Closely related species whose populations are sometimes allopatric showing greater morphology similarity but in a sympatric with distinct morphology due to

#Applied Microbiology
  1. Sympatric populations, which would potentially intraspecific competition for resources, show differences in body structures and in the resources they use
  2. Sympatric populations may influenced to dissimilar environmental condition, differences in body structures and in the resources they use
  3. Sympatric populations, which would potentially compete for mate choice, show differences in body structures and in the resources they use
  4. Interspecific competition in this system could change the morphology of competing species of sympatric population

Statement I: Endomitosis is a cellular process where haploid cells duplicate their chromosomes without undergoing nuclear division, resulting in the formation of diploid cells.
Statement II: In plant tissue culture, this process is primarily utilized to generate highly heterozygous plants for hybrid vigor.

#Plant Biotechnology

Assertion (A): Plants regenerated from stem segment-derived callus on auxin-cytokinin medium can be diploid and homozygous.
Reason (R): The presence of auxin and cytokinin prevents chromosome duplication during the cell cycle.

In the light of the above statements, choose the correct answer from the options given below:
