If a father is affected by an X-linked dominant condition and the mother is not, which children can inherit the condition?

Biology
1 answer:
kaheart [24]3 years ago

Answer:

only females

Explanation:

In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.

Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).

N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.

Compare renewable and nonrenewable resources, and discuss the effects of each on biodiversity.
Andrei [34K]

Answer:

Renewable resources cannot disappear, non-renewables will not last forever. Non-renewable energy sources, such as coal, nuclear power, oil, and natural gas, are available in limited quantities.

Explanation:

A renewable resource, for example, is solar energy. It is renewable because the sun can never disappear.

Non-renewable resources take a long time to replenish, if this ever happens. Renewable resources naturally recharge over a relatively short period. Non-renewable resources are natural resources that exist in fixed quantities and can be utilized. Examples include fossil fuels such as oil, coal and natural gas.

Both types of resources have a big influence on biodiversity and people shouldn't be spending them without limit.

What is the electrical pathway of the heart, in order? NOTE- this includes pacemaker and conduction components.
s2008m [1.1K]

Answer:

The correct answer will be option A.

Explanation:

The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.  

This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.

Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.

Thus, option-A is the correct answer.
