This is because during meiosis there is (mostly) genetic variation by means of crossing over, independent assortment and mutations. As two gametes are being fused, the end product will be different from the parent, because the factors mentioned above ensure this.
For a bit more info:
The end product might not always be different as sometimes (in a very rare case), independent assortment and mutations might not occur to the two gametes which are to be fertilised, and if the two gametes both contained chromosomes on which crossing over did not occur, and if these two gametes were to fertilise, then the product would be genetically the same as the parent plant.

How do bacteria have genetic variation thru Transformation Conjugation and Transduction?
Bacteria can achieve genetic variation through three main processes: transformation, conjugation, and transduction. In transformation, bacteria uptake free DNA from their environment, which can originate from lysed cells. Conjugation involves the direct transfer of DNA between two bacterial cells through a physical connection called a pilus. Transduction occurs when bacteriophages (viruses that infect bacteria) transfer genetic material from one bacterium to another, facilitating the exchange of genes. These mechanisms enhance genetic diversity and adaptability in bacterial populations.
Does random alignment of chromosomes during Meiosis produce genetic variations?
In meiosis crossing over may occur at certain points on a chromatid. Crossing over is where variation occurs in allele combination. When a Zygote is formed alleles from mother and father cross over.. this is why you may have some features resembling your father and your mother... or grandma or grandpa... etc... There can be mutations ( messups ) in mitosis but the actual process results in no genetic variation. AP bio
What is the difference between genetic defects and chromosomal abnormalities?
Those terms are synonymous - but genetic defect is more likely to be used to describe a physiological deformity that results from genetics, whereas a chromosomal abnormality might not produce a visible deformity.
How does variation occur?
Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction. If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations. This is how new traits are formed. When the variation is actually more useful than a trait that the organism's parents had, that new variation will be passed along as a survival trait.
How genetic information is kept constant through cell division?
when cell division occurs chromosomes segregate & also the genes present in pairs on then as the genes store genetic information it is kept constant though cell division
What process is responsible for genetic variation?
The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.
Genetic variation occurs when chromosomes are shuffled in and fertilization?
Genetic variation is primarily a result of two main processes: crossing over during meiosis, which shuffles the genetic material on homologous chromosomes, and fertilization, which combines the genetic material from two different individuals. These processes lead to the creation of offspring with unique combinations of genetic information.
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.
What can a genetic mutation cause?
A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.
What genetic mutations can cause?
A genetic mutation can cause a variation, which may be harmless, or may be harmful, depending on where on the DNA molecule it occurs.
Does variation occur in plants?
Much more morphological variation occurs in plants. Genetic variation is the big variation in plants because of polyploidy; this doubling, tripling and halving of chromosome number in the mating of two plants not only leads to great variation in genetic material, but also leads to great speciation in plants.
Why does variation occurs?
Variation occurs because of mutations in the genetic code.Mutaions occur when one of the nitrogen bases are in the wrong spot like if aa is next to each other in the wrong sequence then the mutations occur
What are the three types of variation?
The three types of variation are genetic variation, environmental variation, and genotype-environment interaction. Genetic variation refers to differences in DNA sequences among individuals, while environmental variation is differences in traits caused by external factors. Genotype-environment interaction occurs when the effect of genes on traits depends on the environment.
How does crossing over during meiosis increase genetic variation in a population?
During meiosis, crossing over occurs when homologous chromosomes exchange genetic material. This process creates new combinations of genes, leading to increased genetic variation in offspring.
Which happens first pollination or fertilation?
Pollination. Fertilization is what occurs after pollination.
Does crossing over occur in meiosis?
Yes, crossing over occurs during meiosis. It is the process where homologous chromosomes exchange genetic material, increasing genetic variation among offspring. This occurs during prophase I of meiosis.
Where do pollination is taking place?
self -pollination occurs within the same flower or same plant
