PP- purple homozygote
pp- white homozygote
Pp- purple hetrozygote
If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)
Now, if those offsprings cross with each other: Pp x Pp
results:
1/4 would be purple homozygote -> PP
1/4 would be white -> pp
2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)
Answer and Explanation:
Platyhelminthes are mostly worm like organisms that are dorsoventrally flattened, meaning they look like a leaf and this is why they are coined names like the Tapeworm, Flatworm, Fluke and Planarian.
Most Platyhelminthes are parasites on other animals but only the Turbellarians are mostly non-parasitic. A few species are commensalists, or mutualists living with other larger organism.
They are classified into:
- Class Turbellaria
- Class Monogenea
- Class Trematoda
- Class Cestoda
Answer: British authorities based their colonial commercial policies on the theory of MERCANTILISM.
Explanation: Mercantilism is the system whereby a country amass wealth for itself at the expense of another country. The prosperity of a nation depends upon its supply of capital, and that the global volume of trade is unchangeable. This is done by increasing export significantly and reducing imports. It was used by the British to significantly amass wealth by importing commodities to Africa in exchange for gold and other precious metals.
