Answer:
it's 25%
Explanation:
the recessive is two r and one R is makeing the gene dominant. Heterozygous is Rr and two make 75% dominant and 25% recessive
Answer:
Answer would be no.
B)carbon, hydrogen and oxygen
Answer:
When they grow bigger or there are some differences that haven't been there before? (Ex. Spots, stripes, Longer tusks)
Explanation:
I'm just thinking of this logically ok so don't know if this is correct but hope this helps.
Answer:
The purpose of the outer covering of the bird helps keep it warm and to help it fly, whilst the outer cover of the tree is to protect it from bugs.
Explanation:
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
