Most reptiles , including lizards and snakes reproduce sexually . Despite this parthenogenesis has been observed to occur natura
Natasha2012 [34]
A is your answer. When only one parent produces the offspring, they are essentially cloning themselves, and it is called asexual reproduction. The offspring only have the genes of the one parent. A lack of genetic diversity is one of the drawbacks to asexual reproduction.

Genetic diversity

Explanation:

Sexual reproductions, mutation, and crossing-over generates a wide range of genetic diversity within a population.

  • Sexual reproduction is a type of reproduction in which gametes fuses to produce a fertile and viable offspring.
  • Mutation is the process of altering genetic sequences in population to production new breeds called mutants.
  • Crossing-over is the exchange of chromosomes between two homologous pairs.

All these processes ensures that a pool of diverse gene exists within a population in order give competitive and adaptability advantage to organisms.
