Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. What is the probability that a female child of Charles and Marie would suffer from hemophilia?a. 0 percent
b. 25 percent
c. 50 percent
d. 100 percent

Answers

Since hemophilia is an X-linked recessive disorder, the probability depends on the X alleles.
So, if father has dominant allele (H), the probability that a female child would suffer from hemophilia (genotype: hh) is 0%, no matter of mother's genotype:

Father Mother
Parents: H x Hh
Daughter: HH or Hh

Father Mother
Parents: H x HH
Daughter: HH

Father Mother
Parents: H x hh
Daughter: Hh or Hh

But, if the father has recessive allele, the probability that a female child would suffer from hemophilia (genotype: hh) will depend on mother's genotype.
If mother is dominant homozygous, there will be 0% of possibility:
Father Mother
Parents: h x HH
Daughter: Hh

If mother is recessive homozygous, the possibility is 100%:
Father Mother
Parents: h x hh
Daughter: hh

If mother is heterozygous, the possibility is 50%:
Father Mother
Parents: h x Hh
Daughter: Hh or hh

Answer:

It's 0%

Explanation:

It's 0%

If a cell has 18 chromosomes how many chromosomes would each daughter cell have after mitosis

Answers

During mitosis, the cells divide and multiply into two. So multiply 18 by 2 and the daughter will have 36 chromosomes.

What was signiﬁcant about the fossils Darwin found?

Answers

finding evidence such as Giant Sloths, breeds of horses, and hippos in environments which no longer had those existing animals was proof that survival of the fittest was important in climate changing locations.

The fossils discovered by Charles Darwin were effective when studied for evolution. These significantly proved the concept of survival of the fittest.

The phrase "survival of the fittest" was coined from Charles Darwin's evolutionary theory. He described how to describe the entire mechanism of natural selection and fittest meaning in this theory. Charles Darwin proposed the idea of the "survival of the fittest," which states that organisms that are most adapted to their environment have a higher chance of surviving and reproducing.

Examining reproductive success will reveal whether this biological notion of fitness is successful. The phrase "survival of the fittest" is best understood in Darwinian terms as "survival of the form that in successive generations will leave most copies of itself." The survival of the fittest theory, which stated that organisms better suited to their environment are more effective at survival and reproduction, first gained popularity in Charles Darwin's "On the Origin of Species" during its fifth season.

Therefore, the fossils were a proof of survival of the Fittest.

Every atom of the blank carbon has 6 protons

Answers

Explanation:

An element is defined as a substance that consists of same number of atoms with same atomic number.

An element by any chemical means cannot be broken down into its simpler molecules or substances.

Atomic number means the number of protons present in an atom.

Therefore, every atom of the element carbon has 6 protons.

How does the principle of independent assortment apply to chromosomes

Answers

The principle of independent assortment applies to chromosomes because it is the chromosomes that sort independently, not the genes. And the reason that the genes don't sort independently is because the genes are linked to the chromosomes.
