(70pts) Recall the story of Three Blind Mice where the farmer’s wife cuts off the mouse tails with a carving knife. Because of t
omeli [17]

Answer:

What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.

What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.

What else can happen is the trait of tailless cannot  be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore,  there are no chances that tailless mice can born and nature choose it as a favorable trait.

In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.

Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>

Which of the following did you include in your response? Check all of the boxes that apply. Women have two X chromosomes. Recess
Bond [772]

All of the statements are true.

The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.

Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.

In this mode of inheritance, the morbid allele behaves like a recessive trait.

Women heterozygotes are not affected but can transmit the disease; they are said to be conductive of the disease.

The disease is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)
