I THINK
Neanderthals are the closest extinct relatives of modern humans, and lived in Europe and Asia. Recent findings suggest that Neanderthals were closely related enough to interbreed with ancestors of modern humans— about 1.5 to 2.1 percent of the DNA of anyone outside Africa is Neanderthal in origin
Answer:
Explanation:
using the formula p² + 2pq + 2pr + q²+ 2qr + r² = 1 where p is IA allele is 0.35 and q is IB allele is 0.15.
Thus, the expected frequency of people with type AB blood in this population will be (2pq) = 2 x 0.35 x 0.15 = 0.105
b. The expected frequency of people with type A blood will be p² + 2pr = where r is found using the formular p + q + r = 1 = 1 - (p+q) = 1 - (0.35+0.15) = 0.5
Thus, we have the expected frequency of people with type A blood to be (0.35² + 2x0.35x0.5) = 0.4725.
c. <u> p² + 2pr</u> + <u>2pq </u>+ <u>q² + 2qr</u> +<u> r²</u>
AA AO AB BB BO OO
1850 180 635 2335
frequency of IA- p = (1850 + 180/2) / 5000 = 0.388
frequency of IB- q = (635 + 180/2) / 5000 = 0.145
frequency of i- r = 2335/ 5000 = 0.467.
since r² = 2335, r = √2335 = 48.32
using the formula p + q + r = 1
Answer:
B. Producing Energy
Explanation:
Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
Answer:
What is the main function of chloroplasts in a cell?
Chloroplast houses the chlorophyl that gives green pigment which is used by plant to trap sunlight and undergo photosynthesis
Explanation:
Answer:
The correct answer is- TAAGCCGATAAATGCTAACGGTA.
Explanation:
DNA is a nucleic acid molecule made of two strands. Each strand is made up of nucleotide bonded via phosphodiester bonds. Each nucleotide is made up of- 5C deoxyribose sugar, a phosphate group and nitrogenous bases.
DNA replication produces an exact copy of the DNA molecule through complementary base pairing. The complementary strand is formed by adding nucleotide through DNA polymerase which adds base pairs according to the Chargaff rule. The Chargaff rule states that A will bind T via two hydrogen bonds and G will bind C via three hydrogen bonds.
Therefore, the complementary strand will be-TAAGCCGATAAATGCTAACGGTA
