Pattern of inheritance involving single genes with dominant and recessive alleles that follow Mendel’s laws?

Rule stating that in a heterozygote the dominant allele masks the recessive allele?

Allele that is expressed phenotypically even when only one copy is present?

Allele that is expressed only when two copies are present?

Study of how traits are passed from parents to offspring through genes described by Gregor Mendel?

Segment of DNA that controls a specific trait?

Alternative form of a gene found at the same locus?

Specific physical location of a gene on a chromosome?

Law stating that allele pairs separate during gamete formation so each gamete carries one allele?

Sex cell that carries only one allele for each gene?

Individual who carries one recessive allele but does not show the disease?

Disorder in which one copy of a mutant gene on an autosome is enough to cause disease?

Disorder that appears only when two recessive alleles are inherited?

Non-sex chromosome in humans?

Law stating that alleles of different genes separate independently during gamete formation?

Genes located close together on the same chromosome and tend to be inherited together?

Diagram used to predict possible genotypes and phenotypes of offspring?

Genetic cross involving one trait only?

Ratio showing the proportion of different genotypes in offspring?

Ratio showing the proportion of observable traits in offspring?

Genetic cross involving two traits at the same time?

Inheritance patterns that do not follow Mendel’s laws?

Pattern of inheritance where the heterozygote shows an intermediate phenotype?

Pattern of inheritance where both alleles are fully and equally expressed?

Inheritance of traits controlled by genes on sex chromosomes?

Inheritance of traits carried specifically on the X chromosome?

Condition of having only one copy of a gene, common in males for X-linked traits?

Female who carries an X-linked recessive allele without showing symptoms?
