Mendel's Laws

[itsMRPHI]

In plain and simple english what is Mendel's laws?

[herzy]

1 - each gamete receives one copy of each gene/chromosome (they are segregated). also, every gamete has a copy of every gene/chromosome!
2 - the different alleles are put in a random combination in each gamete (assorted independently).

[Russ]

Law 1: alleles go to different gametes
Law 2: the alleles from Law 1 do so randomly

[herzy]

Law 1: alleles go to different gametes
Law 2: the alleles from Law 1 do so randomly

more simply put, but its not the alleles that go to different gametes (in law 1), but rather the whole chromosomes (which carry different alleles)

make sure you are all crystal clear on the meanings (and differences) of terms such as chromosome, allele, gene, locus, etc

Very coincidental that I'm writing down the definitions of the laws right this very moment.
Principle of Segregation: Allele pairs separate into gametes so that each gamete carries one allele of each gene.
Principle of Independent Assortment: Alleles of a gene controlling one trait assort independently of alleles of another gene controlling a different trait.

Hmm, those definitions don't sound very good :\

[Russ]

He asked for simple, I gave simple.

My definitions are something like this if you want them

1. Production of gametes results in division of chromosomes so that they are evenly and equally distributed between gametes
2. Genes on different chromosomes, or sufficiently far apart on the same chromosome, segregate randomly with respect to 1

don't worry too much about them, basically you just need to know how to work with them, e.g. mendellian questions such as dihybrid crosses etc.

yeah just doing it cause it appears on multiple choice and thats where im losing my marks
