It is a fact that parents pass on their Rh factor to their children. When it is the rare negative factor this can cause issues with pregnacy.It would be wise to do further investigation if you are planning a pregnancy.
Yes. The mother would have to have a heterozygous Rh genotype, so that she could pass on an Rh negative allele to her offspring.
No. If both parents are Rh negative, they are homozygous recessive for the Rh factor and can only pass on recessive alleles to their children, and a positive Rh factor is a dominant trait.
The blood type will be the same as one of the parents or a combination, so A or AB. If the parents both have the same Rh factor (+ or -) the baby will have that factor, else it could also be either. The risky situation at birth is where the baby's Rh factor is not the same as the mother's.
Either. We know the mother is homozygous recessive rh- rh- for rh factor, so she can only pass on an rh negative allele to a child. However, if the father is heterozygous rh+ rh- for rh factor, he could pass on one of those two alleles to a child. If he passes on the rh+ (dominant) allele, the baby would be rh positive. If he passes on the rh- allele, the baby would be rh negative.
The Rh factor is a protein that can be present on the surface of red blood cells. If someone has the Rh factor on their red blood cells, they are considered Rh positive. If they do not have the Rh factor, they are considered Rh negative.
It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -
Yes, erythrocytes (red blood cells) can contain the Rh factor, which is a specific protein on their surface. The presence or absence of the Rh factor distinguishes between Rh-positive and Rh-negative blood types. If an individual has the Rh factor, they are considered Rh-positive; if they lack it, they are Rh-negative. This classification is important in blood transfusions and pregnancy.
The "thing factor" likely refers to the Rh factor, specifically the RhD antigen, which can lead to complications in pregnancies with Rh incompatibility. If an Rh-negative mother carries an Rh-positive baby, her immune system may produce antibodies against the Rh factor, potentially affecting subsequent pregnancies. This can result in conditions such as hemolytic disease of the newborn if not properly managed. It's crucial for Rh-negative women to receive appropriate care during and after pregnancy to prevent these issues.
The rh blood factor was first observed in Rhesus monkeys
No, your Rh factor does not change over time.
There is a 50% that offspring will be Rh negative.
If a woman with O positive blood has a baby with a man who has O negative blood, the child will inherit one O allele from each parent, resulting in an O blood type. The Rh factor of the child could be either positive or negative, depending on the combination of the Rh factors inherited. Since the mother is Rh positive, she can pass on either a positive or negative Rh factor, while the father can only pass on a negative Rh factor. Therefore, the baby could be either O positive or O negative.
