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 cell cycle is regulated at the molecular level by a set of protein known as CYCLIN . Cyclin are a core regulator of the cell cycle. They are group of related proteins and four different types have been identified in humans. Each cyclin is associated with a particular phase of the cell cycle.
Answer:
Indices are used to study fossil specimens and compare them against each other. They are based on concept of ratio hence better than simple measurements when it comes to comparative analysis. They compensate for the problems caused by other variable factors like size or specimen.
For example, to estimate if an organism is long or round headed simple measurement of cranial length or breadth can be done and the result can be given according to the selected parameter. However some specimens will have longer breadth than length and some will have longer length than breadth. So, it is better to measure both the parameters and find out their ratio. Hence, cranial index is used which is given by: (Cranial breadth/Cranial length)*100.

In creating golden rice, Potrykus and Beyer needed to insert genes that would make the ... During which stage of genetic engineering does the scientist add DNA pieces
Explanation:
Answer:
If a plant cell is placed in distilled water, water will enter the cell and the cell contents will expand. However, the elastic cell wall exerts a back pressure, which will limit the net gain of water.
