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

Explanation:
Inflammation is the body defence system against various pathogens and include various components such as Immune cells and blood vessels. Inflammation occurs in a sequence of events.
- when a pathogen enters the cells macrophages produce the first response by phagocytizing the foreign body.
- The blood vessels dilated so more blood cells, oxygen and nutrients could reach at the site of pathogen and fight against it.
- Foreign pathogen is captured at that place so it can't mobilize to other part of the body.
- The more fighting cells are directioned at the site of infection
- The recruited phagocytic cells phagocytize the invaders pathogen and starts its degradation.
Answer:
It can be harmful in many ways
Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.
