What type of cells are produced after fertilization occurs and the gametes combine?
The cell created by fertilisation is called a zygote.
What occurs during nondisjunction?
If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
How does meiosis maintain a constant number of chromosomes in the body cells of organisms that reproduce sexually?
The purpose of meiosis is to divide the number of chromosomes in gamete cells (spermatazoa and oocytes) to the haploid number (23 chromosomes). Meiosis ensures the proper number of chromosomes to form a zygote, which is 46 chromosomes (diploid number), during fertilization. Essentially, somatic cells (all other cells except gamete cells) require 46 chromosomes. 23 of these come from the mother and the other 23 from the father. During fertilization, the sperm and oocyte containing the haploid number come together to produce the diploid number. Thus, without mieosis, sexual reproduction would result in zygotes with twice the number of chromosomes (and would continue exponentially)... something that would cause deformities and/or death of the future fetus.
How many chromosomes does a gamete cell have?
75
What occurs when a male and female gamete form to make a new living organism?
its sexual reproduction, aye hit me up on instagram @yaboyiggy thanks

Genetic variation occurs when chromosomes are shuffled in and fertilization?

When does a zygote develop?
A zygote is developed during fertilization - a process that occurs when two haploid gametes (or sex cells) combine. In more general terms, the zygote is formed when the sperm meets the egg.
In sexual reproduction two haploid gametes typically fuse to produce a diploid zygote?
Meosis is the process that brings about the generation of gametes. In meosis, there are two reductional divisions that result in the daughter cells having haploid number of chromosomes.
What happens when gametes fuse during reproduction?
They form a zygote. A zygote is a single cell with the full (diploid) complement of chromosomes. In the case of a multicellular organism the zygote will multiply into a mass of daughter cells called an embryo.
How do meiosis and fertilization keep a species' chromosome number the same?
Meiosis is results in gametes (or sex cells) that have half the number of choromosomes as non-sex cells.This means that when fertilization occurs, each gamete is carrying half the number of chromosomes - so when they combine, you end up with the number of chormosomes found in somatic (non-sex) cells.
What halves the number of chromosomes and results in gametes or spores?
Meiosis is a type of division which results in gametes. This occurs in order for sexual reproduction to proceed.
What occurs during nondisjunction?
If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
What parts of your body does meiosis occur?
it occurs in the gametes, the sex cells. where mitosis occurs in all other cells that have two halves of chromosomes, meiosis occurs in cells which only have one half of the chromosomes.
When fertilization occurs offspring inherit?
One homologous chromosomes in a pair from each parent
What is the site of fertilization in human beings?
In humans, fertilization or union of gametes (sperm and ova) occurs in the anterior part of oviduct and zygote is formed
Why is it important to have haploid gametes?
To prevent the chromosome number from doubling every generation.Sexual reproduction involves two cells (gametes) combining their chromosomes. The process is fertilization, and the product is a zygote.If each gamete has a single set of chromosomes (as happens in humans, most other animals, and many plants) the zygote will have two sets of chromosomes. Whatever the zygote grows into, whether a person, pelican, or pineapple, every cell in the body will have two sets. If the gametes also have two sets each, the next zygote will have four, and so on, until you need a wheelbarrow to carry your chromosomes around!So every life-cycle that includes a doubling of the chromosome number also includes a halving, and that process is called meiosis. Meiosis occurs at different times in different life-cycles. In humans meiosis happens when the gametes are being formed, but in plants it happens when spores are being formed.
