Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.

Systolic blood pressure:_____________ a) is the higher number of a blood pressure reading. b) is the lower number of a blood pre

Alik [6]

Answer:

is the higher number of a blood pressure reading.

Explanation: systolic blood pressure is the higher number of a blood pressure reading and its measure in millimeter of mercury.

Systolic pressure is the amount of pressure in the arteries when contraction takes place in heart. Diastolic pressure is the pressure the heart when it relaxes. It is the lower number of blood pressure reading

When the systolic pressure is >120mm Hg and diastolic is less than 80mm Hg it is normal

120-129mm Hg and diastolic less than 80mm Hg it high and such person needs a regular medical check up

But when systolic 129-139 mmHg

and diastolic is 90mm Hg or above it means the individual is having hypertension stage 1

Above 140mm Hg is hypertension stage 2 and it is the most severe stage. It means the person is hypertensive and medical attention needs to be seek for necessary treatment as this could lead to death of such individual if not well managed.
