Answer:
your answer will be C).Nerve cell
Explanation:
Answer:
75%
Explanation:
The autosomal gene for baldness has two possible alleles: Hb (baldness) and Hn (nonbaldness).
A man and a woman, both heterozygous <em>HnHb,</em> have a son. Each parent produces gametes <em>Hn</em> or <em>Hb</em>.
The possible genotypes of their children, resulting from the combinations of those gametes, are:
In males, the Hb allele is dominant. Therefore, their son has a chance of 3/4 = 0.75 = 75% of having the Hb allele which determines baldness.
<u>Necessary for natural selection:</u>
It is the process in the evolution. It explains the nature and it is responsible for the evolution of adoption in the organisms to their environment. The four types of the natural selection are reproduction, heredity, variation in fitness and the variation in the individual characters among the member in the population.
It is the important factor to analysis the environment and reproduction of the organisms. The offspring are resemble same as their parent in the natural selection.
The two DNA strands unwind from one another during semi-conservative replication, and each serves as a template for the synthesis of a new, complementary strand. Two DNA molecules are produced as a result, each with one original and one new strand.
The act of duplication is referred to as replication. DNA replication is the first step in inheritance in molecular biology. The central dogma explains how the DNA replicates itself, codes for the RNA during transcription, and then codes for the proteins during translation.
On several sources of replication along the DNA template strand, DNA replication takes place (antinsense strand). One original strand and one freshly synthesized strand are included in every copy. Although it should be guaranteed that both copies are identical, Each strand of the double helix would act as a template for the manufacture of a new strand, according to the structure of DNA (which was discovered by James D. Watson and Francis Crick in 1953). The process by which freshly created strands united with template strands to create two double helix DNA molecules was unknown.
