Mitochrondria of the eukaryotic cells.
<span>As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA. <span>

What is modern genetic techniques?
Arlecino [84]
Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells.

In the the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At anot
Irina18 [472]

Answer:

15

Explanation:

According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.

Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.

Vestigial wings, red eyes = 80 : recombinant

Normal wings, purple eyes = 70 : recombinant

Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100

= [(80+70)/(420+80+70+430)]*100

= (150/1000)*100

= 0.15*100 = 15cM
