Answer: Option A ,Band C.
Explanation:
Sympatric speciation is the evolution or isolation of new species from the original populations of species occupying in the same geographical area.

Answer:
B) If two non functional copies are inherited, the pea will be wrinkeld.
Explanation:
The gene for starch debranching is one of the genes that regulate more than one genetic trait. The starch debranching gene also regulates the seed shape in peas. The gene has two alleles. The allele B is completely dominant over allele "b" with respect to seed shape. Both homozygous and heterozygous dominant genotypes (BB and Bb) produce smooth seeds while homozygous recessive genotype (bb) imparts wrinkled shape to the seeds.
