Euploid changes occur by which of the following developmental errors. A. Non-disjunction during Anaphase I of meiosis. B. Non disjunction during Anaphase II of meiosis. C. Failure of cell division and production of unreduced gametes during meiosis. D. Somatic doubling in the meristem leading to reproductive organs. E. Both A and B are correct. F. Both C and D are correct. G. All the answers are correct.

A. Non-disjunction during Anaphase I of meiosis.

Explanation:

Euploidy is an alteration in the organism´s natural number of chromosomes. Individuals with euploidy express a different number of homologous chromosomes set than the one from the normal number.

The cause of this alteration is that homologous chromosomes do not separate during the anaphase of meiosis 1.

There are two types of euploidy:

it is either c or d and i know for sure it is not a or b

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
