However, none of the 100 seeds with regular light sprouted, or even grew roots, leaving us with a sample size too small to determine anything from.]]> 2017-05-05 12:31:21 UTC https://padlet.com/rford9/jvuhdxea3uri/wish/170158489 aajohnalo https://padlet.com/rford9/jvuhdxea3uri/wish/170159442 Half (50%) of the seeds that sprouted were white, instead of the normal 25% expected from a recessive trait from heterozygous parents. Because of this, we can justify  our statement (explanation 2), because the seeds exhibited a change in phenotypic ratio, as our explanation predicted. However, we cannot fully determine a creditable justification because we had a very small sample size. ]]> 2017-05-05 12:35:44 UTC https://padlet.com/rford9/jvuhdxea3uri/wish/170159442
