Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.
When speaking about pre-molars, we would only contain 8 pre-molars, and this is due because we only contain 32 teeth.
We have : (8 pre-molars)
We have : (12 molars)
We have : (8 incisors)
And for the last part, we would contain : (4 canines).
There is only one structure feasible for a tetrahedral molecule with such a formula, under the supposition that A is in the center of the tetrahedredon. In this case X and Y are in the vertices of the tetrahedron.
If you draw several figures changing the position of the X's and the Y around the center (A), you will see that all are equivalent.
This is the case of the product CH3Cl, named chloromethane, which, for the same reason given above, does not have isomers.
Answer:
<em>What are the allele frequencies in this population?</em>
- Frequency of S = 0.625
- Frequency of s = 0.375
<em>In the next generation of 1000 hamsters, what are the expected genotype frequencies?</em>
- Frequency (SS) = 0.39
- Frequency (Ss) = 0.47
- Frequency (ss) = 0.14
<em>What are the expected number of each genotype in the next 1000 hamsters?</em>
- Individuals SS = 390
- Individuals Ss = 469
- Individuals ss = 140
<em>Have the allele frequencies changed?</em> No, they are the same
<em>Is the population in Hardy-Weinberg equilibrium?</em> Yes, it is.
<em>The expected genotype frequency of Ss (2pq) in the next generation is expected to be: </em>0.469 (option a)
<em>The expected number of smooth fur hamsters (SS) in the next generation of 1000 hamsters is</em>: 390
