What Happens When Two Dominant Genes Cross in Genetics?

Discover the fascinating results when two dominant genes cross, leading to unique genetic traits in offspring.

96 views

When two dominant genes cross, the offspring can exhibit the traits of both dominant genes. This type of genetic situation often results in a phenotype expressing the dominant trait, assuming simple inheritance patterns. If both genes are for distinct characteristics, both traits will co-appear.

FAQs & Answers

  1. What are dominant and recessive genes? Dominant genes are those that express their traits even when only one copy is present, while recessive genes require two copies to manifest their traits.
  2. How can I predict traits in offspring? You can predict traits using Punnett squares to visualize combinations of genes from each parent.
  3. What is a phenotype? A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genetic makeup.
  4. What role do genes play in inheritance? Genes carry the hereditary information that determines traits, and their combinations from parents influence the characteristics of the offspring.
