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