Each organism has two alleles for each gene, which separate during gamete formation so each gamete carries only one allele.
Alleles of different genes assort independently during gamete formation, leading to genetic variation.
A form of inheritance where the heterozygote shows an intermediate phenotype between the two homozygotes.
Both alleles in a heterozygote are fully expressed, such as in ABO blood groups.
One gene influences multiple, seemingly unrelated phenotypic traits.
Multiple genes contribute to a single phenotypic trait, often resulting in continuous variation.
Inheritance of traits through mechanisms that affect gene expression without changing the DNA sequence, often influenced by environmental factors.
Genes are located on chromosomes, which segregate and assort independently during meiosis, explaining patterns of inheritance.
Genes located close together on the same chromosome that tend to be inherited together.
Traits associated with genes located on sex chromosomes, often showing different patterns in males and females.
A cross between an organism with an unknown genotype and a homozygous recessive organism to determine the unknown genotype.
A diagram used to predict the genotypes and phenotypes of offspring from a genetic cross.
A chart that shows the inheritance pattern of a trait through several generations in a family.
Different versions of a gene that may produce variations in a trait.
An allele that expresses its phenotype even when heterozygous with a recessive allele.
An allele whose phenotype is masked in the presence of a dominant allele.
Having two identical alleles for a particular gene.
Having two different alleles for a particular gene.
The genetic makeup of an organism, referring to its specific alleles.
The observable physical or biochemical characteristics of an organism, determined by genotype and environment.
Individuals who are heterozygous for a recessive disorder and do not show symptoms but can pass the allele to offspring.
Used to calculate the probability of two independent events both occurring by multiplying their individual probabilities.
A genetic cross between individuals differing in one trait to study inheritance patterns.
A genetic cross between individuals differing in two traits to study independent assortment.
The specific physical location of a gene on a chromosome.
A human blood group system demonstrating codominance with alleles A, B, and O.
The most common phenotype or genotype found in natural populations.
The mating or breeding of two organisms to study inheritance of traits.
Offspring resulting from a cross between parents with different traits or genotypes.
