Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
After crossing over of peonies, one with purple flowers and long stems, and the other with white flowers and short stems we will get the number of offspring 83 with purple flowers and short stems; 29 with purple flowers and long stems; 26 with white flowers and short stems; and 9 with white flowers and long stems.
A dominant allele is one that nullifies the effects of a recessive allele. The allele that is covered up by the dominant allele is known as a recessive allele.
This shows that a plant with purple flowers and long stems is carrying a dominant allele that masks the effect of the recessive allele in a plant with white flowers and short stems.
