Document Summary
The tetrad is the four spores of a yeast, produced after meiosis. Under appropriate environmental conditions, diploids sporulate and undergo meiosis. The meiotic products, spores, remain packaged in the parental cell body to produce the tetrad. A tetrad type containing two different genotypes, both of which are parental. A tetrad type containing two different genotypes, both of which are recombinant. Contains 2 parental +2 different genotypes, both of which are recombinants. If pd>>>npd, it is likely to be linked. If pd=npd, it is likely that the loci aren"t linked. Wouldn"t be able to know if it is a no crossing over or double crossing over. Wouldn"t be able to know if it is a single or double crossing over. The only one result that we can tell it is a double cross over event. These 3 happen in a ratio of 1:2:1. Crossing over occurs at the 4 strains stage. Prove that crossing over occurs after dna synthesis.
