What is the phenotype of a child whose father has brown eyes and mother who has blue eyes?
Brown eye gene = B
Blue eye gene = b
Each person has two copies of the eye color gene in their genome, one inherited from each parent. Now if both parents only carry the gene for brown eyes, BB and BB, then their child will receive one B from each parent, ending up as BB. The same works for blue eyes, if that's the only gene both parents carry, bb and bb. Each parents gives on b to the child, who ends up as bb.
In this case the child will have a 50:50 chance of brown eyes if the father carries the gene for blue. But if he carries both genes for brown the child will have brown eyes.
What else can I help you with?
A child has brown hair and brown eyes His father has brown hair and blue eyes His mother has red hair and brown eyes The best explanation for the child having brown hair and brown eyes is that?
The child inherited both the genes for brown hair and brown eyes from both parents, as brown is likely a dominant trait in this case. The child also carries the genes for blue eyes from the father and red hair from the mother, but the dominant brown traits are expressed in the child's appearance.
What is the expected phenotypic ratio among children born to a mother having the genotype IAiO and a father with the phenotype AB?
Because the actuality of IAIA is actually A then the father would be type A and the mother being type O they would produce children of Type A blood type. For the answer I chose A) A... I just had this on my Bio exam.
Can a mother with AB and father with O have a child with A blood?
NO
If mother has blood type A and the father has blood type O what are the possible blood type outcomes of their offspring?
The mother would be AB. * The mother could be A or AB. The explanation: Dad shows the recessive trait (type O), so must have two copies of the recessive allele (his genotype is ii). So the son must have inherited a copy of the recessive allele from Dad. But Junior is type A, so must have a copy of the IA allele. That must have come from Mum. To pass on the IA allele, Mum must be either IAIA (type A) or IAIB (type AB).
What color eyes will the child have father has grey eyes mother has blue eyes?
well it depends on if the mother has one trait for blue eyes or not. if the mother does then there is a 1/4 chance that the child will have blue eyes and a 3/4 chance that the child will have brown eyes but if the mother does not have a blue eyed gene and she carries 2 genes for brown eyes then your child is going to have brown eyes. but no matter wat color your child's eyes are he/she will carry one gene for blue eyes and will have a possibility to pass down blue eyes to his/her child
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.
Can A positive father and A negative mother produce a O positive child?
Yes. The father's phenotype is AO+*; the mother's is OO--.
Can an O negative mother and an A positive father produce an O positive child?
Yes. The father's phenotype is AO+*; the mother's is OO--.
Can an a positive father and an b negative mother have an ab negative child?
yes it dependsupon the genotype and phenotype
Can child have o type blood from AB mother and A father?
No. For the child to have a phenotype of O, they require an oo genotype. As the mother cannot provide one O to this, this is not possible.
If the father has green eyes the mother has brown eyes the mother's father has blue eyes what color will the child's eyes be?
i m pretty sure that child will have purple eyes
What colour eyes will child have father has green mother has brown eyes?
brown eyes because brown is the dominant color :)
Can a father with type B pos blood and a mother with type a pos blood produce a child with type O pos blood?
Yes. The genotypes of the father could be BO or BB (Phenotype = B) The genotype of the mother is OO(Phenotype = O) Mating these genotypes will produce either OO (Phenotype O) or BO (Phenotype B) In short, children from these parents are B or O The Rhesus(D) positive was inherited from the father.
Can a green eyed mother and blue eyed father have a brown eyed child?
Yes
A child has brown hair and brown eyes His father has brown hair and blue eyes His mother has red hair and brown eyes The best explanation for the child having brown hair and brown eyes is that?
The child inherited both the genes for brown hair and brown eyes from both parents, as brown is likely a dominant trait in this case. The child also carries the genes for blue eyes from the father and red hair from the mother, but the dominant brown traits are expressed in the child's appearance.
If the father has black hair and the mother has dark brown hair can the child have black hair?
yes it can
Can a brown-eyed father and a blue-eyed mother have a blue-eyed child?
yes, but rarely.
