The observable traits or characteristics of an organism, for example hair color, weight, or the presence or absence of a disease. Phenotypic traits are not necessarily genetic.

What is A pattern of inheritance in which neither allele is phenotypically dominant to the other?
incomplete dominance
How many phenotypically different types of offspring are possible in a dihybrid cross between two heterozygous individuals?
3
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
What is the phenotype of all four offspring's?
Generally, if the parents are heterozygous and one allele is dominant over the other there are only 2 phenotypes and 3 genotypes. Parents Aa can produce AA, Aa and aa offspring. If the heterozygous individuals have an intermediate phenotype, then three genotypes and 3 phenotypes are possible. If 2 traits are being studied using heterozygous parents AaBb then the possible Genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBb, aaBB, aabb which is nine genotypes. But there are 4 phenotypes. AABB AABb AaBB AaBb are phenotypically the same. aaBb, aaBB are phenotypically the same. Aabb, AAbb are phenotypically the same. aabb
What is the phenotype ratio for a recessive trait in Mendels F2 generation?
Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.
What is phenotypically xy on ultra sound?
Xy is a boy
A male with a missing SRY gene would be phenotypically?
female
What is A pattern of inheritance in which neither allele is phenotypically dominant to the other?
incomplete dominance
What is the task of the animal breeder?
to produce the animal that is both phenotypically and genotypically demanded by the customer.
Who generally inherits sex-linked traits?
In humans there is a higher incidence of male children who phenotypically diplay a sex-linked trait. The inheritence level in females is about equal to that of the males but, because they have two X chromosomes they carry it genotypically but not phenotypically.
What is incomplete penetrance?
Referring to the presence of a gene that is not phenotypically expressed in all members of a family with the gene.
The evolutionary history of a species is it's?
Phenotypically expressed and influenced Genotype: in other words, it's appearance.
How many phenotypically different types of offspring are possible in a dihybrid cross between two heterozygous individuals?
3
Is an allele that produces a trait in the heterozygous condition recessive?
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
What is the phenotype of a heterozygous individual what is the genotype of a heterozygous individual?
Bb The phenotype is what the individual looks like. The genotype is the genetic material at the site that can be passed on even if it isn't expressed. For example: Animal with black hair bb (can only pass the black characteristic on to it's offspring because it is homozygous recessive). It is phenotypically black. An animal with red hair can be Bb or BB. Bb is heterozygous and the animal is phenotypically red. BB is homozygous dominant for red and the animal is phenotypically red. More information than requested but an explanation none the less.
A human individual is phenotypically female but her interphase somatic nuclei do not show the presence of Barr bodies what concerning her is probably true?
female
