X-linked disorder is a recessive autosomal disorder, which means that
There is a 1 in 4 chance (25%) of having a child who is unaffected.
There is a 1 in 4 chance (25%) of having a child who is affected by the condition. These children have two copies of the gene that do not work correctly.
There is a 1 in 2 chance (50%) of having a child who is a carrier of the condition. These children have one working copy of the gene and one copy of the gene that does not work correctly.
Answer:Succession as progressive change in an ecological community. Primary vs. secondary succession. The idea of a climax community.
Explanation:
Viruses need to be inside a living thing (of course the living thing has to have the right temperature which most living things do) . When they're inside a living thing they start injecting the host's cells with its DNA in order to make more copies of itself which allows the virus to spread. So basically viruses need to be inside something living.
Answer: a) rarely occurs in highly connected metapopulations
Answer:
32%
Explanation:
According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%
That is, A + T + G + C = 100%
Where A=T and G=C i.e the proportion of each base pair is equal.
Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:
18 + 18 + A + T = 100
A + T = 100 - 36
A + T = 64
If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32
Hence, Adenine contains 32%, likewise Thymine.
