What is a germ cell mutation?
A germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ovum). Mutations in these cells are the only mutations that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote.
What is affected in a germ cell mutation?
Somatic mutations differ from germ line mutations, which are inherited genetic alterations that occur in the germ cells (i.e., sperm and eggs). Somatic mutations are frequently caused by environmental factors, such as exposure to ultraviolet radiation or to certain chemicals.
The bright yellow blooms of daffodils are a wonderful sign that spring has arrived. The daffodil is virtually synonymous with spring. Though their botanic name is narcissus, daffodils are sometimes called jonquils, and in England, because of their long association with Lent, they're known as the "Lent Lily." Lore connecting the daffodil to not only a sign of winter's end but a lucky emblem of future prosperity is found throughout the world. In Wales, it's said if you spot the first daffodil of the season, your next 12 months will be filled with wealth, and Chinese legend has it that if a daffodil bulb is forced to bloom during the New Year, it will bring good luck to your home.
