The sixth mutant codon of the beta globin gene causing polymerization of haemoglobin and change in $RBC$ shape is . . . . . . .

Haploids are more suitable for mutation studies than diploids. This is because

The following diagram shows two chromosomes and the letters represent the genes.
Chromosome $1$:

$P$

$Q$

$R$

$S$

$T$

$U$

$V$

$W$

Chromosome $2$:

$E$

$F$

$G$

$H$

Which of the following would result if a translocation occurred between chromosome $1$ and $2$?

What affects the rate of mutation?

Most natural mutations are ..........

If a mutation is not visible in successive generations, it is called .....
