Which one is the incorrect statement with regard to the importance of pedigree analysis?
Correct answer: A. It confirms that DNA is the carrier of genetic information.
- A. It confirms that DNA is the carrier of genetic information.
- B. It helps to understand whether the trait in question is dominant or recessive.
- C. It confirms that the trait is linked to one of the autosome.
- D. It helps to trace the inheritance of a specific trait
Explanation
Pedigree analysis is a system of analysis following the movement and distribution of certain genetic traits in many generations of a family. Pedigree analysis cannot confirm that DNA is the carrier of genetic information because it is an analysis system. For DNA-based experiments, molecular biology techniques are used.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.

Which idea is depicted by a cross in which the F1 generation resembles both the parents?
If two persons with 'AB' blood group marry and have a sufficiently large number of children, these children could be classified as 'A' blood group: 'AB' blood group: 'B' blood group in 1: 2:1 ratio. The modern technique of protein electrophoresis reveals the presence of both 'A' and 'B' type proteins in 'AB' blood group individuals. This is an example of

F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are the same as 1 : 2 : 1. It represents a case of:
When two unrelated individuals or lines are crossed, the performance of F1 hybrid is often superior to both its parents. This phenomenon is called:
