Summary Introduction

To determine: The adaptive advantages provided by asexual reproduction.

Introduction: Asexual reproduction is a uni-parental process (only one parent plant is involved). In this type of reproduction, offspring will only have the characteristics and traits from a single parent.

Explanation of Solution

The adaptive advantages provided by asexual reproduction are as follows:

  • Production of a large number of offspring over a short period of time.
  • Perpetuation of successful genotypes in stable habitats.
  • It does not mate and is friendly to the environment.

Summary Introduction

To determine: The adaptive advantages provided by sexual reproduction.

Introduction: Sexual reproduction is the process that involves the formation of diploid zygote by the fusion of male and female gamete. The resulting zygote has genetic makeup that is different from its parents and this change in genetic makeup is known as genetic variation.

Explanation of Solution

The adaptive advantages provided by sexual reproduction are as follows:

  • Greater level genetic diversity enhances the reproductive success.
  • It promotes survival.
  • It removes harmful alleles from the population.

c.

Expert Solution

Summary Introduction

To determine: Whether the self-fertilization of hermaphrodite is sexual or asexual reproduction.

Introduction: Reproduction is the process by which the organisms propagate their species by the union of the male and females gametes in the case of sexual reproduction or by other asexual means. Sexual reproduction and asexual reproduction are the two types of reproduction.

Explanation of Solution

Self-fertilization of hermaphrodite is a sexual reproduction. This is because involves the union of male and female gametes. There will be genetic variation within offspring as a result of genetic recombination during meiosis and fertilization.
