Understanding Single Gene Crosses: A Guide to Monohybrid Genetics

Discover what single gene crosses (monohybrid crosses) are and how they impact genetic inheritance.

300 views

Single gene crosses, also known as monohybrid crosses, involve examining the inheritance of a single trait controlled by one gene. By crossing individuals with different alleles for that gene, you can predict the genotype and phenotype ratios of their offspring. This is a fundamental concept in Mendelian genetics. An example is crossing pea plants to study flower color.

FAQs & Answers

  1. What is a single gene cross? A single gene cross, or monohybrid cross, examines the inheritance of one trait controlled by a single gene.
  2. How do single gene crosses work? By crossing individuals with different alleles, you can predict the genotype and phenotype ratios in their offspring.
  3. What is an example of a single gene cross? A common example is crossing pea plants to study traits like flower color.
  4. Why are single gene crosses important? They provide foundational knowledge in genetics, explaining how traits are passed from parents to offspring.
