Consider the abbreviated model of meiosis. the end result of meiosis should be the production of four haploid gametes. in this example, an error has taken place. describe and name this error.
a)nondisjunction of sister chromatids during meiosis ii. sister chromatids fail to separate.
b)translocation of sister chromatids during meiosis ii. one chromatid is translocated into incorrect cell.
c)separation mutation during meiosis i. resulting gametes in meiosis ii have incorrect chromosome number at end of meiosis.
d)replication error during meiosis i. results of mutation show during meiosis ii as incorrect chromosome number in two gametes.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
