Balancing selection is a type of natural selection that balances two or more alleles in population allows maintaining genetic diversity. Which of the following allowed to this type of selection?
A- Heterozygote has the highest level of Fitness than normal homozygote
B- If rare phenotypes are favored over common phenotypes
C- Introduction of new allele in to a population by mutation and allowed to higher fitness in individuals
D- One homozygote has a highest level of fitness than heterozygote and another homozygote

A graph shows the frequency distribution of the character (body size). B graph shows the relation between body size and fitness, within one generation, and the third the expected change in the average for the character over many generations (if body size is inherited). Which of the following correct figure for Average size with respect to time?

Phylogenies can be used to test whether speciation has been sympatric or allopatric. Following figure shown a new species arises by allopatric speciation, its nearest relative will usually live in a different geographic area, such as in a nearby lake. Which of the following phylogenetic tree is correct?
