Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine .
Answer:
a) 9%.
b) 16.8%.
Explanation:
a).
We are provided with the information that Two linked genes, A and B, are separated by 18 cM (centiMorgan). i.e the recombinant frequency is 18%
Also , the man's genotype is AB/ab... This only result to one explanation, that The man will definitely produce 18% of recombinant gametes which entails
9% Ab & 9% aB
i.e 0.09 Ab & 0.09 aB
On the other-hand, The mother ab/ab have tendency to produce just one single type of gamete which is ab
∴
The probability that their first child will be Ab/ab will be
Pr ( Ab/ab) = (0.09) x (1)
= 0.09
= 9%.
b).
If the father produces 18% of recombinant gametes which entails
9% Ab & 9% aB , this typically implies that the number of the non-recombinant gametes will be;
100%-18% = 82% ( non-recombinant gametes)
i.e genotype AB/ab = 82%
AB =41%; ab = 41%
AB = 0.41 ; ab = 0.41
Now, the probability that their first two children will both be ab/ab:
Using Multiplication Rule to calculate the probability that their first two children (ab/ab); we have:
(0.41)(1) ×(0.41)(1)
= 0.1681
= 16.8%.
Joseph Unahue made his fortune in "Food Distribution"
<u>Answer:</u> Option C
<u>Explanation:</u>
The Nuyorican president of Goya Food named Joseph Andrew Unanue. The firm was largest United States owned Hispanic food company, operated by the Unanue family.
He enrolled at the Catholic University of America in Washington, D.C., in 1946, after Unanue returned home from battlefield of World War-II, where he graduated with a degree in Mechanical Engineering. Along with his brothers Tony and Frank Unanue, he joined the family business.
Firstly major supermarkets like A&P and Safeways were not motivated in selling anything considering the Hispanic demographics.Finally, the grocery industry began to take note with the influx of Hispanic immigrants settling in the United States. Goya Foods started supplying "Safeway's Harlem Grocery" and developed ahead.
Because it helps them with finding new researches.
