For example, if someone has contributed $10,000 post-tax and $30,000 pre-tax to a traditional IRA and wants to convert the post tax $10,000 into a Roth, the pro-rated amount (ratio of taxable contributions to total contributions) is taxable.or example, if someone has contributed $10,000 post-tax and $30,000 pre-tax to a traditional IRA and wants to convert the post tax $10,000 into a Roth, the pro-rated amount (ratio of taxable contributions to total contributions) is taxable.
A trisomy and a monosomy are types of numerical chromosome abnormalities that can cause certain birth defects. Normally, people are born with 23 chromosome pairs, or 46 chromosomes, in each cell â one inherited from the mother and one from the father.
Trisomy. If a diploid cell undergoes meiosis and produces two gametes that are normal, and one with nâ 1 chromosomes, and one with n + 1 chromosomes, what type of error occurred? A nondisjunction error occurred in meiosis II, in which both sister chromatids of a chromosome migrated to the same pole of the cell.f a diploid cell undergoes meiosis and produces two gametes with n + 1 chromosomes and two gametes with nâ 1 chromosomes, what type of error occurred? A nondisjunction error occurred in meiosis I, in which both members of a homologous pair migrated to the same pole of the cell.
