Answer:
1.)
Parent 1:
Ff (genotype) and free earlobes (phenotype)
Parent 2:
ff (genotype) and attached earlobes (phenotype)
2.)
Ff and ff (possible genotypes)
Free earlobes and attached earlobes (possible phenotypes)
Step-by-step explanation:
Phenotypes are the observable traits an organism displays.
Genotypes are the genetic sequences organisms' possess that code for particular traits.
I am assuming that heterozygous individuals (Ff) display the dominant trait (free earlobes). As such, one parent has the Ff genotype and the free earlobe phenotype. The other parent has the recessive genotype (ff) and phenotype (attached earlobe).
50% of the children will have the same genotype and phenotype of one parent and the other 50% will have the same genotype and phenotype as the other parent.
None of the children will have the completely dominant genotype (FF).
