- A rare genetic disorder resulting from homozygosity for a recessive allele (\( r \)) occurs in 2 out of every 10,000 individuals in a population. Assuming that (i) the disorder is not lethal, (ii) the disorder does not impact reproductive success, (iii) no new mutations are introduced in the population, and (iv) the population follows Hardy-Weinberg equilibrium, the percentage (%) of the carriers in the population that pass the \( r \) allele to offspring is .......... (rounded off to 1 decimal)
- A cDNA was synthesized from the mRNA of a eukaryotic gene. After cloning and sequence analysis, the double-stranded cDNA of 614 bp revealed 125 bp 5'-UTR and 120 bp 3'-UTR. The number of amino acids present in the polypeptide encoded by this gene is ............... (answer in integer)
- In a plant species, the genotype \( DDEE \) is crossed with the genotype \( ddee \); and the F1 is test crossed. Considering that the two genes are linked and 20 map unit (cM) apart in the chromosome, the percentage (%) of the test cross progeny with the genotype \( ddee \) is ........................ (answer in integer)
