During meiosis, the process of crossing over results in new combinations of alleles because
A.
genetic material is added by a third chromosome during this process.
B.
genetic material is exchanged between chromosomes during this process.
C.
genetic material always mutates randomly during this process.

genetic material is removed during this process.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
