What is an observable heritable feature that may vary among individuals?

What is one of two or more detectable variants in a genetic character?

What term refers to organisms that produce offspring of the same variety over many generations of self-pollination?

What is the mating or crossing of two true-breeding varieties called?

What are the true-breeding parent individuals from which F1 hybrid offspring are derived in studies of inheritance?

What is the first filial, hybrid offspring arising from a P generation cross called?

What are the offspring resulting from interbreeding of the hybrid F1 generation called?

What are any of the alternative versions of a gene that may produce distinguishable phenotypic effects?

What is an allele that is fully expressed in the phenotype of a heterozygote called?

What is an allele whose phenotypic effect is not observed in a heterozygote called?

What is Mendel's first law, stating that the two alleles in a pair segregate into different gametes during gamete formation?

What is a diagram used in the study of inheritance to show the predicted genotypic results of random fertilization of genetic crosses between individuals of a known genotype?

What term describes having two identical alleles for a given gene?

What term describes having two different alleles for a given gene?

What are the observable physical and physiological traits of an organism, which are determined by its genetic makeup?

What is the genetic makeup or set of alleles for an organism called?

What is an organism that is heterozygous with respect to a single gene of interest called?

What is the process of breeding an organism of unknown genotype with a homozygous recessive individual to determine the unknown genotype?

What is an organism that is heterozygous with respect to two genes of interest called?

What is Mendel's second law, stating that each pair of alleles segregates, or assorts, independently of each other pair during gamete formation?

What is the situation in which the phenotype of the heterozygote and dominant homozygote are indistinguishable?

What is the situation in which the phenotype of heterozygotes is intermediate between the phenotypes of individuals homozygous for either allele?

What is the situation in which the phenotypes of both alleles are exhibited in the heterozygote because both alleles affect the phenotype in separate, distinguishable ways?
