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.
Answer:
Biomes are determined by climate zones.
Explanation:
Because the makeup of a biome is dependent on its climate, biomes are often regarded as a synonymous with climate zones.
Answer:
In cases of immune system overactivity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body's ability to fight invaders, causing vulnerability to infections.
Explanation:
Answer:
B
Explanation:
Valleys are created by streams of running water
Astronomers have seen stars forming within a nebular cloud. As the nebular cloud condenses and its own gravitational attraction collapses it, heat and energy build up creating a planet.
