The act or process of initiating biological reproduction by insemination or pollination. The union of male and female reproductive cells (gametes) to produce a fertilized reproductive cell (zygote). Fusion of a sperm cell with an egg cell to produce a zygote when the female sex cell (egg) and the male sex cell (sperm) come in contact. the joining of a sperm and an egg The fusion of the male sex cell with the female sex cell to form an embryo is called fertilisation. The fusion of an egg and sperm to form a zygote
What else can I help you with?
What results from ferilization?
what two DNA come together
What type of division occurs to produce an embryo plant from the diploid zygote formed after ferilization?
Haploid
How did mendel make th F1 generation for his expiriments?
Mendels' f2 generation produce a 3:1 ratio of tall plants. By crossing true tall with true short , homologous chromosomes, he wound up with three types of plants, true tall, true short, and tall with a short allele.

What kind of reproduction does a cheetah have?
It has sexual reproduction - by means of internal ferilization.
Python external ferilization or internal fertilization?
Pythons use internal fertilization.
What type of division occurs to produce an embryo plant from the diploid zygote formed after ferilization?
Haploid
What is a developing plant formed through ferilization called?
The developing plant formed through fertilization is called an embryo.
Is it true that using contraseptive is like killing a human?
No. Absolutely not. Using a contraceptive prevents ferilization of an egg. When you take such a precaution, a life never begins, and therefore cannot be ended.
What is a cell that forms in ferilization?
The first cell to form in fertilization is the zygote. The zygote undergoes cell reproduction in order to form a multicellular embryo, in which all of the cells are genetically identical to the zygote. All of the body cells in the new offspring will, in theory, be genetically identical, unless uncorrected mutations occur.

What is caused by down syndrome?
Down Syndrome (aka trisomy 21) is caused when an extra chromosone number 21 is present. Normally, each cell in your body has two copies of each of the 44 regular chromosomes, one X and another X (in women) or a Y (in men). When sperm and eggs are formed these pairs line up and then are divided into two sets of 23 chromosomes, one of each. In the most common form of Down Syndrome the pairs of chromosone 21 do not seperate making a sperm or egg with two and another with none. If the sperm or egg with two participates in ferilization the result is a cell with 3 chromosome number 21's (2 from one parent and 1 from the other). This type tends to happen more often as women get older. It is not nearly as strongly related to the age of the father. In a less common form one of the parents has a chromosome 21 that is duplicated and stuck to itself and so twice as large (a Robertsonian translocation). The person with this defect may be an apparently normal carrier but produce children (and grand children) with Down's.
What causes downs syndrome?
When a child is diagnosed with DS, this means that they were born with an extra chromosome 21. Giving them a total of 47 rather than 46.This extra chromosome delays physical and educational development.
