The observed distribution of alleles into gametes is an illustration of Mendel’s law of segregation and independent assortment.
Mendel's law of independent assortment - the alleles a gamete receives get sorted into gametes independently of one another (one gene does not influence the allele received for another gene).
Mendel’s law of segregation - each gamete receives one gene copy selected randomly.
The correct sequence of events for muscle contractions is as follows : :
1. motor neuron action potential.
2. neurotransmitter release.
3. muscle cell action potential.
4. calcium ion release from SR.
5. ATP-driven power stroke.
6. sliding of myofilaments neurotransmitter release.
The patellar region has a reflex (when the doctor hits your knee with that little rubber hammer and you kick your leg). Any reflex protects us from harmful things. The kneecap also covers and protects the anterior articular surface of the knee joint.
