BSC 1010 Study Guide - Final Guide: Mendelian Inheritance, Reciprocal Cross, Gene Expression
Document Summary
Mendelian genetics o autosomal dominant, recessive and x linked. Concepts of inheritance before mendel: prefromationist idea a small person called the homunculus lived in every sperm/egg, blending inheritance. What were the advantages of using pea plants offspring are a blend of the characterisitcs of their parents several variations are available quick generation time produce many offspring capable of self fertilization. How were pea plants fertilized (self versus cross fertilization) anthers were removed from the flower pollen from the 2nd second flower is transferred to the stigma of the flower where it was removed alternation in nucleic acid sequence. Alleles location of a gene in a chromosome. Phenotype o o o o o outward expression of the genotype. Monohybrid cross: offspring cross between one trait. Dihybrid crosses (redheads and freckles: pairs of traits to determine that the character did assort independently. Note: color blindness is a sex-linked recessive disorder. Codominance -both alleles are expresssed at the same time.
