PPT-SGN18 The Chromosomal Basis of Inheritance

  Studying genetics can be accomplished in part by investigating the history of discoveries that have lead to our understanding of DNA and its role in gene expression and biological inheritance. Abnormalities in Chromosomal Number. Abnormalities in Chromosomal Structure:. Rearrangements. Fragile Sites. Define:. nondisjunction. polyploidy. aneupoidy. trisomy. monosomy. Abnormalities in chromosomal number. Hypothesis: The antenna shape follows monohybrid inheritance, where the allele of Knobbed antenna is dominant and the allele for Short antenna is recessive. .
