When heterozygous advantage exists, the fitness of the heterozygous genotype has higher fitness than either homozygote.
<h3>What are genotypes and phenotypes ?</h3>
A person's genotype is made up of all the alleles they have for a certain gene. The sum of a person's attributes or observable characteristics is their phenotype. The phenotype of an organism is only impacted by its genotype, which is directly inherited from its parents.
<h3>Types of genotype :</h3>
There are three different genotype types: homozygous dominant (PP), homozygous recessive (PP), and heterozygous (Pp). The traits are the same in homozygous dominant and heterozygous genotypes.
<h3>
Heterozygous</h3>
The existence of two unique alleles at a specific gene locus. One normal allele, one mutant allele, or two separate mutant alleles may be present in a heterozygous genotype.
<h3>Homozygous </h3>
Contrary to a heterozygous genotype, a homozygous genotype exists. You inherited two copies of the same allele if you have a gene called homozygosity. In other words, both of your biological parents contributed the same variations.

Answer:
1. A. Different genotype
2. B. 50%
Explanation:
the meaning of heterozygous Is Different genotype.
50% of offspring would be recessive when crossing two hybrid parents
As the intense competition of the species are observed in clumped distribution, so the answer is distribution of individuals will tend to be clumped.
<h3>
What is intraspecies competition?</h3>
The competition which occurs between individuals of the same species based on common need for a limited resources, leading to a reduction in the survival and reproduction rate.
Intraspecific competition for exploitation which is an indirect type observed when an individual consumes the available resources.
Intraspecific competition by interference observed when the individuals fight to access for other's food.
Hence, answer is clumped.

Answer: Option E (B and D are the only examples.
Mediterranean ecosystem with hot dry summer and fire can be found on various continents across the globe. Plants in these ecosystem have evolve similar adaptations to survive these circumstances.
Echidnas are egg laying mammals that live in Australia and new Guinea. They are sometimes known as spiny anteaters since they are covered in spines and mostly eat ants and termites. As such they resemble south American anteaters and hedgehogs but are not closely related to them. Instead echidnas descended from an aquatic platypus like ancestor.
Explanation:
Divergent evolution is a process where different organisms with different anscetors evolve independently and develop similar traits due to their adaptation to similar environment.
Another example is the similarities between hummingbird and hummingbird moth, the evolved from different ancestors and yet posses similar characteristics.
T<span>he nurse should assess the patient's prior knowledge and his ability to participate in any education sessions. The nurse should explain to the patient the possible outcomes of each medication. The patient should also be well instructed of the symptoms and other reactions brought about by medication.</span>
