What is the most diverse fungal phylum?
Phylum Ascomycota
What is the ascus?
The defining feature in a microscopic sexually structure
Where is the ascospores formed?
In the ascus
What way do they reproduce?
Both sexually and asexually
What is Plasmogamy?
The fusion of two hyphae together
What is Dikaryotic stage?
Cells have two haploid nuclei
What is Karyogamy?
Nuclei fuse together and create one diploid nucleus
What is meiosis in ascomycetes?
Results in four cells haploid ascospores
What is mitosis in ascomycetes?
Cells divide to form eight ascospores in an ascus
What is dispersal?
Mature ascus release the ascospores to start a new mycelium
What is sodaria fimicola?
Microscopic ascomycete that has a life cycle of 1-2 weeks. Spends most of its life in a haploid vegetative state.
What is tetrad analysis?
Tetrad refers to the four spores created after meiosis in the Ascomycota life cycle
What is gene linkage?
The tendency of genes that are located close to each other on the same chromosome to be inherited together during meiosis
When traits are frequently seen inherited together we can create a what?
genetic map
What is genetic mapping?
When 2 traits are regularly inherited together, therefore we can determine that the genes are close together on a chromosome.
What are the ways to make a linkage map?
crossbreeding, tracking traits, or recombination frequency
What is the recombination frequency?
recombinants/total offsprings x 100%
Sordaria is good to use in labs for what experiments?
For conducting tetrad analysis for the segregation for score colored mutants.
How is ascopore color determined?
By the genotype of the spore. (It can be observed in the ascus)
What is sickle cell?
It is an inherited blood disorder that affects around 5 million people worldwide. The body is not able to create hemoglobin– a protein that transports oxygen.
Is sickle cell recessive or dominant?
recessive
What does a sickle cell look like?
c-shaped, stiff, prone to clotting, and a life span of 15 days
