The phenotype ratio would be 25% each for widow's peak and freckles, widow's peak without freckles, straight hairline with freckles, and straight hairline without freckles.
<h3>Dihybrid crossing</h3>
Genotype of the heterozygous parent: HhFf
Genotype of the other parent = hhff
Crossing the two parents:
HhFf = 1/4 = Widow's peak, freckles
Hhff = 1/4 = Widow's peak, no freckles
hhFf = 1/4 = straight hairline, freckles
hhff = 1/4 = straight hairline, no freckles.

Answer:
separation of populations has led to the evolution of new species
Explanation:
- When the populations evolve to become distinct species, then this process is termed as speciation.
- Speciation can occur due to various reasons and one of these reasons is geographic isolation that leads to separation fo the populations which then faces different evolutionary pressure and thus evolve into new species.
- In the Hawaiin islands, there are different species of honeycreepers because of the unique geology of Hawaii due to which new volcanic islands are constantly being formed and eroded which leads to the separation of population and their evolution into new species.
Answer:
1) The brown gummy would be going through a Food & Beverage. The ink pen and note would be going through Chromatography. The white powder would be going through Qualitative analysis.
2) The gummy would be tested for food safety, nutrition, and quality. The ink pen would be tested for separating a mixture of chemical substances into its individual components. The white powder would be tested for a reaction.
3) The method would work for the brown gummy to see why it's brown, how long has it been sitting out, and is there any connection to the case. The method would work for the ink pen and note so it can be thoroughly analyzed to see if it was written in a distressing or frightening matter. The method for white powder would work to determine if it's narcotics or just baking powder.
