What other actions result in variation and diversity in the offspring?
crossingover,independent assortment segregation, random fertilization (all of the above ---- ----
What effects does union of haploids in fertilization have on genetic diversity?
Fertilization is random and the haploids are male and female gametes, sperm and eggs. So, genetic diversity is enhanced greatly because random fertilization comes after the independent orientation of male and female chromosomes plus crossing over in meiosis. So, statistically speaking, there are myriad variations that can come out of haploid random fertilization and so great genetic diversity is also enhanced here.
Why meiosis gives 4 different gametes?
Because of the crossingover and independant assortment happens in metaphase1.
What the ways new genetic combinations are formed during meiosis?
Crossing-Over- Chromatids exchange genetic material.Independent Assortment- The random distribution of homologous chromosomes during meiosis.Random Fertilization- Adds genetic variation. The zygote that forms is made by the random joining of two gametes. Because fertilization of an egg by a sperm is random, the number of possible outcomes is squared.
How does sexual reproduction result in a larger variety of possible gene combinations?
Basically, in three ways. Independent orientation of the chromosomes in meiosis. Crossing over in chromosomes in meiosis. Random fertilization; the random mathching of any sperm/egg combination in fertilization.

How genatic material can be rearnged during meiosis?
By crossingover.

Are mitochondria and chloroplast important for fertilization?
Indirectly, yes because everything including fertilization requires energy for sperm to reach there and to initiate the fertilization. However, they are not not directly related or important contributors of fertilization.
Why meiosis gives 4 different gametes?
Because of the crossingover and independant assortment happens in metaphase1.
How do independent assortment crossing over and random fertilization affect the rate of evolution?
They will determine how the fertilization will occur. These can allow for some interesting changes to occur with the different plants.
Why are desivable traits not always passed to offspring?
Fertilization involves a random selection of alleles which are combined.
Why is fertilization important in plants?
so they grow
Why are important in random variables?
It might help if you specified why WHAT was important in random variables.
Which type of fertilization could result in Turner syndrome?
Chromosomal disjunction during meiosis leaving one of the gametes that meet in random fertilization short an X chromosome is the simplest fertilization mishap that results in Turner's syndrome. One X chromosome.
What are Independent orientation of chromosomes at metaphase you and random fertilization most like?
shuffling cards and dealing out hands of poker.
The calculation of offspring includes only variation resulting from?
crossing over, random fertilization, and an independent assortment of chromosomes
