I think d all of the above
Answer:
b. Sympatric autopolyploidy
Explanation:
Sympatric speciation will occurs when a new species when two groups from the same ancestral population evolve without any geographical separation.
Autopolyploidy will appear when an individual possess more that two sets of chromosomes both from the same parental species
Therefore, since a new species was formed as a result of autopolyploidy. The type of speciation that occurred was Sympatric speciation.
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period.[1][2]
In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[3]
I believe that the probability of having an individual with attached earlobes will be 50%. Since the attached earlobes is recessive then its genotype will be (ee), for the unattached ear lobes the genotype will be EE, Ee. Therefore, mating between an individual with attached ear lobes (ee) and one with unattached ear lobes, heterozygous, Ee, the offspring will be; Ee, Ee, ee, or ee. Therefore; half of the offspring will have unattached ear lones (heterozygous) while another half will have attached ear lobes.
