If progeny plants inherited a single whole gene set from each parent, then the aw of independent assortment would not work. this is because two different characteristics would be linked to each other and cannot be independently inherited.
This is explained by the fact that each gene set is present not as a single long thread of DNA, but as separate independent pieces, each called a chromosome. Thus, each cell will have two copies of chromosome, one each from male and female parents. Each germ cell will take one chromosome from each pair and these may be either of maternal or paternal origin. When two germ cells combine, they will restore the normal number of chromosomes in the progeny, ensuring the stability of the DNA of the species.
The genotype of a person with normal red blood cells is usually AA, where both copies of the beta-globin gene are normal. This results in the production of normal hemoglobin and red blood cells.
The cells could have all been produced via asexual reproduction from a single virus cell, or have been rroduced for by normal reproduction. In this sense, the daughter cells would contain the same nucleic aid, as they come from the same virus cell.
Animals cells are diploids, meaning they have 2 copies.
To obtain identical copies of a single cell, scientists make a clone. This involves the process of producing genetically identical organisms or cells by asexual reproduction, such as in cloning techniques like somatic cell nuclear transfer.
Haploid cells contain one copy of each chromosome. This means they have half the number of chromosomes as diploid cells, which have two copies of each chromosome.

Gametes are germ cells. So in germcells the chromosomes are found which carry DNA as genetic material or heriditary material allthough in gamates only half of the no. of chromosomes are found as the two germ cells i.e. of mother and father fused toghter to form zygote which will then having exactlly the same no. of chromosomes as that of normal cells of that species.
a. cancer cells divide uncontrollably. b. normal cells cannot make copies of DNA. c. cancer cells cannot make copies of DNA. d. normal cells divide uncontrollably. (A) cancer cells divide uncontrollably
Down syndrome results when cells receive three copies of chromosome 21.
No, not all normal body cells in humans have the same karyotype. Karyotype refers to the number and appearance of chromosomes in a cell, which can vary among different cell types in a single individual due to genetic diversity or the normal process of cell division.
Another way to say "make copies of cells" is "replicate the cells".
Red blood cells are highly specialized for oxygen transport. They lack a nucleus and instead, contain many copies of hemoglobin. Red Blood cells move single file through the capillaries

If the genetic material is RNA, it will usually be single stranded. Only viruses contain double stranded RNA. The main genetic material in eukaryotic cells (eg. animal cells) is DNA. Single stranded RNA copies of this (known as mRNA) are made in order for proteins to be synthesized.
