Starch synthesis in pea : Multiple alleles

Vedclass · Answer

(A) $1$. Starch synthesis in pea is controlled by a single gene with two alleles ($B$ and $b$), which exhibits pleiotropy, not multiple alleles.$2$. $T. H. Morgan$ is known for his work on linkage in Drosophila.$3$. $XO$ type sex determination is observed in grasshoppers.$4$. $ABO$ blood grouping in humans is an example of multiple alleles and co-dominance (for $I^A$ and $I^B$ alleles). However, the primary genetic principle for $ABO$ blood grouping is multiple alleles, and the pairing with co-dominance is technically correct but less specific than the error in option $A$. Since starch synthesis is clearly pleiotropy, option $A$ is the $wrongly$ matched pair.

List $I$	List $II$
$A$. Two or more alternative forms of a gene	$I$. Backcross
$B$. Cross of $F_1$ progeny with homozygous recessive parents	$II$. Ploidy
$C$. Cross of $F_1$ progeny with any of the parents	$III$. Allele
$D$. Number of chromosome sets in plant	$IV$. Test cross

Which of the following pairs is $wrongly$ matched?
