HOLLA peoples. Today we handed in our papers about genetics and meiosis. If you havent handed your's in yet, then get it in as soon as possible.


Mr. Finley gave us some vocabulary terms and we had to come up with definitioins. This is what the five guys came up with.


Dominant An allele that needs only one of its type in a homologous pair in order for that gene to be shown in the phenotype.


Recessive An allele that needs two of it type in the homologus pair in order for it to be shown in the phenotype.


Phenotype are the genes that can be observed from the outside.


Genotype all the genes inside and outside that you have but can't see.


When we compare this to the pea soup experiment, we can say...... (look to picture above)
This is because, phenotype is what you can see and you can see the peas texture and color but you can't see its genotype or the homologous pairs in this case. The reason that yellow is dominant is because the probability of getting it is higher. There is a 3/4 chance of getting at least 1 capital Y and a 1/4 chance of getting two lowercase Y's. this is also why green is recessive. There is less of a chance of getting it. The same goes for wrinkled and smooth peas just using R's.

For the rest of class, we discussed the answers to these questions and how they related to the pea soup experiment.

Unfortunately time flew when we were having fun and the period quickly came to a close
