Microevolution: The change in the genetic makeup of a population from generation to generation Mendel’s model: the particulate hypothesis of inheritance Quantitative characteristics: characteristics of a population that vary along continuum. Eg. Fur length in mammals Population genetics: study of how populations change genetically over time. Modern synthesis: a comprehensive theory of evolution that integrated…
Blending theory of inheritance: hereditary trait blend evenly in offspring through mixing of parent’s blood. Mendel studied heritable characteristics called characters; plant color and seed shape. Variation in character= Trait Monohybrid cross between to heterozygous parents (Dr x Dr) F1 generation will yield phenotypic ration of 3:1 (1/4 getting PP or pp, or ½ getting…
Incomplete Dominance – there is an interaction between 2 alleles in the homozygous form – alleles are semi – or incompletely dominant and act together to yield an intermediate heterozygote – usually phenotypically between the two homozygote Codominance – when definite product or substance controlled by each allele is identified ex. of incomplete dominance: Andalusian…
