Answer:
The chance that their <u>child will not be able to roll his tongue will be zero</u>.
The chances to have a child with tongue rolling ability is 100%.
Explanation:
In complete dominance, a dominant gene completely manifests over a recessive gene. If tongue rolling is a dominant trait, this means that the gene that expresses this trait is dominant over the recessive one that does not allow the person to roll the tongue.
If the gene for tongue rolling is called T, then a person that is homozygous dominant for this trait will have the following genotype: TT. If the person is heterozygous for this trait, the genotype will be Tt. And if a person is homozygous recessive for the trait, this person´s genotype will be tt.
When two homozygous dominant individuals mate, their chances to have a child with tongue rolling ability is 100%.
This is:
Parental) TT x TT
Gametes) T T T T
Punnet Square) T T
T TT TT
T TT TT
F1) Genotype: 100% TT, or 4/4 TT
Phenotype: 100% Tongue rolling capable.
It is much likely that the mother will suffer from pneumonia. Fetus is likely to suffer from birth defects known as varicella syndrome if it occurs at a gestation of 8-20 Wks (skin scaring, underdeveloped arms and legs, incomplete brain development)
if the infection is within 48yrs before a delivery child may suffer from neonatal varicella which is life-threatening
Oil is organic solvent and dissolve in organic solvent while water is inorganic solvent and we also know that like dissolves like
I'm not sure if this helps but I think that oxygen moves into and carbon dioxide leaves it.
