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.

What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
Do Parents with the dominant phenotype cannot have offspring with the recessive phenotypeous for a trait that is?
No. Parents with the dominant phenotype might be heterozygous in their genotype. This means they could carry both the dominant and recessive allele for a trait. So they could both pass the recessive allele to an offspring, who would then have the homozygous recessive genotype and recessive phenotype.
If about 50 percent of the offspring have the dominant phenotype and 50 percent have the recessive phenotype what are the genotype of the parents?
If the phenotype is recessive then the genotype must be dd.
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
Why do we call some alleles dominant?
because it dominates the phenotype

If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.

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 is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
Can two organisms have the same phenotype and a different genotype?
Yes,if one has two dominant alleles and other has a dominant and a recessive allele
When is a recessive allel expressed in offspring?
A recessive phenotype is expressed in an offspring that has a homozygous recessive genotype for that trait.
A man has one recessive allele and one dominant allele. what is his phenotype?
He would have the recessive phenotype for that trait.
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
A homozygous dominant genotype means that both alleles for a trait are dominant. A heterozygous genotype means that one allele is dominant and the other is recessive. A heterozygous genotype will express the dominant phenotype, not the recessive phenotype.
