Non-Mendelian inheritance patterns can be sorted into three categories: incomplete dominance, codominance, and sex-linked traits
mart [117]

Answer: B (Color blindness)

Explanation:

Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.

About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.

The chart shows the advantages and the disadvantages of using DNA technology. Advantages Disadvantages Allergies Unknown effects
zepelin [54]

Answer:

The correct answer would be allergies.

Allergies is one of the common disadvantages of recombinant DNA technology.

It has been observed that use of genetically modified crops can cause life-threatening allergies.

The possible reason is that the introduction of new genes in the crops may lead to the formation of new proteins our body has never encountered with. These proteins may have a potential to cause allergies or any other life-threatening diseases or complications.

Which statement best describes a forest ecosystem that has not experienced any disturbances or natural disasters in the past 100
sveticcg [70]

Answer:

The given question is incomplete, as there is no options provided, and are not available anywhere. But in general, if a forest ecosystem has not experienced any kind of disturbances or natural disasters in the last 100 years then the various plants and animals species dwelling in that forest are reasonably stable.

Explanation:

A forest ecosystem is usually defined as a distinct ecosystem that is comprised of trees, plants and animals, and micro-organisms, in an area that interacts with the abiotic factors such as water, soil in order to survive.

If a forest ecosystem is not disturbed by any anthropogenic or natural disasters for the past 100 years, then the species living in this ecosystem becomes reasonably very stable. They will be adapting to the environment and habitat becomes permanent. There will not occur much physiological and morphological variation in these species.
