Answer:
27/64 or 0.421
Explanation:
When AaBbCC X AaBbCc :
A_B_C_ = 27
aaB_C_ = 9
A_bbC_ = 9
A_B_cc = 9
aabbC_ = 3
A_bbcc = 3
aaB_cc = 3
aabbcc = 1
Out of the total 64 offspring, 27 will have at least one dominant allele for each of the three genes hence these 27 offspring will show dominant trait for all genes. So the probability of producing a dominant trait for all genes will be 27/64 or 0.421
Extreme climates changes are independent. But some other types are dependent. However, they are too minor to really be included.
Answer:
Smaller populations have a greater chance of having one allele expressed disproportionately.
Explanation:
Genetic drift is defined as the a change in how frequently a gene allele occurs in a given population as a result of random sampling.
This random sampling is similar to having a coin toss that gives heads or tails.
Genetic drift has the tendency of making smaller populations have a greater chance of having one allele expressed disproportionately.
This is because when individuals in a small population mate there is a greater probability that an evolution will have more far reaching effects.
In a large population the effect will be less pronounced.
A. RbOH is a base because its pH is greater than 7.
This statement is correct and points at the compound being a base because an Alkali always has a pH between 7 and 14. Starting from 7 which is a neutral compound neither acidic nor alkaline, the higher the pH value, the stronger the compound is an alkali or a base. The strongest pH compounds are those that have the pH value of 14 and the weakest alkalis are those the pH value of which is closer to 7.
None of the other options fit this criteria.
