Answer:
P generation: 1 purple flower (AA) : 1 white flower (aa)
F1 generation: 4 purple flowers (Aa) : 0 white flowers
F2 generation: 3 purple flowers (AA, Aa) : 1 white flower
Explanation:
Assuming the parents are AA and aa, the allele for white flowers is recessive, so there needs to be two of them for the trait to be expressed. Thus, the capital A purple allele that the other parent contributes will mask that white allele and all the flowers will appear purple. However, all of the offspring are Aa now, so when they are crossed, there's a 25% chance that they'll both contribute the lowercase a allele that codes for white flowers. Remember that if both of them give the lowercase a allele then the offspring will be aa and appear white.
Some living things are, protists, plants, animals, fungus, and bacteria
Non living things; Water, minerals, air, light, and soil.
It has increased chemical reactivity and it is primed to do cellular work.
Answer: It is a nonselective process, so it might cause an allele to disappear from the gene pool by chance brainliest?
Explanation:
Answer:
Positive Regulation of the Cell Cycle
Two groups of proteins, called cyclins and cyclin-dependent kinases are responsible for the progress of the cell through the various checkpoints.
