Hitchhicker's thumb is a condition in which a person is able to bend his thumb backwards. This trait can be seen in many people but the condition is recessive, which means a person needs two alleles for hitchhiker's thumb to have this particular characteristics. The gene for straight thumb is commonly indicated by T while that for hitch hicker's thumb is indicated by t.
Let's see what will happen if a person heterozygous for hitchhiker's thumb marries a woman who is also heterozygous for hitchhiker's thumb.
P1: Tt X Tt
Gametes: t T : t T
Offsping : TT : Tt : tT : tt
TT : 25 % : Straight thumb
Tt + tT : 50% : Straight thumb
tt : 25% : Hitch hicker's thumb
Therefore, there are 25 % chances that their offspring will have Hitch hicker's thumb and 75 % chances that they will have straight thumb.
Hope it help!
Answer:
Hypothesis - a guess what might happen during the experiment.
It is the third step of the scientific method.
Steps of the scientific method:
Step 1: make a question
Step 2: do some research for that question
Step 3: make a hypothesis
Step 4: Test the experiment and collect data
Step 5: Conclusion ( what you learned from the experiment)
The three main stages of aerobic cellular respiration include the following:
- Oxidative phosphorylation.
<h3>What is Cellular respiration?</h3>
This is referred to as the different metabolic reactions which takes place in cells in the presence of oxygen and converts chemical energy into Adenosine triphosphate and some waste products.
This type of respiration is divided into three main categories which can be seen above and is therefore the reason why option C was chosen.
