Vedclass · Answer

(A) Mendel studied $7$ pairs of contrasting traits in pea plants ($Pisum$ $sativum$),which has a diploid chromosome number of $2n = 14$. These $7$ traits are located on different chromosomes or are far apart on the same chromosome,allowing them to assort independently. If the plant had only $12$ chromosomes $(2n = 12)$,the $7$ pairs of traits would have to be located on these $12$ chromosomes. Since there are more traits than chromosome pairs,some of these traits would inevitably be located on the same chromosome. Genes located on the same chromosome show linkage and do not follow the Law of Independent Assortment. Therefore,if Mendel had used such a plant,he would not have been able to discover the Law of Independent Assortment.

Column-$I$	Column-$II$
$a$. Allele	$i$. Two alleles of a gene are identical
$b$. Genotype	$ii$. An individual having two different alleles of a gene
$c$. Homozygous	$iii$. Genetic constitution of an organism
$d$. Heterozygous	$iv$. Alternative forms of a gene

If Mendel had studied $7$ pairs of traits in a plant with $12$ chromosomes instead of $14$,then:
