- Genetics are..
- the branch of biology that studies heredity.
- What are genetic disorders?
- THe harmful effects that are produced by mutated genes.
- What is Heredity?
- The transmission of traits from parent to offspring.
- What is self-pollination?
- when the flower does not open fully and fertilizes itself.
- Cross-pollination is...
- the transferring the pollen from the flower of one plant to the flower of a different plant.
- True-breeding is...
- when all the offspring would display only one form of a particular trait.
- What is P generation?
- Plants taht displayed only one form of a particular trait.
- F1 generation is...
- offspring from a cross of two varieties.
- What is an f2 generation?
- offspring from crosses among individuals of the F1 generation.
- What is a dominant trait?
- a trait that is expressed when it's allele is homozygous or heterozygous.
- A recessive trait is..
- a trait taht was not exspressed in the F1 generation.
- Homozygous refers to..
- a pair of genes with two identical alleles for a trait.
- What is an allele?
- an alternative form of a gene
- A heterozygous refers to...
- a pair of genes with two different alleles for a trait.
- What is a phenotype?
- An observable characteristic of an organism.
- A genotype is...
- a genetic constitution of an organism as indicated by its set of alleles.
- The law of segregation states...
- that the members of each pair of alleles separate when the gametes are formed
- The law of independent assortment state that...
- pairs of alleles separate independently of one another during gamete formation.
- What is Probability?
- Probability is the likelihood that a specific event will occur.
- What is the formula for Probability?
- PRbability = Number of one kind of possible outcome divided by the total number of all possible outcomes.

- a cross that provides data about a pair of contrasting traits.
- A Punnet square is..
- A diagram used by biologists to predict the possible outcome of a cross.
- A dihybrid cross is..
- a cross that involves two pairs of contratsting traits.
- What is incomplete dominance?
- a trait that is intermediate betweent the two parents, a phenomenon.
- A codominance is...
- the two dominant alleles are expressed at the same time.
- Multiple alleles are...
- genes with more than two alleles.
- What is continuous variation?
- a trait that's controlled by several genes and exhibits a variety of phenotypes a genetic phenomenon.
- A sickle cell anemia is..
- an example of a recessive genetic disorder.
