In an experiment, mendel grew 633 green pea plants with either wrinkled seed-coats (dominant) or smooth (recessive). if the ratio of the wrinkled seed-coat plants to the smooth seed-coat plants was 3: 1, how many smooth seed-coat plants did he grow? a) 158 b) 211 c) 633 d) 844

There are 158 smooth seed coat plants he grew.

Explanation:

Since we have given that

Total number of green pea plants with either wrinkled or smooth = 633

Ratio of wrinkled seed coat plants to the smooth seed coat plants = 3:1

So, Number of smooth seed cost plants that he grow is given by

Hence, there are 158 smooth seed coat plants he grew.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
