meiome and genome

I thought eukaryote genetic inheritance came simply from the adding together of (recombinant) haploid chromosomes in the new zygote. But there is a lot of RNA involved? A crowd of unique proteins and mRNA in addition to the chromosomes ...

Re: Muscular dystrophy inheritance question

Right - this is autosomal, therefore it is not Duchenne muscular dystrophy (DMD) and is not a mutation of the dystrophin gene. Thanks, I had missed that. The upper sequences look identical, while the lower sequences show two different sequences for the female (due to the N position, which shows two ...

Re: Muscular dystrophy inheritance question

... and 1 wildtype (lower sequence) and is therefore unaffected as it is recessive. I am not sure if muscular dystrophy actually shows this type of inheritance or if my lecturer made that up, but based on the fact that we were told it's autosomal recessive I'm guessing the woman must have 2 mutations ...

Re: Muscular dystrophy inheritance question

The lower sequence shows one trace for the male but for the female there are two traces at one nucleotide position (labelled N). That looks like the allelic difference; since the female has two copies of the dystrophin gene that differ slightly, this can give rise to the two traces in the sequence (...
