Answer:
See the answer below
Explanation:
Let the disorder be represented by the allele a.
Since the disease is an autosomal recessive one, affected individuals will have the genotype aa and normal individuals will have the genotype Aa or AA.
Since the four adults are carriers, their genotypes would be Aa.
Aa x Aa
Progeny: AA 2Aa aa
Probability of being affected = 1/4
Probability of being a carrier = 1/2
Probability of not being affected = 3/4
(a) The chance that the child second child of Mary and Frank will have alkaptonuria = 1/2
(b) The chance that the third child of Sara and James will be free of the condition = 3/4
(c)
(d) If someone has no family history of the disorder, their genotype would be AA.
AA x aa
4 Aa
<em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history </em>= 0
(e)
(f) <em>The chance that a child with alkaptonuria will have an offspring with alkaptonuria if the child's mate has no family history</em> = 0
The correct answer is "transmission electron microscope".
The transmission electron microscope can magnify the organelles of the cell clearly; as in light microscopes wherein most organelles cannot be visualized. TEM works by using a beam of electrons to pass through a specimen to make a clear image. Because of its superior magnification, mitochondrial defects can be visualized easily.
Attached is a sample picture of a transmission electron microscope image of a mitochondria.
Answer:
Estimated size is 1600
Explanation:
Given data:
Size of lake is 250 hectares
Total number of trout who netted is 400
Total number of trout in next week is 200
Total number of trout having fin clip 50
estimation population size is estimated by mark rupture as follow
Estimated population size 
Estimated size
Estimated size is 1600
That would mean that species A, B, and C all came from one tree. Species A and B would be closer related, and also resembling more of each other. While species C would be also related to species A and B but just not as close to either one.
So the answer would be: Species A and B would be most similar, while species C would be related to both species A and B but will have less similarities. <span />
