Document Summary
Uniparental inheritance one parent contributes more to an offspring"s trait. Aristotle hypothesis: sperm was a fully formed male. Blended inheritance parental traits are blended into offspring. For many problems there is a model on which it can easily be most conveniently studied . Could obtain and maintain pure-breeding lines bred true producing same trait generation upon generation. Cross-fertilize to create hybrids b/w pure breeding lines. Dominant allele that manifests itself regardless of another allele present. Recessive allele whose affect is masked when dominant allele is present. Homozygous both alleles at given diploid locus is the same. Heterozygous one dominant and recessive allele ate diploid locus. Homozygote individual that is homozygous at locus in question. Heterozygote individual that is heterozygous at locus in question. True breeding homozygous at locus in question. Self inbreeding cross involves individuals that are genetically identical. Antagonistic pairs clear cut traits, one or the other. Dominance one trait is manifest in f1 hybrid.
