Mendel’s Monohybrid Cross Experiment

Science > Biology > Genetic Basis of Inheritance > Mendel’s Monohybrid Cross Experiment In this article, we shall study Mendel’s monohybrid cross experiment and its conclusions. The first scientific explanation of inheritance was given by Mendel in 1866. He performed a series of experiments on garden pea in a scientific manner and proposed rules. which are […]

Three Domains of Life

Science > Biology > General Biology > Diversity of Living Organisms > Three Domains of Life Prior to 1969 organisms were classified into two kingdoms: the Plant Kingdom and the Animal Kingdom and on the basis of a cell, organisms were classified into two categories Prokaryotae or Monera (which comprised bacteria) and Eukaryotae (which comprised animals, plants, fungi, […]
