Question: If the chromosome number of a gorilla is 48 before mitosis, what is the chromosome number in each nucleus after the nucleus division has taken place?

A gene is a short length of DNA found on a chromosome that codes for a particular characteristic or protein. Alleles are variations of the same gene. For example, eye colour is the gene but blue.

In species that reproduce asexually, the chromosome number is the same in all the cells of the organism. Among sexually reproducing organisms, the number of chromosomes in the body (somatic) cells is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.

Chromosomes are tiny, threadlike structures inside most cells of every organism, or living thing. Chromosomes carry information about the organism in units called genes. When living things reproduce, they pass their genes along to their offspring.

Chromosome Number Homework

Chromosomal disorders can result from changes in either the number or structure of the chromosomes. Changes in the number of chromosomes happen when there are more or fewer copies of a particular chromosome than usual. Changes in chromosome structure happen when the material in an individual chromosome is disrupted or rearranged in some way.

Chromosome number in seedling progenies is an important trait in understanding the genetics of plants. Curcuma is no exception. Numerical variation in chromosome number in Curcuma germplasm and seedling progenies has been reported by some researchers, among which the investigations of Nair and Sasikumar (2009) are important. They determined.

The second type of division produces body cells with a normal chromosome number of 46 (diploid). This type, termed mitosis, is indicated by box 2 and 3 in the figure. A fertilized egg produces a(n) zygote, the combination of sperm and egg cells, resulting in a normal chromosome number.

The chromosomes are the genetic storage material of all the eukaryotes, and the number varies from 10 to 50 chromosomes: e.g. human have 23 pairs of or 46 chromosomes. Although it is more about DNA, proteins also form a part of chromosomes. Duplicated chromosomes are known as chromatids that are joined together by centromere.

Crop Plant Ploidy Number Chromosome Number Banana 3n 33 peanut 4n 40 potato 4n 48 oats 6n 42 wheat 6n 42 The ploidy number indicates how many sets of chromosomes are present, where n is the number of chromosomes in one set. The chromosome number indicates the total number of chromosomes present in one cell (except gametes).

Chromosome and Chromatid Numbers during Mitosis and Meiosis. A topic in biology that many students find challenging (and is known to appear on the DAT) is the number of chromosomes and chromatids present during the various stages of meiosis and mitosis in eukaryotes.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique. The term chromosome comes from the Greek.

Chromosome Number Changes Chromosomal variation is widespread in plants. Within a given genus or species the plants may have small differences in chromosome numbers (which is the characteristic number of chromosomes contained in the cell nucleus of a given species).
