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

An invertebrate, because an animal with a vertebrate is an animal with a backbone.
by the law of natural selection, daddy charles darwin stated that overpopulation could result in famine and wars, and death would accelerates across nations, so overpopulation is a cause for this because of too many organisms but not enough food, which declined growth rate.
There are several reasons that contribute to the high level of biodiversity found in the wetlands. Firstly it provides numerous animals and insects to find their food and breed easily. Also this wetland helps the animals to camouflage against their enemies. The wetlands provide home for abundance of marine animals. It is actually a place that maintains a natural balance.<span />
