The sexual life cycle increases the genetic variation in a species by allowing independent assortment of chromosomes, random fertilization, and crossing over to occur.

∙ 13y agoWhen each new life form is born, it is born with a slight variation; bigger, faster, smarter, etc., which allows the stronger to adapt to more situations with the variations in them which, in turn, will create evolution and an entirely different branch in the species.
The male has to be well adapted to its environment to reach reproduction as does the female. This way the offspring has the chance of inheriting the beneficial variations of both parents. This is probably why most species occur as 2 sexes.

What is a major cause of variation within species?
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
An advantage of sexual reproduction is?
An advantage of a sexual reproduction is that it is able to produce more offspring because of the mate. Children are different from the parents and more genetic variation species.
Does sexual reproduction cause a narrow range or variation or a wide range of variation in species?
SIM=
Sexual reproduction evolved before the evolution of?
Multicellular organisms
Why is sexual reproduction preferable to a species?
It promotes genetic variation.
Which process is a cause of variation in a species?
Sexual Reproduction Genetic mutation
Why does sexual reproduction result in genetic variation in a species?
It mixes the chromosomes of the two parents
Why does sexual reproduction the genetic variation in a species?
A fertilized egg has a mixture of alleles from the two parents.
Why does sexual reproduction result in more in genetic variation in a species?
It mixes the chromosomes of the two parents
Why does sexual production result in more genetic variation in a species?
It mixes the chromosomes of the two parents
Why does sexual reproduction increase the variation in a species?
A fertilized egg has a mixture of alleles from the two parents.
What results in the most diverse offspring?
Sexual reproduction leads to variety in offspring.
A change in the genetic material that produces variation in a species may be the result of?
immigration, mutation and sexual reproduction.
What advantages does sexual reproduction provide for sponges?
Sexual reproduction means there is much greater scope for genetic variation of offspring. Variation is good for any species as it is this variation that allows for adaption e.g. the variation might provide some individuals with resistance to a new disease that affects the species, hence those individuals survive and thrive.
