A recessive, sex-linked trait in humans is the result of a gene located on the X chromosome. If a man with the trait has children with a woman who neither expresses nor carries the trait, how will the children be affected? a) all of their daughters and none of their sons will express the traitb) half of their daughters and all of their sons will express the traitc) half of their sons will express the trait, but none of their daughters willd) none of their children will express the trait, but their daughters will be carriers
Answers
answer and explanation
X-linked recessive traits that is found on the male will result in the X chromosome from the man carrying the trait and so all the offsprings that have the male x chromosome will carry the trait.
therefore non of the sons will carry or express the trait while all the daughters will express the trait
the correct answer is a.
this is because the daughters will have one x from the father and one x from the mother while males will only get the Y chromosome from the father and not the x chromosome

While working in a genetics lab over the summer, you isolated a true-breeding strain of wingless Drosophila. After sharing your results with your mentor, you learn that six other true-breeding strains of Drosophila with the same mutant phenotype have been isolated independently in your lab. Your mentor asks you to determine if the mutants belong to the same complementation group. What is true about flies that belong to the same complementation group?
a. They all have the same mutation in the same wing- development gene. All flies in a complementation group have identical DNA sequences for this gene.
b. They all have some mutation in the same wing-development gene. Each strain may have a different mutation, but the same gene is mutated in all trains in a complementation group.
c. They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Answers
Answer:
C: They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Explanation:
From the situation of the question given, we can say that the true statement about flies that belong to different complementation groups is option C primarily because Strains existing in different complementation groups obviously would have mutations in different genes.

Answers
Answer:
Commensalism
Explanation:
The trees are not being harmed by the ferns' attachment, but also do not gain anything from the relationship, The ferns gain a supportive, stable environment. Since one organism has a positive gain while the other has no advantage in the relationship, it is commensalism.
Commensalism is a type of relationship in which one organism benefits from the association, while the other organism is unaffected. In this case, the epiphytic ferns benefit from the support provided by the trees, while the trees are not affected by the presence of the ferns.

The above figure gives the cost figures for Jones Farm which producees wheat and sells it in the competitive market for wheat. The quantity of wheat produces in the figure is in the thousands of bushels.
At the market price of $10 for wheat Jones farm will reduce a thousand bushels of wheat in the short run, Jones farm will produce 4,000 bushels of wheat in the quick run and make earnings of $10,000.
To answer this question, you need to discover the income-maximizing output stage for Jones Farm, that is wherein the marginal revenue (MR) equals the marginal cost (MC). Since the market rate of wheat is $10 and Jones Farm is a fee-taker in an aggressive marketplace, the MR is likewise $10.
Looking at the discerning, you could see that the MC curve intersects the MR line at 4,000 bushels. This manner that Jones Farm will produce 4,000 bushels of wheat in the quick run to maximize its income.
To find the profit, you want to subtract the full value (TC) from the full revenue (TR). The TR is manufactured from the fee and the amount, which is $10 x 4,000 = $40,000.
The TC is given by the TC curve at 4000 bushels, which is $30,000. Therefore, the income is $40,000 - $30,000 = $10,000.

Tremendous amounts of water flow steadily over Niagara Falls, which straddles the border of New York and the Canadian province of Ontario. The water moves at speeds ranging from 2 to 3 feet per second. Over time, what will most likely happen to the rock wall behind the falls?
Answers
Explanation:
Given details=
Water flowing at the pace of 2 to 3 feet per sec
It must be understood that flowing water act as an erosive agent here.
As the water flows, it carries with itself erosive tools which erode the rock surface. Since the speed of water is considerable, the erosion is quite significant. Due to the erosive action of the river, the rock wall would be continuously eroded starting from the tip and in turn, would recede backwards (in the upstream direction).
The water will weaken the rock wall. Therefore, the wall will gradually crumble or wear away.

Why do some cells divide faster than others and some cells do not divide after they are formed? Into which group does cancer fit, and why? Justify your answer.
Answers
Answer:
Some body parts, for example, such as muscles, red blood cells, nails, skin, and hair, wear out and/or they die, and therefore they are constantly replaced. To replace the worn out parts and dead parts, there is need for cell division. Other body parts last longer. For example, the liver will last as long as a person lives, and in fact liver failure is one way a person will die. Liver cells are normally not replaced, and therefore there is normally no cell division in the liver. Cell division in these body parts would simply make them bigger and bigger and that may result in illness or even death. In fact, cancer cells are cells that should not be dividing but they continue to divide non-stop because something went wrong.

In a community, it was observed that 25% of the individuals have blue eyes.
Assuming that eye color is controlled by a single gene with two alleles, and that brown eyes are dominant to blue - what is the frequency of the heterozygote? Round your answer to 4 decimal points (and do not forget the leading zero before the decimal).
Answers
the frequency of the heterozygote (Bb) in the population is approximately 0.4431, or 44.31%. To determine the frequency of the heterozygote, we first need to determine the frequency of the blue-eyed homozygote and the brown-eyed homozygote.
Given that 25% of the individuals have blue eyes, we can infer that the frequency of the blue-eyed homozygote (bb) is 0.25, or 25% (since blue is recessive). Therefore, the frequency of the brown-eyed homozygote (BB) can be calculated as 1 - 0.25 = 0.75, or 75%.
Now, let's denote the frequency of the heterozygote (Bb) as p. Since there are only two alleles in the population (B and b), the sum of the frequencies of all genotypes must equal 1.
The frequency of the heterozygote can be calculated using the equation:
2pq + p^2 + q^2 = 1,
where p represents the frequency of allele B, and q represents the frequency of allele b.
Since brown eyes are dominant, the frequency of the brown allele (p) can be calculated as the square root of the frequency of the brown-eyed homozygote (BB), which is 2*0.75*0.25
Therefore, the frequency of the heterozygote (Bb) can be calculated as:
2(0.866)(0.134) + (0.866)^2 + (0.134)^2 ≈ 0.4431.
Rounding this value to four decimal points, we get a frequency of approximately 0.4431 for the heterozygote.
