Question

Please help im really lost on this..

What kinds of mistakes in meiosis could produce an individualwith chromosomal trisomy?

1. Meiois 1 only
2. Meiosis 2 only
3. Meiosis 1 and 2
4. Neither of these could produce chromosomal trisomies

What would be the effect of a mutationthat prevented the function of meiosis-specific cohesins inmeiosis?

a.Would egg production or function be affected? Pleaseexplain

b.Would sperm production orfunction be affected? Please explain.

c.Whatif the mutation made the cohesins too stable, so they could not bereleased properly when sister chromatids separate in meiosisII?

Use diagrams to run through the stepsin meiosis, but this time please make the following types oferrors. Summarize the effect on the meiotic products for eachsituation.

a.In Meiosis I, both sets of homologous chromosomes for themedium chromosome segregate to the same pole.

b.In Meiosis I, one set of sister chromatids (medium) separatesprematurely, so that each segregates to opposite poles.

c.In Meiosis II, a set of sisterchromatids (medium) separates prematurely and both segregate to thesame pole.
