Biología celular o citología: rama de la biología que se centra en el estudio de la estructura y función de las células. Biología del desarrollo: es la rama que analiza cómo es el desarrollo de los seres vivos desde que se conciben hasta que nacen.
A geneticist describes the phenotype of an individual with the alleles dd as homo-zygous recessive. In heterozygous individuals, it is masked by the dominant allele.
<h3>Dominant and recessive alleles</h3>
In diploid organisms, an individual receives two gene forms or 'alleles' for the same gene locus.
An individual is heterozygous when receives two different alleles for the same gene locus, whereas an individual is homo-zygous when receives the same alleles for a gene locus.
In cases of complete dominance, the dominant allele completely masks the recessive allele in heterozygous individuals.

Answer:
B
Explanation:
This involves selectively breeding two or more populations of a species or subspecies with desirable traits that are wanted by the humans. The offspring of the populations will bear the desired traits from the population. Breeding can be done over generations. An example is the breeding a cattle population that is resistant to drought and another that produces more milk. The filial generations will bear both traits.
Answer:
Option (A)
Explanation:
The Inuits refers to those people that live in the Arctic region, such as Greenland, the northern region of Canada, as well as Alaska. The region in which they live can be considered as tundra, which is characterized by the presence of low temperature, dry wind, shorter duration of seasons, and lack of vegetation. This type of region is found in the polar and near-polar areas and in the high altitude areas.
The climate of tundra is very cold, and there occurs the layer of permafrost in the soil, and it does not provide the essential conditions for the growth of plants. The growth of crops is hindered by the shorter season, lack of sunlight and low precipitation.
This is why the Inuits are dependent on hunting for heir survival
Thus, the correct answer is option (A).
