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
C.
the skeletal muscles are attached to the bones which are partly controlled by the central nervous system.
Answer:
A
Explanation:
new combinations of alleles from both parents
Negative: Blood Glucose. The pancreas is releasing more and more insulin in order to get glucose levels in the blood back to a set point.
Positive: Estrogen levels. The anterior pituitary releases estrogen at different levels and the levels fluctuate.
The correct option is D.
When one is talking about comparing, one is referring to noticing the distinctions or differences between two things. In the question given above, sound quality is the factor that is been compared. To compare sound quality of piano, two pianos are needed. The sound quality is compared by playing the same note on two different pianos at the same volume and then decide on the piano whose sound quality is better.
