Question
In a typical one trait experiment of Mendel's, yellow pureline peas (YY) are crossed with green pureline peas (yy). The offspring are yellow. Then, those offspring are selfed. Which statements are / would be true about this experiment?
best answer.
O (A) Yellow is the dominant phenotype. The F1 should have phenotype ratio of 3:1
yellow to green, and a genotype ratio of 1 YY :2 Yy: 1 yy.
(B) Green is the dominant phenotype. The F1 should have phenotype ratio of 3:1 green
to yellow, and a genotype ratio of 1 YY: 2 Yy: 1 yy.
(C) Yellow is the dominant genotype. The F2 should have phenotype ratio of 3:1 yellow
to green, and a genotype ratio of 1 YY: 2 Yy :1 yy.
O (D) Green is the dominant genotype. The F2 should have phenotype ratio of 3:1 green
to yellow, and a genotype ratio of 1 YY: 2 Yy : 1 yy.
O (E) Green is the dominant phenotype. The F2 should have phenotype ratio of 3:1 green
to yellow, and a genotype ratio of 1 YY: 2 Yy:1 yy.
O (F) Yellow is the dominant phenotype. The F2 should have phenotype ratio of 3:1
yellow to green, and a genotype ratio of 1 YY:2 Yy:1 yy.
