We will use the Hardy-Weinberg equation ; p2 + 2pq + q2 = 1
q2 represent the frequency of the recessive trait in the population which is 400/10000 = 0.04. Then find frequency of the recessive allele.
q = 0.2. While we understand that p+q =1 ; p = 1-q ; p = 1-0.2 =0.8.
2pq represents the frequency of heterozygous trait in the population. Therefore 2*0.8*0.2 =0.32
0.32*10000 = 3200
Answer:
The believe the correct answer is option E.
Mesozoic Era is the second of the Earth's major era geologically of the Phanerozoic time. It means middle life in Greek. The climate during this time was warm and had less difference in the temperature today thus the answer is a. About as warm as present.
Answer:
The correct answer is -
P1: SSyy
p2: ssYY
Explanation:
In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.
It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.
