Distinguish between the following paired terms:
(b) heterozygous and homozygous,
검증된 단계별 안내1
Step 1: Understand that both terms, heterozygous and homozygous, relate to the genetic makeup (genotype) of an organism at a specific gene locus.
Step 2: Define homozygous as having two identical alleles for a particular gene. This means both copies of the gene inherited from each parent are the same (e.g., AA or aa).
Step 3: Define heterozygous as having two different alleles for a particular gene. This means the two gene copies inherited from each parent differ (e.g., Aa).
Step 4: Recognize that these differences in alleles can affect the organism's traits (phenotype), depending on whether the alleles are dominant or recessive.
Step 5: Summarize by contrasting the two: homozygous means identical alleles at a gene locus, while heterozygous means different alleles at that locus.

주요 개념
질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Homozygous
Homozygous refers to having two identical alleles for a specific gene on both homologous chromosomes. This means the organism inherits the same version of a gene from each parent, resulting in a uniform genetic expression for that trait.

Genotype & Phenotype
Heterozygous
Heterozygous describes having two different alleles for a particular gene on homologous chromosomes. This genetic variation can lead to dominant-recessive interactions, where one allele may mask the expression of the other.

Alleles and Gene Expression
Alleles are different forms of a gene that determine specific traits. Understanding how alleles interact—whether identical or different—is essential to grasping the concepts of homozygosity and heterozygosity, as these interactions influence an organism's phenotype.
