1 answer:
Ecological models ( physical and computer) enables the Simulation of a large scale ecology which makes it easier to identify an ecological problem and also design a solution in relation to the problem identified.
An ecological model is the simulation of the ecosystem which is used for survey, in order to identify, ecological problems, reveal the properties of the ecology, and also for the testing of scientific hypothesis. which would have been difficult to be carried out on a real ecosystem.
Ecological models can be grouped into; biodemographic, bioenergetic, and biogeochemical. and they are applicable in wildlife conservation and agriculture.
Hence physical and computer ecological models can be used to design a solution for an ecological problem by the simulation of a large scale ecology to identify and design a solution

Here is the complete question
The seeds in bush bean pods are each the product of an independent fertilization event. Green seed color is dominant to white seed color in bush beans.
If a heterozygous plant with green seeds self-fertilizes, what is the probability that 6 seeds in a single pod of the progeny plant will consist of:
A) 4 green and 2 white seeds?
B) all white seeds?
C) at least 5 white seeds?
Answer:
A) 0.3
B) 0.0002
C) 0.001
Explanation:
Let the allele for Green plant be = P
Let the allele for white plant be = p
Let the heterozygous plant be Pp, if self fertilization occurs we have:
P p
P PP Pp
p Pp pp
From the punnet square above, we have the following cross;
PP, Pp, Pp, pp
Since P is dominant to p; we have a phenotypic ratio of 3:1 between the dominant phenotype ( PP, Pp, Pp ) and recessive phenotype ( pp )
NOW, the probability for the green plant(i.e PP or Pp) will be:
the probability for the white plant (pp) will be:
A)
what is the probability that 6 seeds in a single pod of the progeny plant will consist of 4 green and 2 white seeds?
=
The probability includes the use of permutation:
=
= 0.2966
≅ 0.3
B)
What is the probability that 6 seeds in a single pod of the progeny plant will consist of all white seeds?
Since probability for white seed =
The probability that 6 seeds will consist of all white seeds will be =
= 2.44 × 10⁻⁴
= 0.000244
≅ 0.0002
C)
What is the probability that 6 seeds in a single pod of the progeny plant will consist of at least 5 white seeds?
For at least 5 white seeds, the probability will consist of 5 white seeds and 6 white seeds.
For 5 white seeds; we have:
5 White and 1 Green Since there are 6 permutations.
The probability For 5 white seeds will therefore be :
= 7.32 × 10⁻⁴
= 0.000732
For 6 white seeds; we have:
Only one permutation for 6 whites since there will no be any presence of any green seed.
= 2.44 × 10⁻⁴
= 0.000244
∴
The total probability for at least 5 white seeds = 0.000732 + 0.000244
= 9.76 × 10⁻⁴
= 0.000976
≅ 0.001
