Can anybody explain to me the triplet code for Biology as ? I don't get it
The triplet code is the 3 digit code that makes up/codes for a specific amino acid or a stop codon! It is a degenerate code meaning that one triplet code could code for two or three amino acids and so therefore if one code is changed in a mutation, it might be a neutral mutation as the triplet code its mutated to might code for the same amino acid. For example UAG codes for a stop codon and say AUU codes for an specific amino acid ( eg: lysine, methionine etccc) The triplet codes are then translated into amino acids which are brought to the ribosome by tRNA which is when the protein is made in protein synthesis!
Hope this helps
If you understand genetics by any chance i could really use some help on that!!?

Good post, I'd say, especially that point about neutral mutation. Btw, what do you need help with in genetics?
haha aw thankyouuu
okay so i dont get the genetic diagrams and how to work out phenotype ratios and to do cross squares to explain certain values of offspring in an F1 generation? also i dont understand where and how you would use codominance in crossing squares!
sorry i know thats a lot....i basically struggle with the whole thing but those are the worst; genetic diagrams!! thankyou so much in advance if you can help!!!

Basically say you have two red heterozygous flowers, with white as a the recessive colour. This means you have to plants with the genotype Rr (R=Red, r=White)
I've written it out for you here:
Is this what you need help with or have I gone completely down the wrong track.
FYI I made an error that I only just noticed. Rather than Rr being spotted it should be pink. Sorry! hope that hasn't confused you.

Thankyou so much!!!!!!!!!!!
okay so codominace is the one where both alleles will contribute to it whereas the one you did above; the phenotype is only controlled by the dominant allele...is that right?
how do you predict phenotypic ratios and use them to solve problems invovling epistasis?

No problem
Basically codominance is where they have equal dominance - so white and red both have the same dominance, so when both are present in the genotype, then they both must be present in the phenotype as well.
This could be a blend of the two (which is called incomplete dominance) or it could be where the animal has spots or patches of both colours.
So both of the alleles contribute to the phenotype.

I'm sorry I've never done epistasis. I kind of know what it is but I don't know how to predict the phenotypic ratios. Sorry!

The other person might be able to help you there!
Thankyou so much you've been a wonderful help! xoxo
