Explore the concept of crossing in biology and its role in genetics and breeding.

351 views

Crossing in biology refers to the process of breeding two different individuals to study their genetic traits. This method is used to understand how traits are inherited and to create organisms with desired characteristics, often seen in plant and animal breeding. By observing the offspring, scientists can deduce information about genes, dominance, and variation.

FAQs & Answers

  1. How does crossing affect genetic variation? Crossing introduces new combinations of genes in the offspring, leading to greater genetic diversity and potential new traits.
  2. What is the purpose of crossing in breeding? The purpose of crossing is to combine desirable traits from two parents to breed offspring that exhibit those characteristics.
  3. What are dominant and recessive traits? Dominant traits are expressed in the phenotype even if only one allele is present, while recessive traits require two alleles to be expressed.
  4. Can crossing be used in plants? Yes, crossing is widely used in plant breeding to create new varieties with specific traits, such as disease resistance or improved yield.
