The way in which new species can be formed by sympatric speciation . Concept introduction: Speciation is part of evolution where new species arise from existing species as a result of evolutionary mechanisms. Sympatric speciation is a type of speciation where new species evolve in the same geographical area of their ancestral species and both the newly evolved species and the ancestral species are in the same geographical location.

Summary Introduction

To explain: The way in which new species can be formed by sympatric speciation.

Concept introduction: Speciation is part of evolution where new species arise from existing species as a result of evolutionary mechanisms. Sympatric speciation is a type of speciation where new species evolve in the same geographical area of their ancestral species and both the newly evolved species and the ancestral species are in the same geographical location.

Summary Introduction

To explain: The reason why it is harder for speciation to occur in sympatry than in allopatry.

Concept introduction: Speciation is part of evolution where new species arise from existing species as a result of evolutionary mechanisms. Allopatric speciation occurs when geographic isolation restricts the gene flow, whereas sympatric speciation does not occur due to geographic isolation and may be caused by certain mutation, natural or sexual selection. Sympatric speciation is a type of speciation where new species evolve in the same geographical area of their ancestral species and both the newly evolved species and the ancestral species are in the same geographical location.

There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?
