The correct answer is: a. n+1, n+1, n-1, n-1
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during mitosis or meiosis. There are three forms of nondisjunction:
1. failure of a pair of homologous chromosomes to separate in meiosis I ,
2. failure of sister chromatids to separate during meiosis II, and
3. failure of sister chromatids to separate during mitosis.
As a consequence of nondisjunction abnormal chromosome numbers appears. If nondisjunction occurs during the meiosis I (anaphase I), this means that at least one pair of homologous chromosomes did not separate. The consequence is two cells that have an extra copy of one chromosome and two cells that lack that chromosome.
B. defiantly b. because it can survive in most climates.

- <em>Grasses dominate is a temperate grasslands</em>
- Trees and large shrubs are almost found in <em>grassland zones</em>
- There are numerous types of grasses that live in this biome purple <em>needlegrass, wild oats, foxtail, ryegrass, and buffalo grass </em>
- Grasslands are known by various names in various parts of the World such as <em>'Steppes' in Asia; 'Prairies' in North America; 'Pampas', 'Llanos' and 'Cerrados' in South America</em>
