having two different alleles for a given trait

the expression of a genotype in the appearance or function of an organism; an observed trait

the principle stating that the inheritance of alleles residing on one pair of chromosomes does not affect the inheritance of alleles on a different pair of chromosomes

pattern of gene expression in which the phenotype of a heterozygous individual is intermediate between those of the parents

the condition in which both alleles in a heterozygous organism are expressed

the existence of several alleles of a gene

a trait whose gene is carried on the X chromosome (the female sex chromosome, as compared to the male Y chromosome)

failure of a pair of homologous chromosomes or chromatid pairs to separate during meiosis or mitosis

a display of the image of a set of chromosomes sorted by number

the chance that an event will occur; the number of times an event is expected to occur divided by the total number of opportunities for the event to occur

referring to an allele that masks the presence of another allele of the same gene in a heterozygous organism

a trait whose expression is masked in a heterozygous organism

the principle stating that homologous chromosomes, with the genes they carry, separate into different gametes during meiosis such that the two alleles for a given trait each appear in a different gamete

the genetic makeup of an organism

having two identical alleles for a given trait

referring to control of the expression of a trait by several genes and environmental factors (eye color, height)
