Answer:

<h3>A) Only Male offspring can inherit the disease. </h3>

Explanation:

As per the pedigree chart, only the males are shown as affected by the disease. Thus, it must be a sex-chromosomal inheritance, expressed in the Y chromosome or the male chromosome.  

As the females in the family are unaffected, hence the mother in the original parental generation cannot be a carrier.

It is likely that the father from the original parental generation might be the carrier.

As there are affected individuals in both the generation after the original parental generation ( the last generation having two more affected males), the statement that the chances of inheriting the decease with each successive generation is not true.

the allele for yellow peas is dominant to the allele for green peas. how would you represent the alleles of a plant that is hete
goldfiish [28.3K]

Answer: The alleles of a plant that is heterozygous for seed color can be represented as Y for dominant allele for yellow seed and y for recessive allele for green seed.

Explanation: A plant that is heterozygous for seed colour has one dominant allele and one recessive allele for seed colour. If Y represents the dominant allele for yellow seed colour and y represents the recessive allele for green seed colour, therefore the plant has a genotype of Yy. A dominant allele is one that has the ability to mask the effect of a recessive allele while a recessive allele is one whose effect is masked by a dominant allele. Dominant alleles are denoted with upper cases while recessive alleles are denoted with lower cases. A plant that is heterozygous for seed colour with genotype Yy will manifest outwardly as Yellow seed colour due to the presence of the dominant allele Y.

The nurse is assigned to watch the cardiac monitors in the constant care unit and notes four different clients displaying arrhyt
Tresset [83]
<span>The nurse should give the highest priority care to the Ventricular Arrhythmias Patient. Because Ventricular arrhythmias start in the heart's lower chambers, the ventricles. They can be very dangerous and usually require medical care right away. Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Ventricular tachycardia is an abnormal electrical impulses that start in the ventricles and cause an abnormally fast heartbeat. This often happens if the heart has a scar from a previous heart attack. Usually, the ventricle will contract more than 200 times a minute. Ventricular fibrillation is an irregular heart rhythm consisting of very rapid, uncoordinated fluttering contractions of the ventricles.The ventricles do not pump blood properly, they simply quiver. Ventricular fibrillation is life threatening and usually associated with heart disease. It is often triggered by a heart attack.</span>
