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.

Answer from: zenaidazurita1p6bs1d

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.

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
