What Has the same number of chromosome sets as a germ cell?
A haploid germ cell has the same number of chromosome sets as a gamete, which is half the number of chromosome sets found in a somatic cell. This enables the gametes to fuse during fertilization to restore the diploid number of chromosomes in the zygote.
What are tetrasomics?
Addition of a pair of chromosomes to a diploid set results in tetrasomic condition. Tetrasomics may be represented as 2N+2. Tetrasomics may arise when two abonormal gametes produced as a result of non-disjuction unite, with each gamete carrying an extra chromosome of the same pair as shown below. AABBCCDD a diploid cell----meiosis and non disjuction AABC Gamete carrying an extra chromosome--- BC Gamete short of one chromosome. Now if this Gamete (AABC) unites with another gamete of the same kind (AABC), we get tetrasomic AAAABBCC.
What happens to the chromosome number during mitosis?
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
How Compared to a body cell a gamete contains?
Gametes have half the number of chromosomes as a body cell because they are haploid, while body cells are diploid. This reduction in chromosome number ensures that when a sperm and egg combine during fertilization, the resulting offspring will have the correct diploid chromosome number.
Two genes are almost always found in the same gamete?
Two genes that are almost always found in the same gamete are probably located near each other on the same chromosome. Crossing over is more likely to occur with genes that are farther apart on the same chromosome.
Do All cells within an organism will have the same number of chromosomes except the gamete?
Yes, all cells within an organism (excluding gametes) typically have the same number of chromosomes, known as the diploid number. This number is characteristic of the species and remains constant throughout most of the organism's cells. Gametes, such as sperm and eggs, have half the number of chromosomes (haploid) to ensure the correct chromosome count is restored upon fertilization.
Is the sex of the offspring of a cow determined by the egg or sperm?
The sex of the offspring is always determined by the sperm: this is the same in pretty well all animal life, including human reproduction. The gamete in a cow always carries the X chromosome. The gametes in a bull carry both X and Y chromosomes, which mean that if the sperm with an X chromosome fuses with the gamete of the cow, the offspring will be female. If the sperm carries a Y chromosome and fuses to the female gamete of the cow, then the offspring will be male.
What is the chromosome number in the daughter cell?
The chromosome number for daughter cells resulting from mitosis is the same as the parent cell.
If 2.2 picograms of DNA could be extracted from a certain number of human muscle cells about how many picograms of DNA could be extracted from the same number of human gamete cells?
Since human body cells (like muscle cells) contain twice the amount of DNA present in human gamete cells, roughly 1.1 pg of DNA can be expected out of human gamete cells
The chromosome number in an egg cell nucleus of a plant is 14 What is the normal chromosome number in a root epidermal cell of the same plant?
The normal chromosome number in a root epidermal cell of the same plant would also be 14. This is because both the egg cell and the root epidermal cell are part of the same plant organism, so they would have the same chromosome number.
The occurrence of a number of genes on the same chromosome?
Linkage.
Do mitosis and meosis have the same chromosome number?
No, mitosis and meiosis do not have the same chromosome number in their resulting cells. Mitosis produces two daughter cells that each have the same chromosome number as the original cell (diploid in humans, for example). In contrast, meiosis results in four daughter cells, each with half the chromosome number of the original cell (haploid in humans), which is essential for sexual reproduction.
