Explanation:
How Are Men Affected by Cystic Fibrosis? Males account for slightly more than 50 percent of all cases of cystic fibrosis (CF) but generally have better outcomes than females until about age 20.
The answer is.......4!!
Explanation: All you have to do is 12/3.0 and you will get four!
Answer:
2% of the progeny will be double crossovers for the trihybrid test cross
Explanation:
By knowing the positions of genes, we can estimate the distances in MU between them per region.
- Genes A and B are 10 map units apart (Region I)
- Genes B and C are 20 map units apart (Region II)
- Genes A and C are 30 map units apart
----A-------10MU--------B-------------20MU-------------C---
Region I Region II
We can estimate the recombination frequencies by dividing each distance by 100.
• recombination frequency of A-B region = 10MU / 100 = 0.10
• recombination frequency of B-C region = 20MU / 100 = 0.20
Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:
EDRF = recombination frequency in region I x recombination frequency in region II.
EDRF = 0.10 x 0.20 = 0.02
2% of the progeny will be double crossovers for the trihybrid test cross
Maybe it’s not a mineral because it’s just hardened tree resin whereas minerals can be mined and found deep in the earth…?
