Determine the effect of average height of males and females and whether their mean heights are more or less the same
BIOLOGY – GENETICS LAB:
AIM: To determine the effect of average height of males and females and whether their mean heights are more or less the same, as investigated in the Grade 11 IB students at Indus International School.
BACKGROUND INFORMATION: Average height for men and women within a population varies a lot, and men, 9 times out of 10 taller than women. Majority of females reach terminalheight at a younger age than males, as puberty happens first in girls.A person's height is decided by genetic causes, research shows that height is but an inherited trait. Parents may worry that a short child is a consequence of an intrinsic health problem in the child; doctors now are able to crunch DNA trends as a fairly accurate predictor of height. The gender of the child also factors. For most peoples in the world, adult males on average tend to be taller than adult females. For males mother’s height is added to father, plus 5 inches, the sum is then divided by two. For females, mother’s is added to father’s, again calculated in inches, but five inches are subtracted from the total, divided by two. This is a predictor of a child's height in adulthood, save a few inches. Family members are likely to be of similar stature. Testosterone is another reason why boys are taller than girls, as it gives males extra HGH. Diet is yet another facet of height or the lack of it.
