Gametes are sex cells - sperm and egg. Other cells are somatic cells - regular body and organ cells. Also, gametes have half the number of chromosomes as somatic cells do. This is because, when the zygote is formed (sperm and egg form together) they take their chromosomes together to make the number of chromosomes a somatic cell has.
What else can I help you with?
True or false the ordered arrangement of chromosomes in gametes is the same as they were in the parent cell?
False. During meiosis, the process of cell division that produces gametes, the chromosomes are shuffled and randomly distributed, leading to genetic variation in the offspring. This results in a different arrangement of chromosomes in gametes compared to the parent cell.
Where is the production of four haploid gametes from one mother cell completed?
The production of four haploid gametes from one mother cell is completed during meiosis, specifically during meiosis II. Meiosis is a process of cell division that occurs in sexually reproducing organisms to produce gametes with half the number of chromosomes as the parent cell.
How do Meiosis and Mitosis differ?
Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell, resulting in genetic diversity. Mitosis is a type of cell division that produces identical daughter cells with the same number of chromosomes as the parent cell, used for growth, repair, and asexual reproduction.
When are gametes formed?
Gametes are formed during the process of gametogenesis, which occurs in the ovaries (for eggs) and testes (for sperm) in humans. Gametogenesis involves the individual cells undergoing a specialized type of cell division called meiosis to produce haploid gametes with half the number of chromosomes as the parent cell.
What is the difference between meiosis and mitosis?
Meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell, while mitosis is a type of cell division that produces identical daughter cells with the same number of chromosomes as the parent cell.
Do the number of chromosomes in each new cell formed differ from each other?
Gametes contain different genetic information to each other and to the parent cell.
Are gametes produced in meiosis identical to each other but different from parent cell?
No. Each gamete is genetically different from the other gametes and from the parent cell.
True or false the ordered arrangement of chromosomes in gametes is the same as they were in the parent cell?
False. During meiosis, the process of cell division that produces gametes, the chromosomes are shuffled and randomly distributed, leading to genetic variation in the offspring. This results in a different arrangement of chromosomes in gametes compared to the parent cell.
What is the name given to the original cells before it divides?
In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis), and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes (meiosis).
How does mitosis differ in plants?
Plants have a structure called a cell plate which partitions the daughter cell from parent cell.
Where is the production of four haploid gametes from one mother cell completed?
The production of four haploid gametes from one mother cell is completed during meiosis, specifically during meiosis II. Meiosis is a process of cell division that occurs in sexually reproducing organisms to produce gametes with half the number of chromosomes as the parent cell.
How do Meiosis and Mitosis differ?
Meiosis is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell, resulting in genetic diversity. Mitosis is a type of cell division that produces identical daughter cells with the same number of chromosomes as the parent cell, used for growth, repair, and asexual reproduction.
From which cell does human life begin?
A human is created by two gametes, one from each parent, fuse to form a zygote, which is unique from the cells of either parent and is the initial cell that eventually becomes the offspring.
Each daughter cell receives pairs of DNA that differ from those of the parent cell?
Its false... :P
Are offspring of gametes haploid or diploid?
Gametes are haploid. When two gametes unite during fertilization, they form a diploid zygote, genetically unique from either parent, and the first cell of the offspring. The zygote is not really considered an offspring of the gametes, but of the parent organisms that produced the gametes. For example, a human zygote is the first cell of a human baby formed when a sperm from a male and an ovum from a female unite during fertilization. The zygote and subsequent baby are the offspring of the mother and father.
What Process results in the formation of gametes?
Gametes are produced by a type of cell division called meiosis. Meiosis results in four daughter cells each with half the number of chromosomes of the parent cell.
How is the chromosome number affected by cell division?
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.
