Answer:

The correct answer is - autosomal codominant inheritance (due to multiple alleles).

Explanation:

Autosomal codominant inheritance or codominance is a pattern of inheritance where the alleles present of an autosomal gene express their character in the phenotype. In other words, in this type of pattern, no allele would be masked by other alleles and both will be expressed in the phenotype.

The human ABO blood group is an example of this pattern as there are three alleles A, B, and O. In the heterozygous case of AB blood group both A, and B alleles expressed together however, O is masked by both alleles A, and O.

Neurospora is an ideal organism to study the effects of genetic mutations because of several reasons. What is one of these
yawa3891 [41]

Answer:

Due simple growth.

Explanation:

Neurospora is an ideal organism to study the effects of genetic mutations because it is easier to growth and are simple. Neurospora crassa is used as a model organism because it has a haploid life cycle and easier to grow that makes genetic analysis simple. Analysis of genetic recombination is facilitated by the ordered arrangement of the products of meiosis in Neurospora ascospores so due to simple growth and haploid life cycle we can considered   Neurospora is an ideal organism.

Which of the following resources can be in limited supply in an ecosystem?
ivanzaharov [21]

Answer:

Food, sunlight, water, oxygen and shelter :3

Explanation:

As a growing population reaches the limits of the available resources in an environment, its size levels off to "match" the amount of resources available. In doing so, the population reaches its carrying capacity.

Another factor that affects the carrying capacity of an ecosystem is the rate at which decomposers can break down the remains of dead organisms within the ecosystem. The faster an ecosystem can recycle the nutrients in dead organic matter, the larger the populations it sustains can become.
