The following section of the paper reflects a comparative analysis of different
biological behaviours thoroughly.
Difference between Mitosis and Meiosis
Mitosis is defined as a process of asexual reproduction. In this process, the cell gets
divided into two producing a replica and each resulting diploid cell consists of equal number
of chromosomes. On the other hand, meiosis is a cellular reproduction process. In this
process, number of chromosomes is reduced by half through the separation of homologous
chromosomes. As a result it produces two haploid cells. For example, mitosis replicates the
somatic cells of the body and whereas, gametes are produced in meiosis (Ohkura, 2015).
Difference between Phenotype and Genotype
The phenotype is basically the physical appearance of an organism and on the other
hand, genotype is the genetic composition of an organism. Phenotypes are always observable
as we can notice one’s eye colour, hair colour, weight, height, skin colour and others. But, the
genes, responsible for such characters present in the DNA cells can never be noticed.
Therefore, example of the phenotype is eye colour but the gene behind such character is the
example of the genotype (Adilardi, Ojanguren-Affilastro & Mola, 2016).
Difference between Homozygous and Heterozygous
Homozygous is a trait when diploid organisms carry two copies of gene that are
identical alleles and it brings similar individuals. It is pure for a trait produces only one type
of gametes. Again, if the diploid organisms carry two copies of gene which are different
alleles are called heterozygous (Adilardi, Ojanguren-Affilastro & Mola, 2016). It brings
dissimilar individuals and rarely pure. Also, it produces two different types of gametes.
