Chapter 1: The role of microevolutionary in macroevolutionary change.
Macroevolutionary changes are the major evolutions changes that occur over time, and it majorly shows the origin of the organism of a new kind of previously existing and genetically different ancestral types. On the other hand, macroevolutionary changes are the changes that occur in the gene pool or genome, of a specific species of an organism within a specific time as a result of alteration of successfully reproducing organisms in a population. Its role is mainly to show adaptations or variations, changes that occur within a group with descendants of the same ancestry allowing the best trait to be selected for a given set of conditions during artificial selection (Strauss et al., 2010).
Chapter 2. Traits studied by Gregor Mendel study and the importance of his research in understanding human variation
He carefully designed experiments using pea plants as he studied the traits of the flower and seed colours, pod and seed shapes, and flower positions to come up with a numerical relationship of the traits that appear in the progeny of hybrids. From his theory of evolution, he brought up basic facts of sexual reproduction and cell division that also applies to human evolution since the hereditary mechanisms are essentially similar for all complex cells of organisms.
Chapter 3. The important function accurate DNA replication information of new cells
The accurate segregation and replication of a chromosomal DNA are important for high-fidelity genetic information transmission from one generation to another.
4. The difference between phenotypes and genotypes
The genotype is the organisms' genetic makeup or the genetic information contained on two alleles within a cell while phenotype is the detectable or an observable expression of the traits of an organism (Strauss, 216). The fundamental difference between blood types is the type of antigen, antibody and Rhesus factor that the blood type contains.
