Apoptosis is programmed cell death. The body is this to get rid of unneeded or abnormal. The body will get rid of cells with damaged DNA before they can become cancerous.
Mendel studied a total of seven traits of garden peas. His experiments were successful because the pairs of factors for the traits he studied were on seed shape<span>, flower </span>color<span>, </span>seed coat tint<span>, </span>pod shape<span>, unripe </span>pod color<span>, flower location, and plant height</span>
A duplicated chromosome remains tightly paired with its partner at a region called the Centromere
Answer:
humans are adapted to a wide range of environments, and genetic variation leads to phenotypic variation
Explanation:
It has been shown that the average genetic variation between human individuals is about 0.1% (i.e., one base pair out of every 1,0000 are different between any two individuals). This value seems low, but it is huge when we consider that the current estimate for the world population is 7,800,000,000 people. The phenotype is the result of the interaction between genotype and environment. Genetic variation is the raw material that enables some individuals to adapt to different environments. As species, humans have a high genetic diversity in order to develop a wide range of phenotypes well adapted to different environmental conditions.
