What else can I help you with?
Can a child be O negative if the parents are O positive and their are three grandparents who are O positive and one is B negative?
Yes.
Can a child be O negative if both parents are O positive and three of the grandparents are O positive and one is B negative?
It is possible as the Rhesus factor is a dominant trait. So, even if the parents have only one allele for the factor, there is a 1/4th chance that the child could get neither allele from the parents and end up as O negative.
Did newton have grandparents?
Yes, its a fact of biology, that every human has two parents, and those two parents have two parents each. So somewhere in the past lived four individuals that aided in the creation of the three laws of motion.
How many syllables in the word grandparents?
There are three syllables in the word "grandparents".
How do you qualify to play rugby for England?
There are three ways a player qualifies to represent a country: through his or her birth, that of parents or grandparents, or residency which requires someone to live in their adopted nation for three successive years.
How many generations are shown in a pedigree?
A pedigree typically shows three generations: the top generation represents grandparents, the middle generation are the parents, and the bottom generation includes the children.
If you have black socks and brown socks in your drawer mixed in a ratio of 4 to 5 how many socks will you have to take out in order to have a pair of the same color?
omg math! omg math! omg math! another person-three. if you pull out three socks, here are all the possible ratios. black, black, brown brown, brown, black black, black, black brown, brown, brown
Is it possible for a black haired parent and a brown haired parent to have a child with blonde hair if all the grandparents of said child has either black brown or dark auburn hair?
You should be aware that the color of a child's hair can change as it grows up. When I was 7 my hair was silvery blond - by the age of 20 I was dark brown.On top of this the genetics for hair color are not simple (there is more than one gene involved). Look in the link I will place below. Yes, this is perfectly possible. Genes (sections of your DNA in each cell) determine, among other things, hair colour and are either 'recessive' or 'dominant''. the two different kinds of gene (dominant or recessive) are called alleles. The allele for brown or black hair is dominant over the blonde hair allele which means that when a child inherits a gene for hair colour from his parents then if one of the pair is a dominant gene - i.e. the 'brown hair gene' then that child will have brown hair whether or not they have a blonde hair gene as well. This means that it is more likely that a child has brown or black hair rather than blonde. Let's look at an example: 2 parents have 2 different allele Blonde/Brown (mother) and Blonde/Brown (father). They will therefore both have black or brown hair as they contain brown allele which mask the blonde allele in their chromosomes because the brown allele is dominant. Let's call the genes they have Bl(m) Br(m) Bl(f) Br(f) where Br=Brown, Bl = Blonde, m = mother and f = father. When they have a child then he will inherit one allele from his mother and one from his father. The possibilities of what he inherits are either 1. Bl(m) Bl(f) or 2. Bl(m) Br(f) or 3. Br(m) Bl(f) or 4. Br(m) Br(f) The only combination that produces a blonde child is the first one where both alleles are blonde. In the other three there exists a brown allele and, because brown alleles are dominant, the child will have brown hair irrespective of the fact that in two of the possibilities there is a blonde allele as well. Therefore there is only a one-in-four chance of parents with mixed genes having a blonde child, but it is still perfectly possible. Going back a generation to grandparents means that if all their grandparents had brown or black hair, then, again, the blonde allele could be lying dormant until the time when it is able to show up when it is matched with another blonde allele so that a brown allele cannot mask its effect. In my own family, my cousin's daughter has bright red hair (another recessive allele) although her parents and grandparents are brown haired. My father was red haired but I have brown. So to find the origin of the red-hair-allele we would have to look further back in out family history to find an ancestor of both my father and my cousin's parents. Asit happens our great great grandfather had red hair - and so he passed this on to the family, only to show up rarely in further generations where it was not masked by a more dominant allele like brown or black hair. Sad to say, many marriages have hit the rocks because of a child being suspiciously born with the same colour hair as the milkman or the husband's best friend... but if the couples had taken a lesson in elementary genetics, I am sure that the divorce courst would have been far less busy.
My mom has blond hair and my dad has brown hair - what color hair will the baby have?
This depends on family. If a grandparent has/had red, brown, or blonde, the baby has potential for any of the three. Same as eye color. Possible genetics from grandparents may pass over and effect the hair and eye color of one's child. For example, one parent has blue eyes and one parent has green eyes. If the green-eyed parent has a mother or father with blue eyes, the baby has a higher potenial for blue eyes.
Do the grandparents have visitation in state of oh?
Grandparents had no legal right of access to their grandchild, and parents had complete authority to grant or deny the privilege of visitation. Ohio has authorized grandparent companionship or visitation rights by statute in three circumstances: (1) when married parents terminate their marriage or separate, (2) when a parent of a child is deceased, and (3) when the child is born to an unmarried woman. In such cases, a court may order reasonable isitation if it is in the best interest of the child.
What color do you have to mix with brown to get green or blue?
Brown is the result of mixing the three primary colours red, blue and yellow. As it is not possible to remove a colour from a mixture it would not be possible to mix anything with brown to get green (a secondary colour resultant from mixing blue and yellow) or blue (a primary colour)
How many generations live in the ghetto apt?
Depending on the size of the apartment, there can be up to three generations living in the same residence: grandparents, parents, and children. Note also that numerous "cousins" may reside on the premises.
