If a diploid cell undergoes meiosis and produces two gametes that are normal, and one with n − 1 chromosomes, and one with n + 1 chromosomes, what type of error occurred?

Nondisjunction in meiosis II

Explanation:

Nondisjunction is the condition which occurs during the cell division stages in which the homologous pair of chromosomes or the sister chromatids fails to separate during the anaphase in meiosis.

When nondisjunction occurs during anaphase I of meiosis it results in the two cells with monosomy (n-1) and two cells with trisomy (n+1) whereas when nondisjunction occurs during meiosis II, then it results in the formation of two normal cells, one with monosomy (n-1) and one with trisomy (n+1).

In the given question, since the two normal, one n-1 and one n+1 condition are present therefore the nondisjunction occurs in meiosis II.

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
