Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Complementary DNA? please help​
topjm [15]

Answer: From top to bottom- T, C, G, A, T, A, T

Explanation:

These are the nitrogenous bases that make up a part of nucleotides in DNA.

There are 4 bases in DNA:

- Adenine

- Guanine

- Thymine

- Cytosine

The bases pair together from A to T and G to C, the way I remember is just reading it as AT GC and it works for me, but you make want to make an acronym if it helps you remember better.

As a result, all you have to do is type in the corresponding base to form the correct base pairs.
