Answer:
Option C
Explanation:
Let the allele for black color be "B"
and the allele for white color be "b"
Since after F1 generation all the offspring have black body with white speckles throughout their feathers.
Thus the allele for black and white show co dominance.
Genotype of parent after F1 generation would be Bb for speckled chickens
Cross between two specked adults will produce -
Bb x Bb
BB, Bb, Bb, bb
Out of four offspring 1 is black (BB), 1 is white (bb) and two are speckled (Bb)
Thus 50% of the offspring will be speckled, 25% will be black, and 25% will be white.
Option C is correct

Explanation:
Charles Darwin was a British naturalist who proposed the theory of known to everyone as 'The Theory of Evolution' through natural selection.
The answers are: Timber industry, paper industry, furniture industry.
These three industries depend on the trees so that they are able to make products. The timber industry uses the chopped trees, the paper industry uses the cellulose from the trees as it's basis for production, and the furniture industry makes it's products from certain types of tree. So stricter rules would mean big economic blows for this industries.
