Bacilli, cocci, and spirilla
If brown is dominant (B) and white is recessive (b), then for this cross of 2 white mice, you are crossing bb x bb ---- so the only mice you can end up with will be white!
Answer: 0%
Answer:
12%
Explanation:
The genes E/e and F/f are 24 cM apart.
- E_: elongated wings
- ee: small wings
- F_: five stripes
- ff: four stripes
A distance of 24 cM means that the frequency of recombination between the two genes is 24%.
The cross Ef/eF x ef/ef would produce the following offspring:
- Ef/ef: Parental; elongated wings and four stripes
- eF/ef: Parental; small wings and five stripes
- EF/ef: Recombinant; elongated wings and five stripes
- ef/ef: Recombinant; small wings and four stripes
The total percentage of recombinant gametes is 24%, and there are two possible recombinant gametes, so each of them appears in 12% of the cases.
The individuals with elongated wings and five stripes have the recombinant genotype EF/ef, therefore the percentage of the offspring with this phenotype is 12%.
Parasitic diseases and predator/prey relationships are all examples of exploitation factors in an ecosystem.
Hope this helps you! :)
