Explanation:
Answer:
Mitosis results in two identical daughter cells, whereas meiosis results in four sez cells so yeah
Recessive traits often seem to disappear because two recessive alleles are needed to produce the recessive phenotype. They can skip a generation and then reappear if an individual inherits two copies of the recessive gene. Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations.
Recessive traits disappear because recessive alleles can hide out in heterozygotes, allowing them to persist in gene pools and natural selection can only see the phenotype, not the genotype. While harmful recessive alleles will be selected against and it's almost impossible for recessive alleles to completely disappear from a gene pool.

Ecologists are the persons who study the interrelationships between organisms and their environments. Like they research upon the species found in forests or deserts interact with each other and as well as their surroundings.
They test whether a species is occupying its complete fundamental niche or only a portion of it by observing if the species are expanding their range after the removal of a competitor because two species with the same fundamental niche will exclude other competing species.
