Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Pun
castortr0y [4]

Answer:

True

Explanation:

There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of  Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing  random distribution of the two traits. This random distribution cannot be captured through punnet square.  

The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.

Explain the peppered moth events in terms of natural selection
LenKa [72]

Answer:

Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed. All living things respond to natural selection.

madam [21]
Aerobic cellular respiration, glucose is metabolised in the presence of oxygen and leads to the formation of energy as a main product. the by products are carbon dioxide and water. The process takes place in four phases: glycolysis, pyruvate oxidation, citric acid cycle, and oxidative phosphorylation.
