Why are small populations more prone to genetic disease

Answers

Answer:

Inbreeding and greater chance of passing deletereous mutations through generations

Explanation:

There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding , that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.

On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.

The small population is prone to the disease more than the large population as the former have less diversity of organism and therefore there are fewer chances of occurrence of an organism that have resistance to the disease.

Further Explanation:

Genetic drift refers to the change in the allele frequency observed in the population due to random sampling. This may occur due to a bottleneck effect or Founder’s effect.

The allele frequency remains constant if the population follows the Hardy-Weinberg equilibrium.

There is more probability of occurrence of diversity in a population of large size that is the large population has an organism that has homozygous dominant allele, heterozygous allele, and homozygous recessive allele. So there is more probability that this population may have an organism having disease-resistant allele than the population of small size.

Double fertilization results in the formation of select one:a. two diploid embryos and a haploid endosperm.
b. one diploid embryo and a triploid endosperm.
c. two diploid embryos.
d. one diploid embryo and a diploid endosperm.
e. two diploid embryos and a diploid seed coat.

Answers

Double fertilization results in the formation of one diploid embryo and a triploid endosperm. Double fertilization is characterized by the formation of two embryos; the embryo proper which is diploid and the fusion product of the central cell with one male gamete which is triploid. This secondary triploid zygote develops into the endosperm.

Explanation:

Your science teacher asks you to build a model of a cell. The model should look like a city, and buildings in the city should represent parts of a typical cell. Each building's real-life function should be like the function of the organelle it represents. For example, the vacuole of a cell, which stores water, could be a water tower in your cell city model.What building should represent the nucleus, and why?A)
factory:manufacturing
B)
city hall:control center
C)
power plant:provides energy
D)
highways and streets:transportation

Answers

Answer: The correct answer is B) city hall:control center.

As per the question, model of cell looks like a city where different buildings correspond to different organelles ( membrane bound subcellular compartments like nucleus, golgi complex, vacuole, endoplasmic reticulum).

Nucleus is a specialized membrane bound compartment that possesses the genetic material ( DNA) of the Eukaryotes ( like plants and animals).

Nucleus controls all the essential activities of the cell by regulating the expression of gene ( segment of DNA corresponding to a particular protein).

Therefore, in the model of cell, city hall;control center represents the nucleus of the cell.

Answer:

B) city hall
