Legend has it that there was a less famous geneticist in the 1800s
NNADVOKAT [17]

Answer:

Few crosses

The complexity of cat genetics

Crosses not controlled by the researcher

Explanation:

The purpose of this question is to determine why  Megor Grendel is less famous than that of Gregor Mendel.

Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:

  • The researcher has total control over the crosses.
  • Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
  • Pea plants may be examined for a greater series of generations than cats or other animals.
  • Because plant genetics is not overly complicated, several traits may be investigated at the same period.

As a result, the primary factors why Megor Grendel's experiments are not well-known:

  • The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
  • Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
  • Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.

As a result, it is impossible to draw any conclusions from them.

What is represented by the base root of a phylogenetic tree?
NeX [460]

The common ancestor.

A phylogenetic tree shows how a species originates (by evolution) other species. It’s very similar a genealogic tree. If you want your family tree, you should write down your name and the names of all your brothers and sisters and then draw a line from all those names to the names of your parents, and then draw a line from the name of your father to the names of your gramma and grampa, and then do the same with the names of your aunts and uncles. If you repeat the process with many, many generations, you will have the common ancestor to all of those relatives. You can do the same with species: for example, humans are supposed to have a common ancestor with monkeys, so their lines will end together in the same point in the graph. Then you have to draw a line from that point to another point that will be shared with other mammalians, then Mammalians share a point with other vertebrates, and so on… If you keep on going, you will get to LUCA someday.
