Understanding Monohybrid Crosses in Genetics

Learn about monohybrid crosses in genetics, including definitions and examples for predicting offspring traits.

0 views

An example of a cross in genetics is the monohybrid cross, where two organisms that are heterozygous for a single trait (e.g., Aa x Aa) are bred. This type of cross helps determine the dominant and recessive traits and predicts the possible outcomes for offspring.

FAQs & Answers

  1. What is a monohybrid cross? A monohybrid cross is a genetic cross between two organisms that are heterozygous for a single trait, revealing how traits are inherited.
  2. How does a monohybrid cross help in genetics? It helps predict the probability of offspring having specific traits by illustrating the distribution of dominant and recessive alleles.
  3. What are dominant and recessive traits? Dominant traits are expressed in the phenotype when at least one dominant allele is present, while recessive traits require two recessive alleles to be observed.
  4. Can I visualize a monohybrid cross? Yes, you can use a Punnett square to visualize the genetic combinations from a monohybrid cross.
