The correct answer to the question above is (c.) natural selection. The natural selection is the process in which individual with useful traits are more likely to survive and produce more offspring with those useful traits.
Correct option A) None.
The male dwarf's father was of normal height; that is, homozygous recessive for achondroplasia. Consequently, the dwarf man of this exercise was heterozygous for the character (say Aa) because this condition is autosomal dominant.
He also has normal vision reason why he is X-NY and X-N which represents the X chromosome with the dominant N allele for normal vision. The woman is color blind and hence a homozygous recessive X-nX-n and of normal height.
Autosomal dominant helps to alleles harbored by any chromosome other than the sexual pair that show complete dominance over the recessive ones. Other diseases such as Huntington's disease, are autosomal dominant.

UULUU 15 is Quritall Streptobacteria null hypothesis Scientic Method - An exemple: In early 2000 a disease appeared in the northeastern United States that had never been seen before. The disease produced a fever and nasal congestion causing the tip of the nose to turn red. The bacteria that caused the disease was isolated and found to be a certain type of streptobacteria. A certain antibiotic called Curitall has been effective against other similar streptobacteria, and so an experiment was set up to test it Curitall would be effective against this certain type of bacteria. On this discussion thread post what the null hypothesis is,
A human cheek cell is thin, flat and has a large nucleus that contains the DNA. Its plasma membrane helps the cell to maintain suitable temperature while giving it its shape. Since it is selectively permeable, it only allows certain molecules into and out of the cell.
