Is a sexual reproduction which happen only in eukaryote?
meiosis
What must be true for natura selection to happen?
For natural selection to occur, there must be variation in traits within a population, as these variations can affect an organism's ability to survive and reproduce. Additionally, the traits must be heritable, meaning they can be passed down to the next generation. There must also be differential survival and reproduction, where individuals with advantageous traits are more likely to survive and reproduce than those without. Lastly, the environment must exert pressure that favors certain traits over others.
When does genetic variation occur?
Genetic variation occurs during the processes of meiosis and sexual reproduction when genetic material is shuffled and recombined, leading to unique combinations of genes in offspring. Mutations and genetic recombination also contribute to genetic variation by introducing new alleles and gene combinations into populations.
Why is there great variations in the offspring produced through sexual reproduction but little or no variations in the offspring produced through asexual reproduction?
In asexual reproduction there is no independent orientation of chromosomes, not crossing over and no random fertilization. Cloning the exact genetic material from organism to progeny is all asexual reproduction is. So, very little chance of anything but mutation, copying errors, are going to happen in asexual reproduction.
What does the reshuffling of chromosomes in sexual reproduction increase?
The reshuffling of chromosomes in sexual reproduction increases genetic diversity in offspring. This variation allows for different combinations of traits, providing a wider range of adaptations to changing environments and increasing the chances of survival for a species.
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
What must happen in order for evolution to exist?
Without heredity what use would there be to selection and why evolution? Just take beneficial mutations in the germ line for example. No heredity and nothing to enter the populations gene pool and no evolution. No heredity and there would be no variation in populations and the first environmental challenge would carry your population to extinction.
What are the four things that must happen for natural selection to occur?
For natural selection to occur, there must be genetic variation present in a population, some of which is heritable. This variation must lead to differences in survival and reproduction (differential fitness). Individuals with advantageous traits must pass those traits on to their offspring. Over time, these advantageous traits become more common in the population.

What helps heredity happen?
Heredity is the process at which traits are passed from parent to offspring.

What must happen for evolution by natural selection to take place?
For evolution by natural selection to occur, there must be genetic variation within a population, some of which must be heritable. The environment must exert selective pressure on the individuals, favoring those with advantageous traits that increase their chances of survival and reproduction. Over time, these advantageous traits will become more common in the population due to differential reproductive success.
