In a dihybrid cross, the ratio of the offspring is
<span>9-homozygous dominant for both traits
3-dominant for one trait and recessive for the other)
3 -</span>dominant for one trait and recessive for the other
1 - <span>homozygous recessive for both traits
Therefore there will be one-sixteenth of </span>homozygous recessive for both traits( 9+3+3+1=16) of a 100 flies in the next generation, or more precisely 6,25.
4^3 = 64
There are 64 ways to arrange the four bases (Adenine, Thymine, Cytosine, and Guanine) into triplets (include repeats of bases as well, for e.g. AAT).
Just in case you are confused by my use of Thymine above, one thing to note is that Thymine will be replaced with Uracil in RNA.
Hope this helps! :)
The answer is C. A foodhandler sneezes into a tissue before handling food
Answer:
d) polyps; calcium carbonate
Explanation:
The Acanthaster planci It is a kind of invasive starfish, which destroys corals: it has poisonous spines and feeds on coral polyps at the expense of the reef.
On the other hand, CO2 reacts with water, forming carbonic acid and reducing the available calcium carbonate, an essential element so that marine organisms, from clams to hedgehogs, can form their skeletons and shells.
