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.

In a certain forest, elephants and deer were feeding on certain types of plants. This plant community was larger than the elepha
Anvisha [2.4K]
The disappearance of the deer from the forest indicates the EXTINCTION OF THE DEER.
The extinction of the deer from the forest will throw the ecosystem out of balance and has negative impacts on the ecosystem. After all the deer has been eliminated, the elephants too will either have to find another source of  food or be wiped out.
