In dogs wire hair (D) is dominant over smooth hair (d) . If two wire haired dogs produce a smooth haired pup , the genotypes of the parent?
Shante Monae
Both parents are Dd. They express the dominant gene but carry the recessive one, so there's a 25% chance that the pup will express the recessive one. If either parent was DD, then it would be impossible to produce a pup that expresses the recessive gene.

A homozygous dominant parent will produce a gamete with?
They will produce gametes that are also homozygous.
What percentage of genotypes would most likely be found in the f1 generation offspring?
If the parent generation consisted of a homozygous dominant parent and a homozygous recessive parent, then the F1 generation would be 100% heterozygous.
What category of Can make and produce fertile offspring?
dominant parent traits.
If yellow peas are dominant over green peas the offspring of a pure dominant and a pure recessive cross is?
Let Y represent the dominant allele, and yrepresent the recessive allele. Let us also assume that "pure" means homozygous for that trait ("pure' is not the usual term for this, "homozygous" is) So, the two genotypes of the parents of the cross are: Parent 1: YY Parent 2: yy To solve a problem like this, one always has to determine what kind(s) of gametes each parent can produce. Both parents are homozygous for their respective traits, so in this case, each parent can only produce one kind of gamete: Parent 1 can only produce Ygametes, and Parent 2 can only produce y gametes. Therefore, every one of their offspring will have the following genotype: Yy Since every one of the offspring of the cross carries a Y allele, and Y is dominant, all of the offspring will be yellow.
What category of organisms can make and produce fertile offspring?
dominant parent traits.
What does dominant means?
Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?

What are the genotypes of the parents in the monohybrid cross below if the following offspring genotypes are predicted?
The offspring in the first column both have two dominant T alleles. Therefore, you know that the father (parent on the left hand side) is TT and the mother (parent on the top) has a dominant T in that column too. The offspring in the second column are Tt. The dominant T came from the father, as figured out in the first part of the problem. The recessive allele t came from mother's second empty box.
Freckles are a dominant characteristic The appearance of freckles is the phenotype what represents a heterozygous genotype for freckles?
If all of the children have freckles, that means that both parents had dominant genotypes. (Mother; FF and Father; FF). Or, one parent could have a hybrid genotype. (For example, Mother; Ff and Father; FF). Based on the outcome of a Punnett Square, either one parent must have a hybrid and the other dominant, or both must have dominant genotypes.
How much do the expected genotypes of 100 offspring with the observed genotypes disagree?
I it AA in both parent
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.
To produce pea plants that only display the recessive phenotype of trait what must be genotypes of the parent plant?
both must be tt or both must be Tt
