It is located in a nucleus like organelle called the nucleoid
Answer:
500
Explanation:
Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time
So given that;
the mutation rate of a particular gene = 1 × 10⁻⁶
The expected mutations after 500 million sperm are examined will be:
= (1 × 10⁻⁶)×(500,000,000)
= 500
Thus, The expected mutations = 500
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
