Can a family have the same genotype?
Most cells are diploid, which means that they have two copies of each chromosome. One comes from your mother, and the other — from your father, which adds up to a total of 46 chromosomes. … X and Y chromosome differences mean that brothers and sisters can never have identical genotypes.
Can two as genotype marry each other?
However, AS and AS should not marry because there is every chance of having a child with Sickle Cell Disease, while AS and SS shouldn’t think of marrying. And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
What does it mean to have the same genotype?
The genotype of an organism is its complete set of genetic material. … If both alleles are the same, the genotype is referred to as homozygous. If the alleles are different, the genotype is referred to as heterozygous.
Can two O positive parents have an A positive child?
Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations. How does this happen?
Can a child have different blood group than parents?
Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.
What is the sickness of AA genotype?
BUT IS THERE REALLY AN AA SICKNESS? Studies have shown that those with the AA genotype are more susceptible to malaria. One study involving 372 children at the University of Uyo Teaching Hospital found that “children with genotype AA (92.3%) were more susceptible to malaria parasite than AS (5.1%) and SS (2.6%)”.
Can a genotype change?
Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.
Can AA and SS marry?
AC is rare whereas AS and AC are abnormal. Compatible genotypes for marriage are: AA marries an AA. … And definitely, SS and SS must not marry since there’s absolutely no chance of escaping having a child with the sickle cell disease.
Does as genotype fall sick?
Sickle cell trait (AS) usually does not cause any health problems.
Is AA genotype the strongest?
The AA genotype has the best compatibility ratio. An individual with the AA genotype can choose a life partner from virtually all other genotype categories with an extremely minimal possibility of sickle-celled offspring.
Which blood group is the best?
Type O negative
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there’s a limited supply of the exact matching blood type. That’s because type O negative blood cells don’t have antibodies to A, B or Rh antigens.
Can a+ have babies?
An A+ parent and an O+ parent can definitely have an O- child.
What foods should blood type A avoid?
Those with type A blood should choose fruit, vegetables, tofu, seafood, turkey, and whole grains but avoid meat. For weight loss, seafood, vegetables, pineapple, olive oil, and soy are best; dairy, wheat, corn, and kidney beans should be avoided.
Which blood group should not marry?
This is mediated by the antigen-antibodies reaction. Transfer of maternal antibodies across the placenta occurs. This happens when Rh +ve man marries Rh-ve lady. So Rh +ve man should try to avoid marrying Rh-ve lady.
