Fraternal twins, while conceived at the same time, are not genetically identical.

Biology
1 answer:
Volgvan2 years ago
7 0

Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.

Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.

Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.

During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.

Nikitich [7]

Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.
