What is the genotype of a child if the mother is homozygous for the dominant trait and the father is homozygous for the recessive trait?

The dominant parent is most likely homozygous dominant, and the recessive parent has only the homozygous genotype. So the dominant parent can pass on only dominant alleles for this trait, and the recessive parent can pass on only recessive alleles for this trait. So all of the offspring would be heterozygous and have the dominant phenotype.

∙ 9y agoBased on Mendelâ??s law of segregation, allele pairs separate during gamete formation. In this case, the child will be heterozygous for the dominant trait.

A mother that is heterozygous for a trait and a father who is homozygous recessive for the same trait have offspring Use this information to complete the matching below Enter the letter of the item?
A. Offspring with heterozygous genotype 100 percent B. Offspring with homozygous dominant genotype 0 percent C. Offspring with at least one copy of recessive gene 50 percent
Which term describes the example below- A child with no freckles has a mother who has freckles and is heterozygous and a father who has no freckles and is homozygous recessive?
We'llsay F is dominant for freckles and f is recessive for non-freckled. The father is ff The mother is Ff The child is ff. Probability of this cross producing a homozygous recessive child is 50%. There isn't a precise term for this cross.
If face shape is recessive allele for mother and a dominant allele for father is it a genotype or phenotype?
Both. A genotype is the scientific part, the lettering. For example; Lets say the mother's face shape, being recessive, is represented by lower case (s), and the father's, being dominate, is represented by captial (S). So the genotype for this sidtuation is Ss The phenotype is the physical appearance of the trait.
If the mother is O positive and father is AB negative what type will baby have?
The O blood type is always recessive; A and B are codominant and dominant to O. The O blood type is represented with both O alleles, and the AB blood type is represented with one A and one B alleles. The child will either have a genotype AO or BO, but the blood type will be expressed as A or B. This cross can be demonstrated easily with a Punnett square. For the Rh factor. This is dependent on the mother's genotype since the father carries the recessive alleles. The Rh factor for both homozygous and heterozygous dominant cases is positive. Thus, if the mother is heterozygous there's a 25% chance that her child with have be Rh+. If she is homozygous dominant, her children will always be Rh+. This can also be demonstrated with the Punnett Square.And that is the answer
In a punnet square where the mothers genotype is Dd and the fathers genotype is dd does the mother or the father have dimples?
The mothers will because the father is the dominant.
A trait that is masked by a dominant trait is called?
DNAactually it is not DNA at all, a dominant trait, masks a recessive trait.
Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.

What are the two different alleles for a gene?
I think it is Dominant and recessive.
What is the child's genotype if parents both have normal arches produce a child with flat feet?
Child's genotype would be homozygous recessive alleles (nn) and parents would both have heterozygous dominant alleles (Nn).
What is the color of the baby eyes if the mother have the recessive gene for blue and the father has blue eyes?
I assume you mean the mother has a dominant allele for some other color. Father is homozygous recessive for blue. Dominant allele + recessive blue X recessive blue + recessive blue The baby has a 50% chance of blue eyes and a 50% chance of getting the dominant colored eyes.
Can a blood type O father give blood type A to his offspring?
It depends on the mother's genotype. O blood is recessive, so the father has OO blood. Both A and B are dominant, so an AA or AO genotype would result in a type A blood phenotype. Since the father is homozygous recessive, he must donate an O. Therefore, for the child to be type A, the mother must donate an A to create an AO genotype for the child. So, if the mother has type A blood or type AB blood, the child could have type A blood.
What is meant by dominance and recessiveness?
First of all alleles code for different traits all across an organism. Simply looking at it, a dominant allele is a trait that essentially "dominates" or is expressed over a recessive allele. In theory every organism (that is not asexual) receives one allele from its father and one allele from its mother. If both of these alleles are dominant (homozygous dominant) than the dominant trait is expressed, if one is dominant and one is recessive (heterozygous) than still the dominant trait is expressed. However, if the alleles for both traits are recessive (homozygous recessive) than the recessive trait will be expressed.

How do you xxplain how the hitchhicker's thumb trait is determined using the following words allele domnate recessive homozygous heterozygous?
basically, the hitchhiker's thumb is a physical characteristic that is inherited from your mother and/or father. when you were conceived, your mother gave you some of her genes, and your father gave you some of his. the hitchhiker's thumb is either a dominent or recessive trait. It if is dominant, you could have a heterozygous parent and still have a 100% chance of inheriting it. If the hitchhiker's thumb is recessive, you must have both of you parents homozygous for the gene to have a 100% chance of inheriting it. The alleles are either HH (homozygous dominant), Hh (heterozygous), or hh (homozygous recessive). H H << if the thumb is dominant trait, you have a 100% chance of getting it H HH HH << if the thumb is recessive trait, you have a 0% chance of getting it h Hh Hh
Having freckles is dominant (F) and not having freckles is recessive (f). A mother has Ff and a father has ff. If they have a child which genotype will make their child not have freckles?
ff (apex)
