Food webs with fewer species are more sensitive to the loss of species and ecosystem disturbances

Species selection. Species selection is the process by which intrinsic biological characteristics in organisms change depending on the type of environment they're interacting with. In this case, the subsequent generations of the fly lost the ability to fly because their environment didn't require them to use wings for survival, hence they stopped growing them and subsequently lost the ability to fly.

The correct answer is explained below:</h2>
Explanation:
- According to the question, free ear lobes are dominant over attached ear lobes.
- Let the allele for free ear lobes be represented by F.
- Let the allele for attached ear lobes be represented by f.
- The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
- The gamete produced by the woman is: f.
- The genotype of the heterozygous man (father) with free earlobes is: Ff.
- The gametes produced by the man are: F and f.
- Mating the man with the woman we get the following offspring,
F f
f Ff ff
Phenotype Free ear lobe Attached ear lobe
- The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
- The probability that the parents would produce children with attached ear lobes is =
