Race of inbred plant has a mean petal length of 12 mm, a second race from another location has the same meant petal length. When the two races are crossed, the F1 also has the mean petal length of 12mm. However the F2 generation derived from crossing the F1 to one another shows a very wide spread in plant length. About 3 out of 770 have a length as small as 8 mm. And about 3 out of 770 have a length of 16 mm. How many allelic pairs seem to be involved in the different petal length? How much does each effective allele contribute to

The ancestors of plants that lived in water had plenty of water for the young. angiosperms are a group of land plants that evolved a reproductive trait for living on land. this trait protect young plants by allowing them to grow only when water is present and the conditions for healthy development are right. what trait most likely young angiosperms in this way?

Explain the difference between mutations in sex cell and those in somatic cells
