The punnet square can be described as a diagram which shows the outcomes of a cross. A punnet square will help us know what will be the probability for a particular trait to occur in the offsprings.
Genes might have the same or different alleles. If the alleles for a gene are similar in an organism, the organism is said to be homozygous for the trait. If the alleles are different, then the organism is termed as heterozygous. 
A dominant allele is the one which which suppresses the effect of the recessive allele. A recessive allele gets masked by a dominant allele.

Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.
