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.

Column-$I$	Column-$II$
$(A)$ Dominance	$(i)$ Many genes govern a single character
$(B)$ Codominance	$(ii)$ In a heterozygous organism only one allele expresses itself
$(C)$ Pleiotropy	$(iii)$ In a heterozygous organism both alleles express themselves fully
$(D)$ Polygenic inheritance	$(iv)$ $A$ single gene influences many characters

Column $I$	Column $II$
$(a)$ Sickle cell anaemia	$(p)$ Homogentisic acid
$(b)$ Alkaptonuria	$(q)$ Lack of Melanin
$(c)$ Albinism	$(r)$ Accumulation of Amino acid
$(d)$ Phenylketonuria	$(s)$ Defective haemoglobin

Which of the following pairs is $wrongly$ matched?
