Copyright © by Holt, Rinehart and Winston. All rights reserved. Characteristics Mendel studied only one characteristic at a time. Characteristics- seed shape plant height flower color Section 1 Mendel and His Peas Chapter C3 + 1 each = 2 pts

Copyright © by Holt, Rinehart and Winston. All rights reserved. Mix and Match Mendel wanted to find out what would happen if he bred or crossed two plants that had different traits of a single characteristic. Section 1 Mendel and His Peas Chapter C3 + 1 each = 1 pt

Copyright © by Holt, Rinehart and Winston. All rights reserved. Pea Plant Experiments: What were his results? One trait was always present in the first generation and the other trait seemed to disappear. the trait that appeared =dominant trait. The trait that seemed to disappear = recessive trait. Section 1 Mendel and His Peas Chapter C3 Mendel’s 1 st Experiments + 1 each = 3 pts

Copyright © by Holt, Rinehart and Winston. All rights reserved. In second-generation, the recessive trait reappeared. MOST plants had the dominant trait. Section 1 Mendel and His Peas Chapter C3 Mendel’s 2 nd Experiments + 1 each = 2 pts

Copyright © by Holt, Rinehart and Winston. All rights reserved. The ratio between dominant & recessive traits The ratio was always about 3:1 (dominant : recessive) Section 1 Mendel and His Peas Chapter C3 + 1 pt

Copyright © by Holt, Rinehart and Winston. All rights reserved. What conclusions did he make? His results could only be explained if : each plant had two sets of instructions for each characteristic. each parent donated one set of instructions Section 1 Mendel and His Peas Chapter C3 + 1 each = 2 pts
