Unit 8 Vocabulary: Heredity

Meiosis

• A chart that shows all the possible combinations of alleles that can result from a genetic cross (Sexual Reproduction)

• a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell; gametes

• An organism's genetic makeup, or allele combinations. (What you inherit)

Homozygous

• An organism that has two different alleles for a trait (Hetero=Different)

• Describes a trait that covers over, or dominates, another form of that trait.

• An organism that has two identical alleles for a trait (Homo=Same/ Purebred)

Heterozygous

• Describes a trait that covers over, or dominates, another form of that trait.

• An organism that has two identical alleles for a trait (Homo=Same/ Purebred)

• An organism that has two different alleles for a trait (Hetero=Different)

Dominant

• An allele that is masked when a dominant allele is present

• Describes a trait that covers over, or dominates, another form of that trait.

• likelihood that a particular event will occur

Recessive

• Describes a trait that covers over, or dominates, another form of that trait.

• An allele that is masked when a dominant allele is present

• likelihood that a particular event will occur

Probability

• likelihood that a particular event will occur

• A characteristic that an organism can pass on to its offspring through its genes.

• A comparison of the quantities of an outcome. Such as 3 to 1 likelihood of having a child with brown eyes.
