Question
Chapter 19, Problem 2RQ
Summary Introduction
To state: The theory of segregation and whether segregation occurs during mitosis and meiosis.
Introduction: Law of segregation was proposed on Mendel’s work on pea plants. Mendel proposed the law of segregation based on the results of monohybrid cross that “two alleles at any locus tend to separate from each other, so they end up in different gametes”.
