Answer:
Mutations can create entirely new alleles in a population which changes the allele frequencies of a gene pool.
Answer:
Probability that the son will be:
color-blind = 1/2
blue eyed = 1/8
blue eyed and color-blind = 1/16
Explanation:
Mother : BbXcX
Father : BbXY
Colorblindness is X linked recessive trait hence will be caused when the son has XcY genotype.
XcX X XY :
Xc X
X XcX XX
Y XcY XY
Half of the sons will have normal vision and other half will be colorblind hence, there is 1/2 probability that the son will be colorblind.
Eye color is autosomal trait and blue color will be produced when the child has bb genotype.
Bb X Bb :
B b
B BB Bb
b Bb bb
1/4 of the children will have blue eyes. Since half of the children are expected to be males, 1/4 * 1/2 = 1/8 sons are expected to have blue eyes.
Probability of a son being blue eyed and color blind will be :
1/8 * 1/2 = 1/16
Away from the ganglion The axon of a
ganglionic neuron is called a postganglionic fiber because it carries impulses.
an accumulation of extracellular fibrillar proteins and abnormal
dendrites and axons. A “ganglion”
is essentially a living relay. The inputs are “pre-ganglionic” and the outputs
are “post-gangionic.” Simple.
The correct answer is:
B.) A tapeworm latches itself in the intestines of a rat, feeding off all the nutrients eaten by the rat.
Believe me, I just took the quiz and got the answers back, and I got this wrong because of the answer I got from here was WRONG!!
So happy to help :)
