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 |
