Knowing that
purple flowers are dominant (have a higher percentage of passing certain information to offspring) and white a recessive (have a much lower chance of passing certain information to offspring) the plants of the

generation (first generation bread) will be all purple.
When a white-flowered pea reproduces with a purple-flowered pea all of the offspring will be purple.
When 2 offspring (purple-flowered) of the

generation breed, there is a 15% percent chance of offspring being white-flowered.

Hope it helped,
Happy homework/ study/ exam!
Answer:
The skin prevents pathogens from entering our body. It covers almost all parts of our bodies and if we get a cut, the skin will begin to heal itself so no bacteria can get into our bodies and cause infections.
Explanation:
The complementary DNA strand would be TAGCCATGT.
Answer: Probability/mutations
Explanation: A punnett square predicts the probability that a child or the offspring will receive specific genes or look a certain way. The genes with the highest percentage or usually the ones that show, but sometimes recessive genes are the ones that show through, which may be what you mean by a different genotype/phenotype being different that what was predicted by the punnett square.
a mutation may also occur that messes up all of this.
