Vertical Alignment:
The type of reproduction determines the diversity of the offspring.
The student knows that reproduction is a characteristic of living organisms and that the instructions for traits are governed in the genetic material
7.14A – Define heredity as the passage of genetic instructions from one generation to the next generation
7.14B – Compare the results of uniform or diverse offspring from sexual or asexual reproduction (
7.14C – Recognize that inherited traits of individuals are governed in the genetics material found in the genes within the chromosomes in the nucleus(
