Cystic fibrosis is a genetic disorder in homozygous recessives that causes death during the teenage years. If 9 in 10,000 newbor
padilas [110]

Answer:

f(A1) = 0.9700, f(A2) = 0.0300

Explanation:

The frequency of homozygous recessive genotype of children is  

\frac{9}{10000} \\= 0.0009

As per Hardy weinberg's equation, frequency of homozygous recessive genotype is represented by  

q^2

Here q^2 = 0.0009

Thus, frequency of recessive allele would be  

\sqrt{q^2}\\ = \sqrt{0.0009}\\ = 0.03

as per first law of Hardy weinberg

p+q = 1\\p = 1- 0.03\\p = 0.97

Hence, option C is correct

Louis Pasteur proved that all new cells come from preexisting ones. What concept did Pasteur’s experiments disprove
Brilliant_brown [7]
Louis Pasteur’s experiments has taken a leap on cell biology. He was able to contribute to the concept of cell theory which suggests that cells came from pre-existing cells, cells are the fundamental unit of life and that all life have cells.

Highlighting on pre-existing cells, early before the experiments of Pasteur, there was the theory of spontaneous generation. This theory claims that organisms came from nonliving objects which is now, truly misleading and wrong.

Describe two inheritance patterns besides simple dominance
Phantasy [73]

Explanation: All of it is in gamete formation. Meaning, it is going through a gamete formation which also means that pairs of alleles that are for different traits, segregate. They move on independently from one another, never touching.

For your question, It's incomplete dominance which is when cases with one allele isn't complete to be dominant over another allele. It's all got to come together in order for it to become a strong and dominant allele, or else it won't be complete and won't become and do what it has to.

I hope this help you and I hope that I gave you what you wanted/needed for this question.
