identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution

nignag [31]

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. Biston betularia, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

What we already know:

All species under normal circumstances will have two sex chromosomes. X and Y, Y is known to be dominant. All females will have two X chromosomes (XX, one X will always be given by the mother), whereas males will have one Y chromosome and one X chromosome (XY, one X will always be given by the mother. The father, on the other hand, could give either an X or a Y, that all depends on what sex chromosome the father's sperm donated.)

So, how many chromosomes do a typical human have? Correct, a typical human has 32 chromosomes and only 2 of them are sex chromosomes. Now we must understand that the sex chromosome carries more than just the one code for the individual sex. That means that the gene codes for more than just the sex.

Building on that knowledge:

Sex-Related Inheritance that differs from sex, is carried on one or two of an individual's sex chromosome. Whereas Non-Sex-Related Inheritance is carried on the other thirty chromosomes that the individual also carries.

Sex-Related inherited genes that are passed via the father to male offsprings, carried on the Y chromosome, are easiest to spot in a family. All males will have this trait and no females will.

Non-sex-related inheritance can be passed from male to female and from female to male, this is sometimes harder to differentiate from genes carried on the X chromosome because the mother always gives an X chromosome.

Vocabulary:

phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

According to the National Institute of Health, different diseases can block the bile ducts and cause a problem with the flow of

Maurinko [17]

Blocked bile ducts would adversely affect digestion because it mostly passes through the digestive system. Bile is an important part of the body that is secreted by the liver to help the body digest fats. The bile ducts carry bile from the liver and gallbladder towards the pancreas and towards the duodenum, which is a part of the small intestine.
