Biology

Answer:

Ecological competition occurs when living organisms, including animals, plants, bacteria and fungi, need the same limited resources to thrive in their shared environment. An ecosystem could collapse if several species needed the same scarce resources to complete their life cycle. Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.

Distinguish between directional, stabilizing, and disruptive selection. Give examples.
pashok25 [27]
Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.

Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.

Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of ​London's peppered moths.

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if both dogs are heterozygous (Ll)
Brut [27]

Answer:

75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.

Explanation:

After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.

If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.

This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.

I hope this was helpful! Let me know if you need any clarity.
