검증된 단계별 안내1
Understand the definition of homologous chromosomes: Homologous chromosomes are pairs of chromosomes in a diploid organism that have the same structure and carry the same genes at the same loci, but they may have different alleles.
Consider the inheritance of homologous chromosomes: In sexually reproducing organisms, one chromosome of each homologous pair is inherited from each parent, not from the same parent.
Evaluate the presence of homologous chromosomes in cell types: Homologous chromosomes are found in eukaryotic cells, not prokaryotic cells, as prokaryotes typically have a single circular chromosome.
Analyze the genetic content of homologous chromosomes: While homologous chromosomes carry the same genes, they are not identical copies because they can have different alleles for those genes.
Review the provided statements and identify the correct one: The statement 'Homologous chromosomes carry the same genes but may have different alleles' accurately describes homologous chromosomes.
