Sexual selection is a type of natural selection resulting from variation in the ability to obtain mates.
The genotype is the genetic makeup on the other hand phenotype is the outcome or expression of that particular genotype.
genotype is an organisms genetic makeup
genotype
Simple ones will try, but it is a waste of much energy. Thus behaviors were selected for to only mate efficiently. i.e. only with you own genotype.
Genotype
Although organisms with the same physical characteristics have the same PHENOTYPE, they might have different GENOTYPE, or genetic makeup.
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
For the case of the human, an individual with XX genotype is female. Other organisms have different ways of determining sex.
Phenotype
Genotype
No, genotype actually determines phenotype.
Fold line are organisms that produce offsprings of different GENOTYPE from their parents and differ among them. They contribute to SPECIES DIVERSITY.
