The answer to the question above is letter B. In humans, having freckles is the result of a dominate gene and not having freckles is a recessive trait. If the freckled man is homozygous and the woman doesn't have freckles then the child would have freckles.
They will be 100% heterozygous
Answer:
The correct answer is: Attachment.
Explanation:
- Pilus are thread like structures which are present on the surface of the bacterial cell.
- They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
- Pilus also mediate the process of conjugation in some bacterial cells.
- Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
- Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
- A defective pilus will affect all the above processes, resulting in death of the bacteria.
I believe the correct answer is *B* <span>mitosis; differentiation </span>
Since PKU is a recessive disease, each parent's genes can be represented by pp. When you complete the Punnett square the results in each square are pp. So, since all of the square have pp, there's a 100% chance.
