Yellow = Y

Green = y

Based on the fact that 25% of the offspring inherited two recessive alleles (we know this because in order for a recessive allele to be expressed, it must be homozygous),<u><em> the parent peas had to both be heterozygous. </em></u>

2/4 = Yy

1/4 = YY

In a DNA sample, 15% of the bases are thymine (T). What percentage of the bases in this sample are adenine (A)
Marizza181 [45]
In DNA, thymine binds to adenine, and cytosine binds to guanine. This means that there is an equal amount of thymine and adenine, and there is an equal amount of cytosine and guanine. 

If there is 15% thymine, there should be 15% adenine.

Note that in real life, the percentage of bases won't be 100% equal.
