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.

What is the result of a cross between homozygous red and homozygous whitw four o'clock flowers?
Red color being governed by a dominant gene, all offsprings from this cross will have red flowers.
How does codominance change the offsprings phenotype?
Codominance is when both alleles of a gene are fully expressed, resulting in a phenotype that shows traits from both alleles. This can lead to a different phenotype than observed with simple dominant-recessive inheritance, as both alleles contribute equally to the offspring's appearance.
How can all offsprings from two parents be tall?
Heterozygoes dominant or Homozygoes dominant.
What is the phenotype of a heterozygous four o'clock flowers?
White-flowered, red-flowered, and pink-flowered.
Do all heterozygous pairs of allele produce an intermediate phenotype?
No
Is it possible for two alleles to produce four phenotype?
yes
What is the phenotype of a hetozygous four o clock flower?
R'R'
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
What is the result of a cross between homozygous red and homozygous whitw four o'clock flowers?
Red color being governed by a dominant gene, all offsprings from this cross will have red flowers.
How do dominant and recessive alleles affect pheno type?
Dominant alleles are always expressed in the phenotype when present, masking the expression of recessive alleles. Recessive alleles are only expressed in the phenotype when two copies are present. This results in a wide range of phenotypic variations depending on the combination of alleles present in an individual.
How does codominance change the offsprings phenotype?
Codominance is when both alleles of a gene are fully expressed, resulting in a phenotype that shows traits from both alleles. This can lead to a different phenotype than observed with simple dominant-recessive inheritance, as both alleles contribute equally to the offspring's appearance.
In sweet pea plant R is the allele for red flowers and r is the allele for white flowers a. If an RR plant and an rr plant are crossed what will be the outcome of their offsprings?
All the offspring will have red flowers because the trait for red flowers is dominant (R) over the trait for white flowers (r). The offspring will all be heterozygous (Rr) for flower color.
How many offsprings do dolphind usually have?
how many offsprings do dolphins usually have
What is the number of Offsprings a rabbit is expected to have?
2 through 12 offsprings
How can all offsprings from two parents be tall?
Heterozygoes dominant or Homozygoes dominant.
To produce pea plat that only display the recessive phenitypw of a trait what must be the genotypes of the parent plats?
To produce offspring that only display the recessive phenotype of a trait, both parent plants must be homozygous recessive for that trait. This means both parents would have the genotype of aa for that specific trait.
What are an individual's observable traits called?
genotype or phenotype
