"Men have one X chromosome, from their mother, and one Y chromosome, from their father. Because of this, a man will pass his copy of the X chromosome—and the genes it contains—only to his daughters and his copy of the Y chromosome only to his sons. Women have two alleles of every gene on the X chromosome, one inherited from their father and one from their mother. Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father."
The child inherited features through DNA from both parents is the correct answers.
Explanation:
It is necessary to remember that the child receives the chromosomes from his parents: the mother gives him one X chromosome while the father gives the child an X chromosome. Due to this, the child receives characteristics from both of them,<u> which result in the blue eyes and the curly hair.</u>
Most likely a silent mutation. Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype because the same amino acid is produced regardless of the change in the nucleotide sequence by the mutation.
They are not violent killers because they need their host to stay alive for their benefit And if the host dies the parasite wont have a host so they try to keep it alive for as long as possible.
