Answer:
<h2>50 %
</h2><h2>16.4%</h2>
Explanation:
Huntington's disease: is an autosomal dominant disorder.
given
male = Hh
female = hh
H =dominant allele
h = recessive allele
All child inherit one allele from each parent, one from father and one from mother.
So parents are
1).
Hh and hh
F1 progeny are (Hh, Hh, hh and hh)
50% show Huntington's disease ( Hh, Hh)
so there are 50% chances that first child have Huntington's disease
2).
Any two of the seven children will have Huntington's disease
<h2>=16.4%</h2>
Answer:
2.Scientific inquiry. It is the same as Science Method.
There are 5 steps :
1. Ask a question
2. Do some research for that question
3. Hypothesis ( guess what is going to happen during the experiment )
4. Test the experiment and collect the data .
5. Conclusion ( say what you learned from the experiment)
Answer:
The correct answer is option D. The cells do not produce functional motor proteins in flagella and cilia.
Explanation:
Primary ciliary dyskinesia or PCD is a very rare autosomal recessive disorder that is characterized by severe respiratory problems, Fallopian tubes, and the sperm cells flagella due to the defects in the lining of cilia present in these structures.
This recessive trait affects the gene that is responsible for the production of the motor protein for cilia and flagella and inhibits its production.
Thus, the correct answer is option D. The cells do not produce functional motor proteins in flagella and cilia.
