Mutations may be silent, meaning they don't affect an organism, but are still there. Also, some mutations occur in somatic cells and therefore can't be passed on to species, which means they won't affect evolution.
The mechanism of evolution that has been exhibited here is known as bottleneck effect. The fact that a sudden incident of the tree falling caused the death of rare alleles and this resulted in the decrease in genetic diversity of the population. I hope that this is the answer you were looking for and it has helped you.
Tonic-clinic seizures are known as ictal events
Simply place a 2 above each ...... gene pair and a one above each .... gene pair. Then multiply the numbers together to obtain the total number of different possible gametes.

Answer: Angiosperms are the plants which produce flowers for sexual reproduction.
Explanation:
In the angiosperm life cycle the following events occur:
1. Seed germination: Under suitable condition inside the soil obtain water, oxygen and minerals the seed germinates and from the two precursors plumule from where the stem emerge and radicle from where the root emerges.
2. Mature plant with flower: The plant gets matured with the develop of root and shoot and from the shoot the bud originates which produces the flower.
3. Pollination: During the process of pollination a mature pollen grain is transferred towards the female reproductive structure typically the stigma receives the pollen grain.
3. Fertilization of pollen with egg in ovary: The pollen is the male gametophyte which develops in the anthers which are the male reproductive structure of the flower and the egg or ovule is the female gamete which develops inside the ovary or female gametophyte. The fusion of male gametes provided by the pollen grain with that of the ovule is called as fertilization.
4. Formation of fruit with seed: After the fertilization process the ovules develop into seed and the ovary into fruit.
5. Seed dispersal: The fruit gets detached from the plant and it may get rotten and dried the dried seeds disperse and may germinate in favorable conditions.
