Cross a pure A type blood with a pure B type blood;write the phenotype, genotype, and ratios

Biology

Irina18 [472]3 years ago
8 0
If one parent has the pure A blood type (both alleles are A) is with genotype AA The other parent has the pure B blood type (both alleles are B) is with genotype BB
 Crossing these two: AB AB AB AB
<span>which means that all of the children will have AB blood type (phenotype). This happens because of the codominance. The A and B alleles are codominant and therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB.</span>

Discuss possible disturbances and their cause in an ecosystem​
KonstantinChe [14]
In ecology, a disturbance is a temporary change in environmental conditions that causes a pronounced change in an ecosystem.
Disturbances often act quickly and with great effect, to alter the physical structure or arrangement of biotic and abiotic elements.
Disturbance can also occur over a long period of time and can impact the biodiversity within an ecosystem.
Major ecological disturbances may include fires, flooding, storms, insect outbreaks and trampling.
Earthquakes, various types of volcanic eruptions, tsunami, firestorms, impact events, climate change, and the devastating effects of human impact on the environment (anthropogenic disturbances) such as clearcutting, forest clearing and the introduction of invasive species can be considered major disturbances.
Not only invasive species can have a profound effect on an ecosystem, but also naturally occurring species can cause disturbance by their behavior.
Disturbance forces can have profound immediate effects on ecosystems and can, accordingly, greatly alter the natural community. Because of these and the impacts on populations, disturbance determines the future shifts in dominance, various species successively becoming dominant as their life history characteristics, and associated life-forms, are exhibited over time.
