The answer is speciation. It could have been caused by the separation
of the two populations by a geographical feature such as a wide river (hence causing allopatric speciation) or could
have been caused by behavioral isolation
between the two population (hence causing sympatric
speciation).
Answer:
120 white individuals
30 yellow individuals
10 green individuals
Explanation:
Available data:
- Dominant epistasis: Phenotypic frequencies 12:3:1
- W allele codes for a dominant white phenotype
- w allele codes for a colored squash
- Y allele codes for a dominant yellow phenotype
- y allele codes for a recessive green phenotype
- W allele will always mask the phenotype produced by Y or y alleles

F1 Phenotypic Frequency)
White phenotype: 12/16 = 120 individuals
Yellow phenotype: 3/16 = 30 individuals
Green Phenotype: 1/16 = 10 individuals
To know how many offspring are expected to have the white, yellow, and green phenotypes, you can perform a three simple rule. This is:
16 ------- 160 offspring
12 White ------- X = 120 offspring
3 Yellow ------- X= 30 offspring
1 Green --------X = 10 offspring
The heat causes them to open up and flow air
Answer:
1) habitat
2) overpopulation
3) habitat (again I guess?)
5) shelter
Explanation:
I can't think of anything else for 1 and 3.
