Individuals with the AS genotype for sickle cell disease and individuals with the AA genotype differ in terms of their susceptibility to which disease?


Which of the following is not one of the assumptions a population must meet to be in Hardy-Weinberg equilibrium?

Random selection

What is the significance of heterozygote advantage in the context of genetic diseases like sickle cell disease?

It confers an advantage in certain environments, promoting the persistence of genetic diseases

In what type of environment are individuals with the AS genotype for sickle cell disease less susceptible to malaria?

A tropical environment

Which characteristic distinguishes prokaryotic cells from eukaryotic cells in terms of genetic material?

Location of genetic material in a nucleoid

What is the primary role of the cell wall in most prokaryotic cells?

Maintaining cell shape and preventing bursting in hypotonic environments

Why does natural selection act on phenotypes and not genotypes?

Phenotypes determine an organism's survival and reproduction

Which process can introduce new genetic variation into a population?

Gene flow

In Hardy-Weinberg equilibrium, what does the equation p^2 + 2pq + q^2 = 1 represent?

Genotypic frequencies in a population

What is an assumption of a population in Hardy-Weinberg equilibrium?

No mutation

Why is sickle cell disease considered an example of heterozygote advantage in some environments?

Heterozygous individuals are resistant to malaria

How does genetic drift impact small populations?

Leads to significant evolutionary changes

What is the main mode of reproduction for Phylum Chytridiomycota?

Mainly asexually through zoospores

Which fungal phylum is noted for being aquatic and having motile spores?


What is the main reproduction method for Phylum Zygomycota?

Asexually by sporangiospores

Which fungal phylum includes yeasts, molds, and morels, and is responsible for fermentations and antibiotic production?


Which fungal phylum is mostly found on decaying plant and animal matter and is important in soil fertility?


Which fungal phylum has asci (sacs) as structures where spores are formed?


Explore the concepts of natural selection, gene flow, and genetic drift in the context of evolution. Understand how these mechanisms affect allele frequencies and shape populations over time. Learn about the impact of differential survival, reproduction, and genetic variation on evolutionary processes.
