Answer:
eight (8)
Explanation:
A phenotypic ratio of 9:3:3:1 is predicted from a cross of AaBb x AaBb (i.e., in a dihybrid cross). In this case, the expected phenotypic ratio is equal to:
A_B_ (9:3:3:1) =71.43 >> 71 both dominant phenotypes
aaB_ (9:3:3:1) = 23.81 >> 24 one dominant phenotype
A_bb (9:3:3:1) = 23.81 >> 24 one dominant phenotype
aabb (9:3:3:1) = 7.93 >> 8 both recessive phenotypes
Expected phenotipic ratio (9:3:3:1) = 71 + 24 + 24 + 8 = 127
Answer:
Explanation:
It is important that a cell undergoes replication before cell division occurs because, the main goal of cell division is to make more cells. And for all these cells to remain functional, all their components must be intact and complete. without this, these cells might not function. Thus, the goal of replication is to produce the next new copy that would go into one of the daughter cells produced. With DNA replication, the set of DNA present in a cell can be duplicated and then each daughter cell that results from division can have its own entire set of DNA and then cell division can theoretically continue as normal indefinitely.
Gymnosperms have cones, they’re sporophytes, so they’re capable of producing spores, they do reproduce by pollination and they’re vascular :)
