Best answer: What happens if nondisjunction occurs during meiosis 2?

Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II. Since meiosis I proceeded without error, 2 of the 4 daughter cells will have a normal complement of 23 chromosomes. The other 2 daughter cells will be aneuploid, one with n+1 and the other with n-1. What happens …

Question: Does meiosis produce diploid daughter cells?

Mitosis and meiosis are both types of cell division. Mitosis is the process by which most cells in the body divide, involves a single round of cell division, and produces two identical, diploid daughter cells. … Meiosis involves two rounds of cell division and produces four non-identical haploid daughter cells. What produces diploid daughter cells? …

Question: Are homologous chromosomes haploid or diploid?

Cells with homologous chromosomes are diploid. Reproductive cells, called gametes, are different. They contain only half the full number of chromosomes—one chromosome from each pair. These cells are haploid. Do homologous chromosomes produce haploid or diploid? Diploid organisms inherit one copy of each homologous chromosome from each parent; all together, they are considered a full …

Why do chromosomes double before mitosis?

Before mitosis starts, all the chromosomes in the nucleus replicate their DNA to make identical copies. The nucleus now contains two sets of replicated chromosomes, twice as many as a normal body cell. Why are chromosomes duplicated before mitosis? Before mitosis occurs, a cell’s DNA is replicated. This is necessary so that each daughter cell …

Are evidence based practices sufficient for educating students with autism?

To improve the outcomes of children with ASD, educators should implement evidence-based practices (EBPs), strategies that have been shown to be effective in teaching appropriate behaviors and skills and decreasing inappropriate behaviors for a given population. What is a reason to use evidence-based practices with students with autism? The interventions that researchers have shown to …

Is n the diploid number?

Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n). Retroviruses that contain two copies of their RNA genome in each viral particle are also said to be diploid. Is diploid 2n or N? Humans have 46 chromosomes in each diploid cell. … Among …
