Duchenne and Becker muscular dystrophies (DMD/BMD) are X-linked recessive neuromuscular disorders characterized by progressive irreversible muscle weakness and atrophy that affect both skeletal and cardiac muscles
<h3>What is Duchenne/Becker muscular dystrophy ?</h3>
Both Duchenne and Becker muscular dystrophy are caused by mutations in a protein called dystrophin
In Duchenne muscular dystrophy, functioning dystrophin is completely absent in muscle, while in Becker muscular dystrophy, there is some dystrophin present, although not enough for completely normal muscle function.
it usually affects boys in early childhood; people with the condition will usually only live into their 20s or 30s.

Genetic drift is changes in allele frequencies of a gene pool due to chance or random events. This can occur in large or small populations. Genetic drift causes gene pools of two isolated populations to become dissimilar as some alleles are lost and other are fixed.
Because yellow is more dominant so it’s more common for offsprings to have yellow petals but some of the offsprings will also take some traits of the pink petals so it’s A!
