Answer:
50% will be normal and 50% will be carriers
Explanation:
Color blindness is a reduced ability to distinguish between certain colours.
The condition is often inherited. Other causes include certain eye diseases and medication. More men than women are affected.
If such a carrier woman with normal vision (heterozygous for colour blindness) marries a normal man (XY), the following progeny may be expected in the generation: among the daughters, 50% is normal and 50% are carriers for the diseases; among sons, 50% are colour blind and 50% are with normal vision.
I say about 40 percent cause say something like this ..
20% of small species of fish
20% of big species of fish
to be equal
20% are bigger
20% are smaller

Answer:
Primary succession occurs in areas without any soil where basically nothing is there. After an event such as a volcanic eruption, pioneer species such as lichens and mosses are able to colonize the land since they can grow without soil and are primitive. Lichens can break down rock to form soil and they can add small amounts of organic matter to the rocks when they decompose to make even more soil. Simple plants like ferns can then grow in the created soil. After these simple plants die, more organic material is added to the soil and the soil thickens, allowing grasses, wildflowers, and other plants to begin to take over. Next, after these plants die, enough nutrients are added to the soil for trees and shrubs to survive. Finally, insects, small birds, and mammals begin to move into the area and form a community, so what was once bare rock can now support a variety of life.
