When two gametes fuse, they form a zygote through a process called fertilization. This fusion combines the genetic material from the two gametes to create a new, unique organism with a full set of chromosomes. The zygote will then undergo cell division and development to eventually grow into a mature individual.

What is the meaning of a haploid?
Cells with a full set of chromosomes are Diploids. Cells that contain unpaired chromosomes contain half the set of chromosomes and are called Haploids. Gametes are reproductive cells (sperm and eggs) that are haploids which are produced by the process meiosis.
Why meiosis and gametogenesis are always interlinked?
Meiosis is the process by which the nuclei of certain somatic cells reduce the number of chromosomes by half, in order to produce gametes, or sex cells. The production of gametes is known as gametogenesis. Gametes must have only half the normal number of chromosomes (a condition known as haploid) so that when two gametes (an egg and a sperm) combine, the resulting zygote (fertilized egg) will have the full number of chromosomes-a condition called diploid.
What sequence best represents sexual reproduction in order?
1. gametes - zygote - fertilization - embryo 2. fertilization - zygote - gametes - embryo 3. zygote - gametes - fertilization - embryo 4. gametes - fertilization - zygote - embryo answer is 4. gametes-fertilization-zygote-embryo
What is produced from diploid germ cells by meiosis?
Meiosis produces haploid gametes from diploid germ cells. This process reduces the chromosome number by half, ensuring that when gametes combine during fertilization, the resulting offspring will have the correct number of chromosomes.
What are the 2 human gametes called?
sperm and ova (eggs)
What is the definition of a haploid cell?
A haploid cell is a cell which contains one set of DNA. Most cells have 2 full sets of DNA. Gametes (found in sex cells: sperm and egg cells) are gametes. It is important that they have only one set of DNA because, when the egg is fertilised, the two gametes fuse together to make a zygote with the full 2 sets of DNA.
What are the possible gametes for AAA AAA?
A gamete is haploid (1N) so 'Aa' & 'AA' are diploid and during cell division (mitosis) gametes are formed and then 2 gametes merge together to make a diploid (think of sperm and egg, each is haploid or 1N, when fertilization occurs the egg and sperm form 1 cell that is 2N or diploid). So the possible gametes for 'Aa' would be 'A' & 'a' while for 'AA' the only gametes possible are 'A' If the question is asking what the possible gametes are for 'AaBB' the haploid (gamete) can be 'AB' or 'aB'
What process produce one gamete?
The process that produces one gamete is called meiosis. During meiosis, a diploid cell undergoes two rounds of division to produce four haploid cells, each containing half the number of chromosomes as the original cell. These haploid cells are gametes, which are reproductive cells like sperm or egg cells.
How many male gametes are transfered to ovule in gymnosperms?
2 male gametes
What is type of fertilisation?
There are broadly 2 types of fertilisation - 1) Internal fertilisation - This mostly takes place in higher classes of animals like humans and mammals. In this the male transfers its gametes into the female body and the male gamete fuses with the female gamete inside the female body 2) External fertilisation - This is mostly seen in fishes. The male and the female both transfer their gametes into the external environment and the gametes fuse outside
Name the 2 human gametes and tell their chromosome number?
The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.
What type of cell division produces diploid cells?
Meiosis produces haploid cells from a diploid cell
What is the definition of the word fertilization?
1. The act or process of initiating biological reproduction by insemination or pollination.2. The union of male and female gametes to form a zygote.3. The act or process of applying a fertilizer.

Why are the ovaries and testes important in the process of producing a new life?
Those are the factories for creating gametes, which are the 2 cells that join to form a fetus which is the begining of the creation of a baby.
What is the difference gamete formation in male animals from the gamate in female animals?
Male animals produce small, motile gametes called sperm through a process called spermatogenesis, which occurs in the testes. Female animals produce larger, non-motile gametes called eggs (or ova) through a process called oogenesis, which occurs in the ovaries. Additionally, while male gametes are continuously produced throughout the reproductive lifespan, female gametes are typically formed before birth and released periodically during the reproductive cycle.
