True I’m pretty sure I just checked it and it said true so
Answer:50% chance possible offspring
Explanation:
Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.
Hope it helps!!
The correct answer is d. both excitation and inhibition.
There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).
