I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.
We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.
It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
The experiments demonstrate the movement of pollutants through the ground water.
The sand and gravel make up the ground the water represents the ground water. The food coloring represents the pollutants.
There are four different bases that make the DNA molecule:
Adenine, Cytosine, Guanine, and Thymine.
Due to chemical properties of the bases, there are two pairs of bases that are complementary, Adenine and Thymine and Guanine and Cytosine.
So, if we have 16% of Adenine, there must be the same amount of Thymine, since they only appear in a pair.
16% of Adenine + 16% of Thymine - 32 %
the rest of the abundance of the bases can be calculated by subtracting the 32% out of the 100%: 100-32 = 68
So, Guanine and Cytosine make up 68% of the bases, and a half of that number is the amount each of the bases has in the total amount. 68/2= 34
16% Adenine - 16% Thymine
34% Guanine - 34% Cytosine
Answer:
The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.
