16、 One Father of Genetics21Think and Talk Mendel worked with seven characteristics of pea plants:plant height,pod shape and color,seed shape and color,and flower position and color.Taking seed color as an example,Mendel showed that when a true-breeding yellow pea and a true-breeding green pea were cro

17、ss-bred their offspring always produced yellow seeds.However,in the next generation,the green peas reappeared at a ratio of 1 green to 3 yellow.To explain this phenomenon,Mendel coined the terms“recessive”and“dominant”in reference to certain traits.In the preceding example,the green trait,which seem

18、s to have vanished in the first filial generation,is recessive and the yellow is dominant.Reference22Part III-Video OneThink and Talk He published his work in 1866,demonstrating the actions of invisible“factors”now called genesin predictably determining the traits of an organism.The profound signifi
