Explanation:
Cell culture is the process by which cells, whether prokaryotic or eukaryotic cells, can be grown under controlled conditions. In practice, the term "cell culture" is normally used in reference to the culture of cells isolated from multicellular eukaryotes, especially animal cells. The historical and methodological development of cell culture is intimately linked to the cultivar peptides of tissue culture and organ culture.
Animal cell culture began to be a routine laboratory technique during the 50,1 years but the concept of keeping living cell lines separate from the tissue of origin was discovered in the 19th century.
The first steps a scientist would do when starting a scientific experiment is to: question, do background research, and construct a hypothesis.
Answer:
Incomplete dominance
Explanation:
The traits in the organisms are controlled by the genes which are present in the form of two alleles on the chromosomes. Each allele represents the variant of the trait which is determined when these alleles unite during sexual reproduction.
The allele can be dominant when it shows its effect or it can be recessive when it is suppressed during fusion.
In the given question, the studied trait is the pattern of the hair which is present in two variants: the curly hair and the straight hair. When the parents for these traits were crossed they produced offspring which was intermediate between the curly and the white hair. This intermediate trait shows that neither of the two alleles which control the trait is dominant and the trait blended. This natural process is known as incomplete dominance.
Thus, Incomplete dominance is correct.
