What happens to the allels durnig meiosis?
The alleles of 2 or more different gene pairs assort independently of one another.
How does gene shuffling contribute to gene variety int the gene pool?
Gene Shuffling-one of the two main sources of genetic variation(other is mutations) Gene Shuffling happens at the gametes/sex cells formation when the chromosomes line up in the middle at random during meiosis. So that means the 23 pairs of chromosomes we have can produce 8.4 million different combinations of genes. Think of it as to playing cards. Each card represents an allele/trait. When you shuffle the cards, it leads to many different hands(poker) you can obtain. I hope my horrible explanation helps.
What principle states that during meiosis chromosomes are distributed to gametes in a random fashion?
It's the Gene-Chromosome Theory.
Is it true or false that during meiosis the two alleles for each gene stay together?
False. During meiosis, the two alleles for each gene can separate and be distributed to different gametes. This is known as Mendel's law of independent assortment, which allows for new combinations of alleles to be formed in offspring.
Is an allele is a gene from several pairs?
No, not exactly. They are different forms of the same gene.

How do chromosomes gain a extra copy of a gene during meiosis?
chikcen and rice
During meiosis does the 2 alleles for each gene stay together?
They separate
How is meiosis related to genes?
Meiosis allows a cell to form into 4 cells (by meiosis 1 (which is literally mitosis) and meiosis 2 (mitosis without DNA replication)) in meiosis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells. segragation of alleles occur too.
Gene shuffling includes the independent movement of chromosomes during meiosis as well as?
Crossing-over

Explain how meiosis creates genetic diversity in populations.-?
Meiosis creates genetic diversity due to the processes that occur during meiosis. Such as crossing over which creates new gene combinations due homlogous chromosomes swapping or exchanging DNA segments. Independent assortment is also during meiosis and allows the random assortment of homologous chromosomes during metaphase 1.
When does the separation of alleles of a gene happen?
Anaphase I of meiosis
What phase of meiosis do homologous chromosomes cross over?
Crossing over begins early in prophase I of meiosis. At the time, homologous chromosomes Are paired along their lengths. Each gene on one homologue ia alined precisely with the corresponding gene on the other homologue. Source: my science book copy right 2006
How many alleles are there for a trait in a sex cell?
An allele is one form of a gene. Alleles separate into separate sex cells during meiosis.
