Can someone describe natural selection for me?

Biology
1 answer:
MAXImum [283]3 years ago
6 0

Answer:

This is a process whereby the better 'fitted' or adapted varieties of species in populations are selected by environmental pressures. This affects the survival and reproduction of the individuals in the plant/ organism populations in such a way that eventually a variety better adapted to the drier climate dominated the population.

Natural selection is a never-ending process in nature since some environmental factor keeps on changing all he time.

Now, suppose that the three tomato genes from Part A did not assort independently, but instead were linked to one another on the
Ksenya-84 [330]

Answer:

All eight phenotypes are possible but parental phenotypes will be more in number

Explanation:

In the cross MmDdPp X mmddpp eight types of offspring are possible because MmDdPp will produce eight types of gametes. These offspring are:

  • MDP/mdp
  • Mdp/mdp
  • mDp/mdp
  • mdP/mdp
  • MDp/mdp
  • mDP/mdp
  • MdP/mdp
  • mdp/mdd

In absence of linkage, the genes would have assorted independently producing all the eight types of offspring in equal number. Hence the phenotype ratio would be 1:1:1:1:1:1:1:1.

If the genes are linked they will show the tendency to get inherited together and crossing over will not take place up to the expected degree. Hence fewer recombinants will be produced and more parental type offspring will be produced.

Which organelle in a prokaryotic cell contains genetic information? Question 3 options: Capsule Ribosomes Flagellum Nucleoid.
Snowcat [4.5K]

The single-cell organism that does not contain a well-defined nucleus and membrane are called prokaryotes. The genetic information is contained in the nucleoid of the cell.

<h3>What is a nucleoid?</h3>

Nucleoid is a region in the cytoplasm of the prokaryotic cell that is an irregular-shaped structure that consists of the genetic material of the cell.

The process of the replication and transcription of the DNA and RNA of the prokaryotic cell occurs here and is different from the eukaryotic nucleus by lacking a nuclear membrane.

Therefore, prokaryotic genetic material is contained in the option D. nucleoid of the cell.
