Consider the following statements.
i. Mendel is called the father of genetics.
ii. Law of segregation states that each gamete receives two alleles for a trait.
iii. In a monohybrid cross, F2 phenotypic ratio is 3:1.
iv. Law of independent assortment works only for traits on different chromosomes.
Select the group of correct statements only:

Correct option is D

The correct answer is (d)  i, iii and iv
Explanation: •  Statement i is correct:  Gregor Mendel is known as the  Father of Genetics for his foundational work on the laws of inheritance using pea plants. •  Statement ii is incorrect: The  Law of Segregation states that during gamete formation, the two alleles for a trait segregate (separate) so that each gamete receives  only one allele, not two. •  Statement iii is correct: In a classic Mendelian  monohybrid cross (e.g., Tall x Dwarf), the  F2 generation shows a  phenotypic ratio of 3:1 (3 dominant: 1 recessive). •  Statement iv is correct: The  Law of Independent Assortment applies to genes located on  different chromosomes (or very far apart on the same chromosome). If genes are close together on the same chromosome, they show  linkage and do not assort independently.
Information Booster: • The  genotypic ratio of a monohybrid cross in the F2 generation is  1:2:1 (1 Homozygous Dominant : 2 Heterozygous : 1 Homozygous Recessive). • Mendel’s work was based on seven pairs of contrasting traits in  Pisum sativum, which luckily were either on different chromosomes or behaved as if they were.
Additional Knowledge: Law of Segregation (Statement ii) • This is also known as the  Law of Purity of Gametes because a gamete always carries only one member of an allelic pair and is therefore "pure" for that trait.
Law of Independent Assortment (Statement iv) • This law is observed during a  dihybrid cross, where the F2 phenotypic ratio is  9:3:3:1. • The physical basis for this law is the random orientation of homologous chromosome pairs during  metaphase I of meiosis.
