The correct option is A.
From the passage given above, it can be seen that the author used the illustration of green house and its mechanism to show us the way in which the atmosphere works.

Answer:
Gentoype of F1: all Bb
Phenotype of F1: black
Genotypes and phenotypes of F2:
1/4 BB - black fur
1/2 Bb - black fur
1/4 bb - brown fur
Explanation:
Black fur (B) is dominant over brown fur (b).
A true breeding black dog will have the genotype BB.
A true breeding brown dog will have the genotype bb.
If both of them are crossed:
BB x bb
F1 progeny: All Bb with Black fur.
At F2:
Bb x Bb
Progeny:
1 BB - black fur
2 Bb - black fur
1 bb - brown fur
<em>Hence:</em>
<em>Gentoype of F1 = all Bb</em>
<em>Phenotype of F1 = black</em>
<em>Genotypes and phenotypes of F2:</em>
<em>1 BB - black fur</em>
<em>2 Bb - black fur</em>
<em>1 bb - brown fur</em>
