Document Summary
Blending inheritance: traits in the offspring resemble the average to those in parents. Hybridization: interbreeding between two different varieties or species of an organism. True breeding: that the physical appearance of the offspring in each successive generation is identical to the previous one. Reciprocal crosses: crosses in which the expressions of the trait in the female and male parents are interchanged. Allele: different forms of a gene. F2 generation: produced by allowing the f1 flowers to undergo self-fertilization. Principle of segregation: separation of alleles into different gametes. Heterozygous: the two alleles for a given gene inherited from each parent are different. Testcross: any cross of an unknown genotype with a homozygous recessive genotype incomplete dominance the phenotype of the heterozygous genotype is intermediate between those of the homozygous genotypes. Principle of independent assortment: segregation of one set of alleles of a gene pair is independent of the segregation of another set of alleles of a different gene pair.
