Not necessarily. When you do the dihybrid cross, The results are:
* 56.25% A positive * 18.75% A negative * 18.75% O positive * 6.25% O negative However, this is only when both parents are both A positive heterogeneously.
When dihybrid cross is done for parents that both have A positive but only one of them is heterogeneous, the result is:
* 100% A positive (with 68.75% being heterogeneous) When dihybrid cross is done for parents when both have homogeneous A positive, the result is:
* 100% A positive( no heterogeneous)
What else can I help you with?
Can a child with b negative blood have parents with o positive?
Only if he's adopted. Parents with a + blood type can have children with a - blood type, but parents with an O bloodtypes can only have O type children together.
Can parents with b negative blood have a child with o positive blood?
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
Can parents have negative and positive Rh children?
CAN children hae positive and negative RH factor blood types
What is the chance of both parents 0 positive having three children O positive and one A positive?
Assuming both parents are O positive (OO), they can only pass on the O allele. However, since one child is A positive, it means that one parent has the A allele (AO). This scenario is not possible with two O positive parents genetically. Therefore, the chance of both O positive parents having three O positive children and one A positive child is not genetically feasible.
Can parents have both B Rh positive and A1 Rh positive children?
Yes
Can o positive and o positive make a B negative or b positive?
No - if both parents have blood type O, then the only possibility for their children is also blood type O. If they are both heterozygous for Rh (+/-) then they could have either + or - children. If either of them are homozygous (Rh+Rh+) then all the children will be +.
Will parents with a positive blood type have children with a positive blood type?
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
How do social workers use positive reinforcement?
Social workers use positive reinforcement to get parents to do what they need to do for their children. Instead of taking children away from parents, they help them learn how to care for them.
Can a baby be born with positive blood if both parents are negative?
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.
Mother o positive father o positive and child also o positive is possible or not?
Yes, it is possible. Parents who are O positive may have children who are O+ or O-, depending on the parents' genotypes.
How can parents encourage and reinforce good behavior in their children to help them earn a star for their positive actions?
Parents can encourage and reinforce good behavior in their children by setting clear expectations, providing positive reinforcement, and offering rewards for positive actions. This can help children understand the benefits of good behavior and motivate them to earn a star for their positive actions.
What did Rogers believe was important for parents to do?
provide unconditional positive regard for their children
