Answer:
the wings on bees and birds
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
I think the correct answer among the choices listed above is option A. All of the following are abiotic factors in an ecosystem except algae. Abiotic factors is concerned on the non-living parts of the environment that affect organisms.
