Guard cells in plants control water pressure
Answer:
The progeny produced is 100% heterozygous individuals.
Explanation:
Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.
When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.
If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.
As for its phenotype, it will depend on which allele is dominant over the other.
B) they work independently of one other
It is known as stimulus or the plural form stimuli. It can be external or internal.
Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
