The Phenotype would be a straight hairline. The genotype would be aa.

What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
What blood type would a baby have if both parents have blood type O positive?
The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO. The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO. If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype. If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance). * Phenotype = displayed trait that can be found with a simple blood test. * Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.
Can an a positive father and an b negative mother have an ab negative child?
yes it dependsupon the genotype and phenotype
Is the characteristic of a child dominant if the parent does not possess it?
Yes. It does not matter if the mother or father does not have a characteristic that the child has possessed
Can a child be afflicted with a dominant trait if both her parents have a normal phenotype Why or why not?
YES SOMETIMES THAT IS NOT LIKELY.
Both a man and a woman are heterozygous for freckles Freckles F are dominant over no freckles f What is the chances that their child will have freckles?
PHENOTYPE: 75% with freckles 25% without freckles GENOTYPE: 1FF:2Ff:1ff
What is the phenotype of the child if the father has brown eyes and mother has blue eyes assuming a complete dominence and recessive relationship between brown eyes and blue eyes?
If assuming that the dominance relationship is that the brown eyed gene is dominant over the blue eyed gene. Then the child's phenotype should be brown eyes.
What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?
The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.

The phenotype of a child is determined by the interaction between a pair alleles of and their interaction with their environment .
A trait that is masked by a dominant trait is called?
DNAactually it is not DNA at all, a dominant trait, masks a recessive trait.
What happens when a dominant and recessive allele are both present?
The resulting offspring will have the dominant trait. It depends on if the dominant is hetero or homo...if it was homozygous then your offspring will have a hetozygous trait showing the dominant trait (to clear this up if you are confused lets say we are talking about brown eyes(BB-dominant) vs blue eyes(bb-recessive)--a homozygous would give you a brown eyed child with Bb and but if the person is heterozygous Bb and gets with a recessive you have a chance of getting Bb or bb giving you a possibility of a brown or blue eyed child)...wow i just made that way more confusing than it had to be
