in the pair is the same version

• long strand of DNA condensed (or supercoiled) into a stick-like structure

• a gene pair where each allele in the pair is a different version

What are alleles?

• a gene pair where each allele in the pair is the same version

• a gene pair where each allele in the pair is a different version

• Since human cells carry 2 copies of each chromosome (one from each parent), they have 2 versions of each gene

What is DNA?

• molecule that carries the genetic information in your body's cell; it is made up of four chemicals called bases that are abbreviated A,T,C, and G.

• the set of genes responsible for a particular trait or phenotype

• a distinct portion of your cell's DNA that carries genetic instructions for a particular protein

What is Homozygous?

• organelle that contains a eukaryotic cell's genetic material

• a gene pair where each allele in the pair is the different version

• a gene pair where each allele in the pair is the same version

What is the nucleus?

• the set of genes responsible for a particular trait or phenotype

• organelle that contains a eukaryotic cell's genetic material

• a distinct portion of your cell's DNA that carries genetic instructions for a particular protein

What is genotype?

• the physical expression of a set of genes for a particular trait

• a distinct portion of your cell's DNA that carries genetic instructions for a particular protein

• the set of genes responsible for a particular trait or phenotype

What are base pairs?

• molecules that will bond together, such as adenine with thymine and cytosine with guanine

• a gene pair where each allele in the pair is a different version

• a distinct portion of your cell's DNA that carries genetic instructions for a particular protein

What does heterozygous mean?

• a gene pair where each allele in the pair is a different version

• a gene pair where each allele in the pair is the same version

• a set of genes responsible for a particular trait or phenotype

What is a genome?

• a distinct portion of your cell's DNA that carries genetic instructions for a particular protein

• a gene pair where each allele in the pair is a different version

• organism's complete set of genetic material (DNA) that contains all the information needed to build and maintain that organism
