The f1 generation may have genes for short plants just that the genes for long plants are dominant over the genes for short plants(recessive) so when cross pollination happen and that two f1 long plants which are homozygous cross pollinate, the recessive genes have a chance of being paired up in new offspring(F2 offspring) thus the possiblity of short plants in f2 generation

For example, the cross between two pure plants (homozygous), being a dominant characteristic over another, in case high on short.

High = AA
Short = aa

F1 = AA x aa = 100% Aa = high = heterozygous

F2 = Aa x Aa
 
      A    a
A  AA  Aa
a  Aa  aa

Therefore, of this crossing, we have
75% High plants (AA e Aa)
25% short plants (aa)

This is possible because the heterozygote plant had the short plant allele.

One of the disadvantages of experimental research is that __________.
timurjin [86]

The correct answer is: b. it doesn’t often reflect reality.

While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: <em>lack of ecological validity</em>.

Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
