Genetics review questions for Phylogeny Lesson

Define microsatellite.

• Short, repetitive sequences of DNA that are used as genetic markers.

• Long, non-repetitive sequences of RNA that code for proteins.

• Single nucleotide polymorphisms that occur in coding regions of genes.

• Large segments of DNA that are involved in chromosomal rearrangements.

Explain genetic diversity.

• The total number of genetic characteristics in the genetic makeup of a species.

• The variety of species within a habitat.

• The process by which organisms adapt to their environment.

• The total number of individuals in a population.

A gene is a _________ of DNA

• segment

• strand

• molecule

• chain

What does it mean if two species share a common ancestor?

• It indicates that they have evolved from a shared lineage.

• They inhabit the same geographical area.

• They have identical DNA sequences.

• They are part of the same ecosystem.

What is a Phylogenetic Tree?

• A diagram that shows the evolutionary relationship of different groups.

• A chart that displays the geographical distribution of species.

• A table that lists the characteristics of various organisms.

• A graph that represents the population growth of a species.

Define phenotype.

• The genetic makeup of an organism.

• The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

• The process by which organisms adapt to their environment.

• The study of heredity and the variation of inherited characteristics.

Which pride is the most genetically diverse based on microsatellite data?

• Sabi Sands

• Kruger National Park

• Masai Mara

• Serengeti

What is the significance of genetic markers in phylogenetic studies?

• They help in identifying genetic relationships and evolutionary history among species.

• They are used to measure the physical traits of organisms.

• They assist in the classification of species based on habitat.

• They provide information about the geographical distribution of species.

Does the genetic data support the geographic data for the lion prides?

• Yes, in general, prides that live closer geographically are more genetically similar.

• No, there is no correlation between genetic and geographic data.

• Yes, but only for prides in Africa.

• No, genetic data is unrelated to geographic distribution.

What is a karyotype?

• A visual representation of an individual's complete set of chromosomes.

• A type of genetic mutation that affects chromosome structure.

• A method for measuring the length of DNA strands.

• A technique used to clone organisms.
