RafaCross breeding involves mating two unrelated individuals from different breeds or populations to produce offspring with a mix of traits. Inbreeding involves mating individuals that are closely related, such as siblings or parent-offspring, which can lead to an increase in genetic defects or expression of negative traits due to the lack of genetic variation.

What is the difference between a cross section and a transverse section in anatomy?
A cross section in anatomy is a cut made across the body or an organ, showing its internal structure. A transverse section is a specific type of cross section that is made perpendicular to the long axis of the body or organ.
Describe the difference between a true-breeding individual and a hybrid?
A true-breeding individual consistently produces offspring with the same traits as the parent when self-pollinated or crossed with another true-breeding individual. In contrast, a hybrid is the result of crossing two genetically different parents and exhibits a combination of traits from each parent.
Explain the difference between self-pollination and cross-pollination?
Self-pollination is the inbreeding process occurring in between two flowers of the same plants, in this pollens are transferred from the anthers to the stigma. Cross-pollination is the outbreeding process between the two plants of the same species and of different flowers, in this also the pollens are transfers from the anthers to the stigma.
What is pure breeding?
Pure breeding refers to the practice of mating individuals within the same breed that consistently produce offspring with the same desired traits. This method helps maintain the characteristics of a specific breed or line over generations through selective breeding. Pure breeding is often used in agriculture and animal husbandry to standardize traits such as size, color, or productivity.
What is the difference between a monohybrid and dihybird cross?
A monohybrid cross involves the study of one trait or gene, whereas a dihybrid cross involves the study of two traits or genes simultaneously. In a monohybrid cross, only one pair of alleles is considered, while in a dihybrid cross, two pairs of alleles are considered.
