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
Know whether or not gametes have homologous chromosomes?
Gametes are said to have homologous chromosomes, if they have same genes arranged in same order. During gamete formation meiosis precedes, therefore, individual gamete does not have its homologous counterpart. After fertilization, in diploid nucleus, homologous chromosomes are restored.
What is the purpose of gametes?
To improve Fertilization.
How many chromosomes in rafflesia?
the number of chromosomes present in the somatic cells of rafflesia flower is 12... but as in gametes,gametes are formed by meiosis or reductional division ( in which the number of chromosomes becomes half the parent cell so that after fertilization, the original chromosome count is restored and the organism is identical), the number of chromosomes found in the games of raffleisa will be 12/2 or 6 chromosomes.
What happens at fertilization after gametes experiance meiosis?
The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization
Fertilization occurs when the chromosomes of gametes combine true or false?
false

Which term refers to the process in which two gametes fuse to make one zygote?
fertilization

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.
Fusion of male and female gametes?
Fertilization
The fusing together of two gametes at fertilization is?
Gametes fuse together during fertilization.
What happens at fertilization after gametes experiance meiosis?
The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization
Gametes have what kind of Chromosomes?
Gametes have haploid chromosomes, which means they have half the number of chromosomes of other cells in the body.
After gametogenesis takes place which process restores the diploid chromosome number of the species for the next generation?
In the S phase before mitosis, the chromosomes duplicate into sister chromatids before spearating during mitosis. The number of chromosomes remainds diploid because they double before they are halved.
