What are the reasons for Mendel’s successes in his breeding experiment?
Advertisements
उत्तर
Mendel was successful because:
- He applied mathematics and statistical methods to biology and laws of probability to his breeding experiments.
- He followed scientific methods and kept accurate and detailed records that include quantitative data of the outcome of his crosses.
- His experiments were carefully planned and he used large samples.
- The pairs of contrasting characters which were controlled by a factor (genes) were present on separate chromosomes.
- The parents selected by Mendel were pure breed lines and the purity was tested by self-crossing the progeny for many generations.
