Can a mother and a father both have a dominant gene on the same chromosome pair?

Yes. They both can donate their dominant gene. The genotype has two places, one for the one donated by the mom and one for the dad.

What sex chromosome does a girl obtain from her father?
Both parents will give a girl an X chromosome. The father will give a Y and the mother will give an X to a boy.
Chromosome that has both dominant and recessive gene?
your a**
What does it mean to be a hybrid for a trait that is incompletely dominant?
To be hybrid for a trait that is incomplete dominance means that both the mother and the father passed on a gene that was dominant. For example, If you mother has white hair and your father has black hair and both traits are dominant (WB) you will express a gray phenotype.
Female inheritance patterns cannot be analyzed by simply studying the X chromosome because?
The x chromosome is obtained from both father and mother.
What are the genetic preconditions of Prader-Willi syndrome?
The genetic material must be deleted or altered from the chromosome 15 received from one's father or inherit both copies of chromosome 15 from their mother.
Is the Prader Willi Syndrome carried by males or females?
it is carried by both males and females but technically the cause of it is when chromosome 15 from the father is not passed on. so they child only gets the chromosome from the mother. so is it from the mother or father? it cant be both can it? the father's chromosome dissapears, so the mothers replaces it. it is so confusing. Remember that each parent contributes 1 allele, or copy of a chromosome. So in Prader Willi, the mother's allele is imprinted, or silenced and so you're depending on the father's allele for expression. But unfortunately, in PW you get deletion of the father's allele, which is why disease occurs. So yes- can occur in both males and females bc we're not talking about sex chromosomes here.
What is the condition that is carried on the x chromosome whereby an affected mother passes the condition to all sons?
for son x chromosome comes from mother and y chromosome from father. If the mother had both allele got affected then the transfer of disease is 100 %. If only one allele is affected then 50% possibility of son getting affected
What type of DNA do daughters inherit from both parents but sons only inherit from mothers?
Daughters inherit an X-chromosome from each parent but sons receive an X-chromosome only from the mother. The father supplies a Y-chromosome to make the child a boy.
Can a child w a- blood type have a father with a plus and a mother w O plus?
Yes A is dominant over O so if a child inherited the A gene from the father the child would be A Plus (or Rh +) is dominant over Negative (or Rh -). So if mother and father are both heterozygous for the Rh gene then 1 in 4 children will be Negative
For blood groups is it possible for an A positive mother and a B positive father to have an O positive daughter?
Yes, it is possible for an A positive mother and a B positive father to have an O positive daughter. Both A (written as IA) and B (written as IB) alleles (versions of the gene) are dominant over the O (written as i) allele. Therefore the mother could have the alleles IAi, and the father IBi If the daughter receives the i allele from both parents, she will have O type blood. Rhesus positive is dominant, so as long as one of the parents passes on a dominant allele, the daughter will also be positive.
In Jacob syndrome did the nondisjunction occur in the mother or father?
Jacob syndrome, 49XYY, has to occur as a result of nondisjunction in the father. The Jacob Syndrome male would have received the X chromosome from his mother, and both Y chromosomes from the father (since the Y chromosomes can not possibly have come from the mother). Jacob Syndrome can be the result of nondisjunction in meiosis.
What are chromosomes that contain genes which code for the same traits?
Yes they do, but these genes may be both dominant, both recessive or one dominant and its counterpart on another chromosome recessive.
