What would happen if gametes were not haploid?
"Gametes result from meiosis so your question doesn't make sense."Not necessarily a question that doesn't make sense. My biology professors says that, "Meiosis halves the amount of information present in each cell, from the diploid (or double) complement of information to the haploid (or single) complement of information. Fertilization will later restore the ordinary diploid information content by combining the unique informational contents of the egg and the sperm." If that meiosis steps don't happen, then fertilization doesn't happen properly. Meiosis occurs in immature reproductive cells of sexually reproducing eukaryotes. It halves the diploid (2n) chromosome number, to the haploid number (n) for forthcoming gametes. The two gametes fuse at fertilization and the chromosome number is restored, giving the new individual two sets of chromosomes, one from each parent.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
Why dont offspring of two parents look exactly like either parent?
Because an offspring gets 23 chromosomes from each parent through meiosis
In sexually reproducing species the number of chromosomes in each body cell remains the same from one generation to the next as a direct result of?
Meiosis cuts the genetic material in half. Each gamete contains half the necessary genetic information so when they combine during fertilization, the original body cell chromosome number is created.
Children are born to the same parent are usually very different from each other These differences result primarily from the process of?
meiosis
What is the role of meiosis to sexual reproduction?
Meiosis produces daughter cells with half the genetic material of normal cells. This means that when the gametes from each parent meet, the resulting offspring will once again have the correct number of chromosomes. Meiosis allows half of the chromosomes come from each parent - which is vital for sexual reproduction.
Does meiosis increaase the number of chromosomes in a cell?
No, it halves it. This is because Meiosis is only used in the production of sex cells (gametes), and two gametes are needed for a zygote to be created, and each carries half the normal number of chromosomes. When they join together during fertilization their offspring will carry the normal number of chromosomes.
When fertilization occurs offspring inherit?
One homologous chromosomes in a pair from each parent
What happen to chromosomes during meiosis?
half of each parents' chromosomes go to the offspring
Why is fertilization dependenton meiosis?
Meiosis makes each new cell genetically unique in terms of DNA. This ensures that the offspring of the organism is also genetically unique as the two gametes (sex cells) combine together to give the cell a full set of chromosomes that the cell needs to divide/multiply into a new life.
The process of meiosis and fertilization help ensure the survival of the species by providing each generation with the same number of?
chromosomes
Is crossing over takes place in sperms before fertilization?
Crossing over occurs during fertilization. This is the mixing of alleles from each of the parents in order to make the offspring.

What is the law that states that each pair of chromosomes separates on its own in meiosis?
The law that states that each pair of chromosomes separates on its own in meiosis is known as Mendel's Law of Independent Assortment. This principle states that the inheritance of one trait does not affect the inheritance of another trait, as long as they are located on separate chromosomes. As a result, each pair of homologous chromosomes separates independently during meiosis, leading to genetic variation in the offspring.
