Yesterday was the birthday of Anna’s Great-Aunt Katherine, with whom she shares the shape of nose. Anna’s father, who died on July 20, also had that nose shape. He had a bad back, too, once hospitalized after bending to pick up a shaving cream top. Ten years ago today, Anna’a sister was hospitalized when her back went out. How do we know why family members share traits?
On this date in 1822, the father of genetics, Gregor Mendel was born (some report July 22, likely his baptismal day). Motivated by a repetitive and isolated monastic life, Mendel spent much of his time studying and meticulously recording inherited traits in pea plants, and then in bees. During his lifetime, his biology work wasn’t much touted, but his peers liked what he had to say about meteorology so he founded a society for that.
