Some key reasons for partially developed offspring:
• Genetic issues, parents sexual organs incorrectly formed, in turn malforming the offspring
• Pollution, parents consuming something they shouldn't have while the offspring was developing
• Breeding between relations; accidently mating with a brother or sister, in turn causing defects as many of the genes are the same
The answer here is "False" when the Tracheostomy is no longer needed, it is allowed to close or heal. They are for your throat when the airway is obstructed or blocked in some way. So no they are not permanent.
The correct answer is: b) directional selection
Directional selection is a type of natural selection in which an extreme phenotype is favored over other phenotypes. In this case, phenotype of large crickets will be favored, because they cannot be eaten by lizards. Large crickets are advantageous in surviving and reproduction. This will cause the allele frequency to shift over time in the direction of that large size phenotype.
