When the comb jelly, Mnemiopsis leidyi, was introduced into the Black Sea, its population exploded to 500 comb jellies per cubic
nikitadnepr [17]

The answer is invasive species.


Invasive species are species that are not native to specific ecosystem, but they have a capability to spread widely through the ecosystem, This way they can threaten native species of the ecosystem or cause environmental harm. 

<span>After being introduced into the Black Sea, they greatly affect local ecosystem. In the new area, they have no natural predators and are able to spread. If they spread beyond the area they are introduced, they become invasive species which can overgrow native biotopes and are a great threat to the local biodiversity. This could lead to the extinction of some native species.</span>

Explain in detail how to decide the number of replications in a simulation study. Use fixed-sample-size and sequential procedure
erik [133]

Explanation:

Fixed sample size:

In this fixed sample size the data is studied and checked in order to find a relationship. The benefits it is easy to produce, and with it less reliable outcomes can be given.

Sequential procedures:

→Sequential procedures helps while we are collecting the data.

→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.

→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.

→In this two or more blocks of different sizes are prepared for testing.

→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.

Two independently segregating genes determine kernel color in wheat. Red color results from at least one dominant allele in both
Lera25 [3.4K]

Answer:

a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.

b) The expected phenotypic classes in the F2 are: 9:3:3:1

   9/16 R-B-, 3/16 rrB-, 3/16 R-bb,  1/16 rrbb

   Proportions 9:6:1.

9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)    

Explanation:

<u>Available data:</u>

  • red kernel: R-B-
  • brown kernel: R-bb or rrB-
  • white kernel: rrbb

1º Cross)  RRBB      x      rrbb

F1)             100% RrBb (red kernels)

2ºCross)   RrBb       x       RrBb

Gametes)  RB                   RB

                  Rb                   Rb

                  rB                    rB

                  rb                    rb

Punnet Square)      RB           Rb         rB         rb

                 RB      RRBB      RRBb     RrBB     RrBb

                 Rb      RRBb      RRbb     RrBB     Rrbb

                 rB       RrBB       RrBb      rrBB      rrBb

                 rb       RrBb       Rrbb       rrBb     rrbb

F2)  Phenotypic classes:

       <em>9/16 R-B-</em>

<em>        3/16 rrB-</em>

<em>        3/16 R-bb</em>

<em>        1/16 rrbb</em>

      Phenotypic proportions:

      <em>9/16 Red kernel (R-B-)</em>

<em>       6/16 Brown kernel (rrB- + R-bb)</em>

<em>       1/16 White kernel (rrbb)         </em>
