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
Answer:
See the explanation below, what is the question you intend to ask anyway?
Explanation:
- Meiosis transmit traits from one generation to the next. It the key process that brings genetic variation into the traits that offspring inherit from their parents. In the life cycle of an organism, meiosis is paired with the process of fertilization.
- Meiosis produces two daughter nuclei with the same number of chromosomes as the parent cell as each other.The chromosomes are re-grouped during meiosis to form new combinations of genes. Genetic reunion is very important as a source of genetic variation.
Answer:
This means that ¾ of the offspring have black fur, while the other ¼ are white. At this point students now have all the information needed to fill in the “predicted percentage” portion of the phenotype Punnett Square. The percentage for the black fur is 75% and white fur is 25%.
Explanation:
Answer: B. Water molecules slow down until they begin to bond together.
Explanation: When water is cooled, energy is removed from the system, and the molecules begin to slow down. When the molecules have slowed suciently, their collisions are no longer energetic enough to overcome their electrostatic attraction, and they begin to bond together. The other answer choices are inaccurate. Since ice is less dense than water, high pressure compresses the ice and actually causes it to melt. (Compression has no effect on water volume.) Cooling has no effect on the shape of individual water molecules.
