What is the genotype of a female with hemophilia?
Females having one normal and one abnormal gene are asymptomatic carriers and will transmit the abnormal gene, on average, to one half of their sons and one half of their daughters….Expression and Transmission.
| Phenotype | Genotype |
|---|---|
| Carrier female | XhXH |
| Affected female | XhXh |
What must be the genotypes of the parents of a colorblind daughter explain?
A colour blind daughter therefore must have a father who is colour blind and a mother who is a carrier (who has also passed the colour blindness ‘gene’ to her daughter). If her father is not colour blind, a ‘carrier’ daughter won’t be colour blind.
What is the blood type of the father if the daughter is type O and the mother is type A?
type AB
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter….How are ABO alleles inherited by our children?
| Inherited | Blood type of child |
|---|---|
| O from the mother B from the father | B |
What is the genotype of a colorblind woman?
Females that are X+X+ or X+Xc have normal color vision, while XcXc females are colorblind. Males that are X+Y have normal color vision, while XcY males are colorblind. To determine the inheritance of red-green colorblindness (or any other X-linked trait), the genotypes of the parents must be considered.
What genotypes would the parents have to be to have a child with hemophilia?
The father’s sex chromosomes are labeled XY, with the X chromosome carrying the hemophilia gene. The father only passes half of his sex chromosomes to the baby, either the X or the Y. If the baby gets the Y chromosome from the father it will be a boy.
What is the genotype of the mother?
The mothers genotype is AO. The fathers genotype is BO. The genotypes of each child is OO for the child with type O blood and BO for the child with…
What is the genotype of a male with red-green color blindness?
Now that we determined that Audrei is homozygous recessive for the red-green color blind allele. What is her father’s genotype? Audrei’s father is color blind….Problem 2: Sidney’s genotype.
| Male Genotype | Male Phenotype |
|---|---|
| XR Y | Normal Vision |
| Xr Y | Red-green color blind |
What would be the parents genotype for color of a black offspring were produced from two white sheep?
If a cross between two white sheep produces offspring with a black coat (ww), this means that both parents have the recessive allele and are both heterozygous (Ww).
What genotype does a person with O blood have?
OO
Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
What is the genotype of the male parent?
Bb
The male parent is heterozygous which means he has one allele for black eyes and one allele for red eyes. Since his eyes are black, this means that black allele must be dominant over the red allele. So the male parents genotype is “Bb” (B= allele for black eye, b=allele for red eye).
What is the blood type of a mother and child?
For instance – Mother with AB blood type can either pass the A or B allele to the baby. If both parents belong to the blood group O, the child will also belong to the O blood group. Two A blood group parents can give their child either A or O blood group. Two B blood group parents can give their child either B or O blood group.
Can two people with A and B blood types have a child?
One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Can the ABO blood type charts be used to predict paternity?
The ABO blood type charts below can be used to predict the possibilities of paternity. 1. The ABO blood type of the child when the blood type of the father and the mother are known (top chart), or 2. The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart).
How can I find out the blood type of my child?
Select the mother’s and the father’s blood type and you can find out the probable blood group of your child. Blood groups were discovered in the 20th century when Karl Landsteiner observed that the red blood cells (RBCs) had specific substances on their surfaces, which were later used to create blood types.
