Answer:
The correct answer is : 0.264
Explanation:
The total population of the Soay sheep is : 368 dark sheep + 132 light sheep
= 500 sheep.
Total dark coat sheep ( dark allele represented by D as it is dominant) = 368
Total light coat sheep ( light allele represented by d as it is recessive) = 132
As we know crossing is took place in between true breeding:
DD × dd
F1, Dd ( all are dark coat)
So, the genotype frequency of the homozygous recessive allele is
= 132/500 (by Hardy - Weinberg equation)
= 0.264
Thus, the correct answer is 0.264.
Temperature and pH levels are both correct
Answer:
Its protein; because none of the macromolecules have an 'r group'.
In this passage they talking about water problem and flood, flooding means the covering or submerging of normally dry land with a large amount of water. it means that water is useful but it also dangerous.
In an emergency situation, a person with blood type A could receive type A or type O blood.
Explanation
Blood type A has anti-B antibody in the plasma and O type blood has no antigens. The presence or absence of antigens determine the blood group of individual. The O group is free of antigens and does not trigger an immune reaction in the body and hence are also known as universal donor.
