Basic Genetics Quiz

The study of law of chance is

• genetics

• heredity

• probability

• hybrid

The actual genes that an individual has

• genotype

• phenotype

• trait

• dihybrid

• polygenic inheritance

Different forms of the same gene, one is dominant and the other is recessive.

• alleles

• phenotype

• polygenic

• homozygous

The grid system used to determine probability in genetics problems.

• test cross

• monohybrid

• punnett square

• filial generation

A cross that involves one gene, or pair of alleles.

• test cross

• monohybrid cross

• dihybrid cross

• polygenic inheritance

A condition in which the two alleles of a gene are alike in an individual.

• homozygous

• heterozygous

• genotype

• hybrid

• sex-linked

When there are three or more alleles for the same gene.

• polygenic inheritance

• homozygous

• heterozygous

• multiple alleles

An individual that has two different alleles for a gene.

• homozygous

• heterozygous

• genotype

• phenotype

• dihybrid

The outward appearance of an individual as an expression of the gene.

• genotype

• phenotype

• trait

• dominant

• recessive

The allele that is expressed in the heterozygous condition, prevents the expression of another.

• gentoype

• phenotype

• trait

• dominant

• recessive
