Re: Year 11 Meiosis helpp!!!

During the first part of meiosis (prophase 1) there can be recombination (crossover) of homologous chromosomes. This would show up on your diagram as being a little bit of red on one arm of the blue X, and a matching little bit of blue in the same place of the ...

Re: Genes in the same linkage group are inherited together?

A centimorgan is the distance between two loci where the frequency of a crossover between the two loci per generation is 0.01. So the frequency of crossover between two genes 1.5 cM apart will be 0.015, and the frequency of a crossover between genes 140 cM apart ...

Re: Genetics Hard problem!

... 1 percent.) I scanned the whole passage in the attachment. Answer is 34 m.u. This is what I did: B+/ba x ba/ba (parental strands) If there is no crossover, B+/ba (black), ba/ba (white) If there is one crossover (between the sister chromatids), BA/ba (albino), b+/ba (brown) So in the crossover, ...

How are balancer chromosomes introduced?

... from homozygotes of stock B die. How does this happen? The time difference must be a factor, I imagine. Also, the TM2 balancer has a double crossover region near the smg gene.
