"Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA
Dima020 [189]

Answer:

G - 21%

T - 29%

A - 29%

Explanation:

Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.

From the information given, C is 21%

Therefore G is also 21% of the genome as  C is bound to G, the therefore are the same proportion.

C and G make up 42% of the genome (that 21% + 21%).

The remaining 58% (100%-42%) is made up of A + T

Similarly the proportion of A is equal to that of T,

Hence A is 29% (half of 58%) and T is 29%.

Dad: TtBb

Mom: ttbb

You have to use distribution for dihybrid crosses.  Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait.  So for example with Dad, I will number the traits:

T(1)t(2)B(3)b(4)

To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb.  Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.

Cross:

                 tb

TB           TtBb

Tb           Ttbb

tB            ttBb

tb            ttbb

The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue

What makes archaeology a science rather than a pseduoscience
Sliva [168]
Archeology is a science because it is based on real facts and empirical research including research and scientific methods. It would be pseudoscience if it was based on belief, magic, supernatural things, or anything similar.
