Answer:
Segregation
Explanation:
The fact that each plant gets only one allele from each parent plant is detailed in the law of law of segregation. Mendel found that each pair of alleles segregates independently of the other pairs of alleles during gamete formation. When sperm and egg unite at fertilization, each contributes its allele, restoring the paired condition in the offspring. The allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.
Accurate measurement reduces parallax errors. one step that can be taken is ensuring that you measure from zero. This step applies to using instruments such as rulers or other devices for measuring length. Another step is to ensure that the instrument being used is calibrated. The next step is to use the appropriate device for the type of measurement.
