It is virtually impossible to locate the genetic factors involved in most psychological characteristics because of <u>polygenic inheritance</u>.
Multiple genes, or polygenes, generate features in polygenic inheritance. Numerous diverse phenotypes, or displayed qualities, may be expressed through polygenic traits. When phenotypes were expressed, a variety of inherited qualities are mixed together due to polygenic inheritance, a kind of incomplete dominant inheritance.
The phenotypic, such as the color of one's hair or skin, is produced by polygenes working together. Polygenic traits don't inherit in the same ways as Mendelian traits do. Multifactorial traits will be many polygenic qualities that have been additionally influenced through the environment.

Answer:
meiosis 1, anaphase
Explanation:
Meiosis is a type of cell division that consists of two rounds of cell division known as Meiosis I and Meiosis II, and one round of DNA replication, thereby the resulting cells (gametes) contain half of the genetic material found in somatic (body) cells. Both Meiosis I and Meiosis II can be divided into the following phases: Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. Alleles of a gene separate during the anaphase of Meiosis I (i.e., Anaphase I), because homologous chromosome pairs separate during this phase of the cell cycle.
Answer:
Scientists believe the counterclockwise rotation of the planets is caused by the way they formed in the debris field. Each planet may tilt at an angle from the direct north/south pole, causing seasons to occur. The planetary tilting does not change the basic nature of the planet rotation.
