Allele that causes yellow eyes (Y) is
dominant over the allele that causes orange eyes (y)
Y = 85% = 0.85 and
y = 100% - 85% = 15% = 0.15
f(y) = square root of y = √y = √0.15 =
0.387
frequency of the allele that causes
orange eyes = 0.387
Once we know the value of y, Y + y = 1
Putting the value of y, we get
Y = 1 – 0.387
<span>Frequency of the dominant allele that
causes yellow eyes = 0.61</span>
A theory of evolution that states that a species evolves in spurts of rapid change and then goes through periods of no change is known as <span>punctuated equilibrium.</span>
Answer:
yes it is a useful mechanism
I believe the answers are A. C. D.
The correct answer is an accumulation of microorganisms in deep marine environments.
Chalk rock refers to a pure form of limestone produced in tropical and warm seas about 100 million years ago in the Cretaceous period. The microscopic marine algae known as coccoliths thrived in the ancient seas. Their shells were comprised of calcite. With the death of the algae, their bodies sunk to the floor of the sea and sediment of chalk got deposited.
Over many years layers of chalk sediment got deposited and resulted in compaction of loose sediment into solid chalk rock.
