Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
I recommend to read his article (chapter book):
Jones, JS. (2012). Is Human Evolution Over?. In Evolution 2.0 (pp. 167-176). Springer, Berlin, Heidelberg.
The magnification/power of the eyepiece and the objective lens you are using. I think the eyepiece alone is usually 10x. You just multiply that of the eyepiece and the objective lens.
Answer:
71°
Explanation:
To obtain the angle of impact :
The length of blood stain = hypotenus
The width = opposite
Hence,
Hypotenus = 7.2 mm ; Opposite = 6.8mm
Angle of impact, θ = sin^-1(opposite /hypotenus)
θ = sin^-1(6.8/7.2)
θ = 70.8°
θ = 71°
Answer:
0.08, because for an X-linked trait the genotype frequencies among males are the same as the allele frequencies. Therefore, you would expect about q2 = 0.0064 (or 0.64%) of the female population to be affected and 2pq =0.147 (or 14.7%) of the female population to be carriers.
