What is a Gene?

• Characteristic of having two of the same alleles at the same locus of sister chromatids

• Specific region of DNA that codes for a particular protein.

• Allele that is expressed when two different alleles are present in an organism’s genotype.

• Collection of all of an organism’s genetic information that codes for traits

What is a Alleles?

• Specific region of DNA that codes for a particular protein.

• Any of the alternative forms of a gene that occurs at a specific place on a chromosome.

• Allele that is expressed when two different alleles are present in an organism’s genotype.

• Collection of all of an organism’s physical characteristics.

What is a Homozygous?

• Characteristic of having two difference alleles that appear at the same locus of sister chromatids

• Characteristic of having two of the same alleles at the same locus of sister chromatids

• Genotype

• Collection of all of an organism’s genetic information that codes for traits

What is a Heterozygous?

• Any of the alternative forms of a gene that occurs at a specific place on a chromosome.

• Allele that is expressed when two different alleles are present in an organism’s genotype.

• Specific region of DNA that codes for a particular protein.

• Characteristic of having two difference alleles that appear at the same locus of sister chromatids

What is a Dominant allele?

• Allele that is expressed when two different alleles are present in an organism’s genotype.

• Allele that is not expressed unless two copies are present in an organism’s genotype.

• Collection of all of an organism’s physical characteristics.

• Model for predicting all possible genotypes resulting from a cross, or mating.

What is a Recessive allele?

• Any of the alternative forms of a gene that occurs at a specific place on a chromosome.
