How does the possible impact of a chromosomal mutation that occurs?
Papessa [141]
  If the mutation occurs during meiosis, the mutation will be incorporated into a gamete. If that gamete is the one that eventually fuses with another gamete (i.e. if it's the sperm that fertilizes the egg), that mutation will be passed on to the offspring. As all the offspring's cells are the result of the first two gametes, all the organism's cells will have that mutation. Obviously this can have dire consequences for the offspring, if the mutation is harmful.

erastovalidia [21]

Answer:

Explanation:

Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.

During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.

Steps involved in double fertilization are:

1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.

2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.

3) After the completion of double fertilization, a fruit and seed develop.
