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 diploid number of chromosomes for a normal bug karyotype?
what is the 2n chromosome number for a normal bug
In plants and animals an offspring inherits How Many genes?
The number of genes and number of chromosomes inherited depend on the species. The number of chromosomes a species has is known as the chromosome number. For example, (disregarding polyploidy or polysomy) a human baby has 46 chromosomes, but a horse has 64. Chromosomes usually occur as one of a pair in humans, and so they have 23 pairs of chromosomes. However, it is common in plants to have many sets of chromosomes and so they do not occur in pairs, but in triplets, or as sets of 4, 5 or 6 etc. Some species of strawberries have 7 of each chromosome. The number of genes depends on how long the chromosome is, and each chromosome in each different species will have a different number of genes on the chromosome.

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)

What is it called when a chromosome's number is represented with 1n?
Haploid
Compare the numbers of chromosomes in different species?
The chromosome number is specific for each type of organism. The exact chromosome number must be maintained for the species to continue. This means that as cells reproduce, the new cells must have the same number of chromosomes as did the original cells
