Insect Reproduction
Cards in this deck (22)
- 1What is the definition of Reproduction?the act or process of reproducing; specifically the process by which plants and animals give rise to offspring
- 2Why are Insects so effective in their ability to survive?High Reproductive Potential
- 3What are the 2 major cell types in AnimalsSomatic Cells, Germ Cells
- 4What are somatic cells in insects?Cells that make up all the cells that are not reproductive
- 5What are Germ cells in insects?Reproductive Cells gametes, zygote (etc)
- 6What is the genetic material in Somatic Cells?Have a full complement of chromosome pairs:
- 7What are chromosomes?thread like structures of DNA and protein in cell nucleus that contain genes (usually paired)
- 8How many Chromosomes do Homosapiens have?23 pairs
- 9How many chromosomes do Drosophita (fruit flies) have?4 pairs
- 10What happens when germ cells divide through Meisosis and Mitosis?They form gametes, and each receives only one set of chromosome
*Haploid Condition* - 11What are the types of Reproduction in Insects?Typical (hetero), Asexual, and Haplo-diploidy
- 12Describe Typical Reproduction amongst insectsMales and females mate,
Male passes haploid sperm to female, fertilization of the Haploid egg results in Diploid Embryo - 13Describe Asexual Reproduction amongst insectsFemales produce diploid eggs
the eggs develop into diploid females =
genetic clones of the mother
(issue): Genetic InDiversity can be lethal to species - 14Describe the Haplo-diploidy Reproduction strategyMale somatic sperms and cells are haploid
Female somatic cells are diploid & eggs are haploid
Females choose to fertilize the egg or not
unfertilized eggs ->male
Fertilized egg -> female - 15What insects have Haplo-diploidy Reproduction?Honeybees
- 16List the many Birthing Strategies of InsectsMating Behavior
Avoid mating error
Territorialilty
Female Choice
Paternity Assurance - 17Describe the Birthing Strategy Mating Locationinvolves appearance, courtship displays, light signals, sounds, and a female required resource
- 18How do Insects Avoid Mating Mistakes?Behavioral Strategies, Courtship rituals, "Lock and Key" genitalia
- 19What are some examples of Insect Genetic Errors?Non Viable fertilization, Death of the embryo, Infertile offspring
- 20What is Territoriality Mating comprised of?defending the territory and killing other suitors to "keep females to themselves"
- 21What is the Female Choice Theory?that females of all species are the main proponents in choosing who gets to mate with them
- 22What is Paternity Assurance?Insect Males ensure that offspring is theres and will go through far lengths to do so
