What kind of pollination increases variation within a plant species?
The right answer is "cross" or "cross pollination" or "cross-pollination"
Why is crossing-over one of the factors that makes natural selection possible?
Crossing-over increases the genetic variation within a population, which is required for natural selection to act upon.
What can cause variation within a species?
Reproduction produces variation in population gene pools. Every time organisms reproduce, be this sexually or asexually, the genome of the offspring is slightly offset compared to that of its parent(s). Additional factors in this may be mutagenic influences in the environment, such as radiation.
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.
Are pollen grains formed within the stigma?
It could be done by animal pollination , wind pollination or even self pollination.
What kind of pollination increases variation within a plant species?
The right answer is "cross" or "cross pollination" or "cross-pollination"
Where do pollination is taking place?
self -pollination occurs within the same flower or same plant
What is thetransfer of pollen within same flower?
Cross-pollination
What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
What are specific examples of variation within a species?
Human species, as in the variation in height.
What is decontinuous variation?
Variation within a population in which few or no intermediate phenotypes fall between the extremes.
What is a rhythmic variation?
rhythmic variation is shortening the lenght of some notes within a group of notes
Why is crossing-over one of the factors that makes natural selection possible?
Crossing-over increases the genetic variation within a population, which is required for natural selection to act upon.
What is a difference within a population?
A variation within the population. Height in humans is an example of this.
Which process produces the most variation within a species?
Variations occurs in species due to the process of "Crossing over"
What can cause variation within a species?
