Why Chromosomes number is used in the identification of species?
Chromosome number is used in species identification because it is a stable and unique characteristic of a species. Variations in chromosome number can indicate genetic relationships between species, and can help distinguish between closely related species. Additionally, chromosome number is often conserved within a species, making it a useful tool for taxonomic classification.
What is the diploid number of chromosomes for a normal bug karyotype?
what is the 2n chromosome number for a normal bug
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
What is the normal male genotype?
It has the same number of chromosomes as an adult, that is 23 pairs.
What is the number of chromosomes in a gemete?
Depends on what species is in questions - different species have different numbers of chromosomes in gametes.
What is the modal chromosome number?
The modal chromosome number refers to the most common number of chromosomes found within a particular species. It is essentially the number that occurs most frequently among individuals of that species.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)

Gametes are diploid so that when fertilization occurs the resulting zygote will have the normal number of chromosomes for the species?
Actually, gametes are haploid, not diploid. This means they contain half the number of chromosomes typical for the species. During fertilization, two haploid gametes (one from each parent) combine to form a diploid zygote, restoring the normal chromosome number for that species. This ensures genetic diversity and proper development.
What ant species has the chromosome number 2n equals 4?
all ants
How many chromosome pairs are in a species with a haploid number of 68?
68 pairs .
