The random combination of chromosomes resulting from pairing up 1 of the 8.4 million possible chromosome combinations of a sperm with 1 of the 8.4 million possibly chromosome combinations of the egg (due to independent assortment of chromosomes during Meiosis. This comes out to about 70 trillion combinations, which does not even factor in the crossing over of genetic material during Meiosis.

How does the process of fertilization act to increase genetic diversity within a population?
Random fertilization. All the eggs and sperm produced are variations due to crossing over alone, not even considering other processes. The meet and fertilization occurs randomly insuring a good mix of genetic variation. Thus, genetic diversity.
Which term refers to the process in which two gametes fuse to make one zygote?
fertilization
Explain the exchange of chromosome segments between chromatids of homologous or non-homologous chromosomes?
a. crossing over b. independent assortment or c. random fertilization
What does random mean in science terms?
random in science terms means random duhhh. :) random is random in every language or subjects
What is the part of speech of random?
"Random" is an adjective.
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.
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.
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
What occurs when chromatids exchange some DNA and this results in genetic variety?
crossing-over occurs and random fertilization
What other actions result in variation and diversity in the offspring?
crossingover,independent assortment segregation, random fertilization (all of the above ---- ----
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 the process of fertilization act to increase genetic diversity within a population?
Random fertilization. All the eggs and sperm produced are variations due to crossing over alone, not even considering other processes. The meet and fertilization occurs randomly insuring a good mix of genetic variation. Thus, genetic diversity.
What has the author Verne Grant written?
Verne Grant has written: 'Genetics of flowering plants' -- subject(s): Plants, Angiosperms, Genetics, Plant genetics 'The fertilization of flowers' -- subject(s): Fertilization of plants
How do you calculate gene combinations for a given set of genes?
For just random assortment, there are 2 to the power of the number if pairs of chromosomes. In humans, it's 2 to the 23 power. Recombination and random fertilization create even more variations but can not be calculated.
