If an organism has two different alleles for a given trait (like attached and free earlobes), they are considered ____________, and in __________ traits we automatically know the genotype. Dominant Recessive a recessive, homozygous b homozygous, recessive c hybrid, dominant d heterozygous, recessive

Answer 1

The correct answer is d) heterozygous, recessive.

In this context:

• An organism with two different alleles for a trait (like attached and free earlobes) is considered heterozygous.
• For recessive traits, the phenotype (physical expression of the trait) does not reveal the genotype unless both alleles are recessive. Thus, when a trait is recessive, we cannot automatically determine the genotype unless it is showing the recessive phenotype.
