Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)

-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)

search "DNA base pairs" and go to images for better understanding

1. In pea plants, tall (T) is dominant to dwarf (t). Show the cross
MA_775_DIABLO [31]

Answer:

Tt - 2/4 = 1/2 or 50%            Heterozygous TALL

tt - 2/4 = 1/2 or 50%             Homozygous Dwarf

Explanation:

So let's make a Punnett for this so you can see what the outcome is yourself:

Tall is <u>dominant</u> - T

Dwarf is <u>recessive</u> - t

Heterozygous means that they have one of each allele. The genotype of one parent would be then Tt.

***It is heterozygous tall because Tall is a dominant trait so if it is accompanied by the recessive trait dwarf, then the Tall allele would mask it.

The other parent is a dwarf plant. The genotype would then be tt.

*** Now for a recessive trait to appear, it should not have a dominant trait mixed with it, which could mask it. The result then is homozygous recessive or homozygous Dwarf.

So now that we know the genotypes of the parent plants, we can put it into a Punnet:

    t      t

T  Tt   Tt

t   tt    tt

As you can see, out of the 4 outcomes we have:

Tt - 2/4 = 1/2 or 50%            Heterozygous TALL

tt - 2/4 = 1/2 or 50%             Homozygous Dwarf
