Relating to two alleles of a gene pair in a heterozygote that are both fully expressed. When alleles for both white and read are present in a carnation, for example, the result is a rad and white carnation
a) homozygous
b) incomplete dominance
c) sex linked
d) codominant

The smallest pieces of chromosomes; determine what we look like
a) pedigree
b) genes
c) heredity
d) genetics

The actual code that alleles or genes posses (eg. TT, Tt, or tt). The gene may or may not be expressed when you observe a living organism
a) codominant
b) genotype
c) Allele
d) carrier

Diagrams that are used to trace the inheritance of a specific trait, abnormality, or disease. Standard symbols are used to represent males, females, mating and offspring
a) pedigree
b) carrier
c) dominant
d) incomplete dominance

In humans and other mammals a sex chromosome that is normally present only in male cells.
a) x chromosome
b) carrier
c) Y chromosome
d) alleles

Person or other organism that has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease
a) carrier
b) genotype
c) phenotype
d) incomplete dominance

The study of heredity and the variation of inherited characteristics
a) carrier
b) alleles
c) genetics
d) genes

A genotype consisting of two identical alleles of a gene for a particular trait
a) homozygous
b) phenotype
c) genes
d) heterozygous

Transmission of genetic traits from parent to offspring
a) codominant
b) genetics
c) heredity
d) pedigree

The trait (allele) of an organism that can be masked by the other form of that trait (allele)
a) recessive
b) dominant
c) y chromosome
d) incomplete dominance

Condition in which a trait in an individual is intermediate between the phenotype of its two parents (blended)
a) incomplete dominance
b) codominance
c) genotype
d) carrier

An alternate form of a gene for one trait.
a) heredity
b) sex linked
c) dominant
d) allele

A genotype consisting of two different alleles of a gene for a particular trait. Also referred to as a hybrid
a) codominant
b) homozygous
c) heterozygous
d) recessive

The observable or detectable characteristics of an individual organism--the observable expression of a genotype
a) phenotype
b) genotype
c) heredity
d) y chromosome

In humans and other mammals a sex chromosome, two of which are normally present in female cells and only one in male cells
a) genotype
b) x chromosome
c) heterozygous
d) homozygous

a gene or heritable characteristic carried by a sex chromosome
a) codominant
b) sex linked
c) alleles
d) incomplete dominance

Observed trait of an organism that masks the recessive allele of a trait
a) pedigree
