What is the problem with inbreeding

Biology
1 answer:
Mrrafil [7]3 years ago
8 0

Answer:

It reduces genetic diversity and increases the proportion of deleterious recessive alleles

Explanation:

Inbreeding occurs when two genetically-related organisms mate and produce offspring. The breeding of genetically close individuals results in a loss of genetic variation in the population, as there is less "mixing" of different alleles to produce heterozygous (possess 2 different alleles) individuals.

This means that there is an increased chance that any deleterious alleles will become expressed (as there is less variation and more likely that homozygous individuals exist). These can be deleterious and potentially disease-causing. This reduces the fitness of the population.

Estimating Population Size – Review the two approaches to estimating population size and answer the following questions.
Andre45 [30]

Answer:

b) there are 56 deer in 1000 acres of area.

Explanation:

If a person has 1000 aces of land and a local wildlife biologist tell him that on every 18 acres only one deer is present so in 1000 acres there are 56 deer are present.

calculation;

1 deer ------ 18 acres

x --------- 1000 acres

by cross multiplication, we get

18 x = 1000

both side divided by 18, we get

x = 55.5

by rounding off we get

x = 56

Explain how goal of today’s classification system differs from earlier systems
gladu [14]

Classification systems previously were having very different goals than modern classification systems. If we look at old eras, scientists like Aristotle  and Theophrastus  tried to classify organisms on the basis of apparent characteristics, habitat and simple other traits.

Old classification systems had alot of errors and flaws. For example they classified fish and whale in one group because they lived in water, now we know fish is amphibian while whale is mammal.

So we can say that the goal o earlier classification system were just to make groups of organisms on the basis of External features.

Goal of modern classification system:

Modern classification approach was started by Linnaeus. It focuses more on biological delimitation and evolutionary histories than mere external characteristics. It organizes organisms in groups in such a way that grouping reflects their evolutionary relatedness. It is not just specie level but also focuses on sub-specie and population level classification.


Thus modern goal is better in many terms and is more reliable than old classification goals.


Hope it helps!

charle [14.2K]

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.
