Hybrid = having one recessive and one dominant allele
This means that all of the flowers must have the genotype Bb.
Knowing this, let's make a Punnet Square.

As you can see, 3 of these are going to have the dominant trait and 1 is going to have the recessive trait. This corresponds to our 3:1 in our question, meaning that the black seeds must be dominant and the brown ones recessive.
Because they are dominant, the genotype for black seeds could be 
BB <em /><em>or</em> 
Bb.

Answer:Dna template- 5' ACTCCTGAA 3'
3' TGAGGACTT 5' complementary base
Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base. 
Replication occurs in 5' to 3' direction.
For complementary base in DNA Adenine complement thyamine
Cytosine complement Guanine
i.e A-T
 C-G
Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'
