When Mendel crossed two hybrid plants for stem height (Tt), what results did he always get?

Biology

Ivahew [28]4 years ago

When you cross two hybrids, the results always come in a 3:1 ratio as follows:

3 is the inheritance of at least 1 dominant allele
1 is the inheritance of two recessive alleles

Punnet Squares are very useful!
     <u>T     t  </u>
T | TT | Tt |
t  |<u> Tt | tt  </u>|

Three out of 4 boxes have offspring that express the dominant trait (tall plants) and 1 out of 4 boxes expresses only the recessive trait (short plants).

Hope this helps! :)

During upwelling, nutrient-rich water rises to the surface. How would this most likely affect the biotic components of the ecosy
romanna [79]

Answer:

Explanation:

The upwelling of nutrients rich water to the top will increase species numbers and diversity.

When a particular area has the ability to sustain live by providing food and nutrients required for growth of organism the population will greatly increase this is because nutrients is the major source of competition among species for survival and every species goes in search for it and where there is abundance of it there will be a rise in population and diversity.

Varying type of species that are diverse in nature comes together, mating occurs more diverse species are formed.

Diffusion is important for living organisms because ..
Mrrafil [7]
This simple concept describes the process by which cells exchange toxic gases for life-sustaining gases. It also describes how nerve cells are able to send electrical signals to each other cells. Diffusion tells embryonic cells where to crawl and when they have arrived. Diffusion also makes it possible to reduce the loss of body heat to the surrounding environment.
