Inheritance Of One Gene

1. Unprotected sexual contact.
2. Sharing of contaminated needles.

The sequence changes, causing the appearance of a premature stop codon. Translation halts earlier, producing a shorter polypeptide chain.

N/A

Farmers prefer apomictic seeds because: Apomictic seeds do not require repeated hybridisation every year, saving costs. They maintain genetic uniformity, ensuring stable yields.

The pedigree shows characteristics of an autosomal recessive inheritance: The disorder skips generations, indicating it is recessive. Both males and females are equally affected, suggesting it is autosomal. Affected individuals inherit two recessive alleles (one from each parent).
