Question involving the equations for Hardy Weinberg equilibrium (A^2+2Aa+a^2=1, A+a=1)
Alinara [238K]

Answer:

Frequency of dominant allele is 0.9029

Explanation:

Total number of organisms = 12,845

Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.

Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249

Frequency of recessive allele (q) = 1249/12845 = 0.0971

Frequency of dominant allele (p) = 1- q = 1-  0.0971 = 0.9029

Failure in a particular structure of the heart tends to cause a backup of blood in the lungs, known as pulmonary congestive hear
xeze [42]

Answer:

Left ventricle.

Explanation:

Human heart is divided into four chambers - two auricles and two ventricles. Heart acts as the pumping organ and carries both oxygenated and deoxygenated blood in the right and left ventricles.

The failure of functioning of any chamber of heart may cause a particular disease in the individuals. The pulmonary congestive heart failure occurs due to the failure of the left ventricles of the heart. The left ventricle carries blood from heart to the body tissues, its failure leads to the backup of blood in the lungs.

Thus, the answer is left ventricle.
