Genetics Practice

Define Alleles

• Molecule which contains the genetic information for an organism.

• Different versions of the same gene.

• all the chromosomes/DNA that code for an individual’s traits.

• Condensed DNA that is visible during cell division.

Define Gene

• Condensed DNA that is visible during cell division.

• Different versions of the same gene.

• A section of DNA that codes for specific proteins/traits.

• Molecule which contains the genetic information for an organism.

What is the relationship between phenotype and genotype?

• The phenotype determines the genotype.

• The genotype determines the phenotype.

• There is no relationship between phenotype and genotype.
