Heredity, Traits, and Probability

An allele that is expressed only when there are two present is called 

• a testcross.
• the law of independent assortment.
• a monohybrid cross.
• recessive.

The study of biological inheritance patterns and variation in organisms is

• generous.
• generic.
• general ed.
• genetics.

The law of segregation has two main parts:
Organism inherit 2 copies of each gene, one from each parent, AND

• the law of the land.
• the law of the jungle.
• the law of probability?
• Only one copy of a gene goes into an organism's gametes.

Monohybrid crosses are crosses that examine

• the inheritance of multiple traits.
• only two traits.
• no traits.
• only one specific trait.

The likelihood, or chance, that a particular event will happen is

• probability.
• untrue.
• independent.
• true.

Dihybrid crosses are crosses that

• examine the inheritance of two different traits.
• examine a specific trait.
• examine several hundred traits.
• examine nothing.

When two alleles of a gene are the same, they are 

• heterozygous.
• gametogenesis.
• homozygous.
• polar bodies.

When two alleles of a gene are the different, they are 

• heterozygous
• purebred.
• homozygous.
• traits.
