Independent Assortment - continued
Problems of Various Genotypes / Phenotypes
Number of Progeny Required [Refer to n
...
Often in agriculture, people construct pure lines- homozygous
...
Want to make strains that are completely
homozygous
...

2
...

Usually seen in Corn or Maize
...
Every F1 progeny
is completely identical to the other one but are heterozygous and so are
extremely uniform in nature
...
Advantage is high yield of the crop desired
...
Thus, independent assortment would occur
...
Hybrid vigour is thought to shelter the crummy gene
...
Occurs in Meiosis
...

3
...
Independent assortment occurs
due to how bivalents attach and align on the spindle
...
[refer to n
...
2 haploid strains fuse - 2
haploid nuclei fuse together forming a diploid organism (meiocyte) and
immediately goes through meiosis to produce spores and then
undergoes mitosis
...
End division results in a

mature ascus with 8 ascopores
...
Order
of products is preserved
...
Start of as being
haploid- fuse and become diploid

• Can look at any particular breeding structure and know exactly what
happened
