Document Summary
Mode of inheritance: patterns in which genetic rates /conditions of certain families. Autosomal dominant: non sex chromosomes- affects every sex, will have it in every generation. Autosomal recessive: affects both sexes and skips generations through carriers heterozygous carry allele for recessive- display normal phenotype: huntington disease, sickle cell anemia. How transmission of traits occur- from parents to offspring. Heredity: transmission of traits from parents to offspring. Trait: any characteristic of an individual (physical: widows peak, straight hair line, freckles(dominant), tongue rolling, dimples (dominant) Blending inheritance hypothesis: parental traits blend such that their offspring have intermediate traits. Inheritance of acquired characteristics- parental traits are modified and then passed on to their offspring. Particulate inheritance: law of heredity: parents pass inheritable factors (genes) that retain their separate identities in offspring: genes retain separate identity between offspring from one generation to the next. Common garden pea: short reproductive cycle, not complex, easy to grow.
