Answer:
a.The phenotypic proportions obtained after having the genotypes are 50% marbled seeds, 25% spotted and dotted seeds since they are codominant, 25% spotted seeds.
b. Taking into account the F1 genotypes in the previous point, the expected phenotypes for the first crossing are 100% marbled seeds and for the second crossing 100% dotted seeds.
Explanation:
Let's suppose:
Marbled allele: M
Spotted allele: S
Dotted allele: D
Allele for Clear: C
a. Because both crosses were between homozygous parents, the entire F1 genotype is the same.
For the first crossing the descendants have the MS genotype, and for the second crossing the descendants have the DC genotype. It is enough to make a Punnett square to obtain the different combinations of genotypes between the crossing of MS and DC.
Energy is vital for living organisms is our fuel . if there is no energy formed we can t talk about life because things cells that are too little to experience things have this purpose to form energy in order for us to function.we need to see the human body in a constant dynamic because every second is breaking and forming Atp( the primary source of energy) and using that atp for everything moving thinking keeping us healthy ex transporting macromolecular substances like glucose that is lately broke down (glicolisis) and forms other molecules of AtP .And the cycle goes on.In my opinion is decisive because if there is no energy there is no life the other things could work if the the everyday light goes away the moon can still be there we can still be there but at some point we will dissapear.Energy is requiered for everything to occur it repairs builds and maintains body tissues without it the has no chance to survive .Because there will be no metabolic processes and no cycle of energy exchanges.
The given example suggests the principle of resource partitioning.
The resource partitioning is a method of division of resources present in a particular niche to avoid the competition. In this case, the organism divide the regions having the abundant resources and they do not interfere in each others region.
In this case, the resource partition takes place by dividing the regions in the flask. one species use he resources present in the middle region and other uses the resource in the bottom.
