Y-Linked Traits

Y-linked traits appear only in males and are passed from a father to all his sons.

Does not skip generations. Example – Hypertrichosis, Webbed toes

If the number of phage particles is two or more, it is more likely to produce lysogney. And as the numbers of phage per cell become lower and lower, the tendency toward lytic infection increases, and as it becomes higher and higher, the likelihood of lysogeny similarly increases.

Lytic growth proceeds when PL and PR remain switched on while PRM is kept off. Lysogenic growth, in contrast, is a consequence of PL and PR being switched off and PRM switched on.
