Answer:Codominance, as in human blood type, is a form of inheritance in which both alleles are expressed equally in the phenotype of the heterozygote.
Explanation:
Answer:
3:1
Explanation:
Let the allele for tall plant be T; &
The allele for short plant be t
When Mendel crossed true-breeding tall pea plants(i.e TT) with true-breeding short pea plants(I.e tt); all the offspring were tall.
TT × tt
T T
t Tt Tt
t Tt Tt
we can deduce from the punnet square that the F1 offspring are all heterozygous tall plant.
Now, if the first generation (F1) tall plants are allowed to self-pollinate; we have a cross between Tt and Tt
TT × tt
T t
T TT Tt
t Tt tt
We can see phenotypically that we have 3 tall plant(TT,Tt, Tt) and 1 short plant(tt).
Therefore the ratio of phenotypes he expected in the F2 generation is (3:1)
A
There would bot be enough for everyone affected. The level of production is clearly insufficient to supply vaccines to all countries.Only a limited number of vaccine does would be available, particularly in the early stages of pandemic and most of them would be supplied to industrialized countries. Developing countries will be forced to confront the next pandemic with few or no available vaccines.
