What percentage of the possible types of offspring had the same phenotype as the parents

∙ 8y agoBoth parent plants had the round seed shape phenotype, as the round seed shape (Capital R) is dominant over the wrinkled shape (lowercase r) in Mendel's observations. This means that both parent plants must have had at least one dominant allele (Capital R) for round seed shape.
The genotype of offspring that do not share the parents' phenotype would depend on the specific genetic makeup of the parents. In cases where the offspring do not exhibit the same phenotype as the parents, it is likely due to inheriting different combinations of alleles that result in a different expression of traits. This could involve the presence of recessive alleles or genetic variations that influence the phenotype differently than expected based on the parents' genotypes.
You will have the dominant phenotype for that trait.
The parents would each have the genotype Ee (heterozygous for earlobe attachment) and the phenotype for hanging earlobes. The child inherited the attached earlobe allele from both parents, resulting in the AA genotype and the phenotype for attached earlobes.
Don't give us the options then!! If one parent had 2 dominant genes then all offspring would have dominant phenotype, the same goes for both parents having dominant genes.
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
What percentage of the possible types of offspring had the same phenotype as the parents
both must be tt or both must be Tt
The same phenotype as both of the parents.

If both parents have the same phenotype, but the offspring did not share that phenotype, then it is likely that the parents have a dominant phenotype, but the offspring has a recessive phenotype, which means that the offpring's genotype would be homozygous recessive, and it's parents' genotypes would be heterozygous. For example, the parents may both have the genotype Bb, which gives them black fur. Approximately 25% of their offspring should have the genotype bb, which gives them the phenotype of white fur.

Parents with the dominant phenotype can have offspring with the recessive phenotype if both parents are heterozygous carriers of the recessive allele. In this case, there is a 25% chance for their offspring to inherit two copies of the recessive allele and display the recessive phenotype.
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.
No, a child cannot be afflicted with a dominant trait if both parents have a normal phenotype. This is because dominant traits require at least one copy of the dominant allele to be expressed, and if both parents have a normal phenotype, they would not carry the dominant allele to pass onto their child.
You will have the dominant phenotype for that trait.
