Q

VARIATION TYPES - Reproduction

SEXUAL

  • how many parents?
  • 2 key processes
  • ____ or ___ are produced
  • offspring are ____ of the parents
A
  • biparental
  1. meiosis
  2. fertilization
  • sex cells or gametes
  • variants
17
Q

VARIATION TYPES - Reproduction

SEXUAL - MEIOSIS

may produce:
- _____ reproductive units called _____ if they _____ directly into ____, or;
- _____ if they ____ together to produce the ____

  • 3 types + definition
A
  • haploid
  • spores
  • develop into adults
  • gametes
  • fuse
  • adults
  1. Gametic Meiosis — the direct products of meiosis are gametes
  2. Sporic Meiosis — the direct products of meiosis are spores
  3. Zygotic Meiosis — the zygote does not develop into an adult but directly undergoes meiosis to produce haploid cells that develop into haploid adults
18
Q

VARIATION TYPES - Reproduction

SEXUAL - FERTILIZATION

  • refers to the ____ of ____ ____ resulting into a ____ ____ product called a ____
  • 2 types
A
  • union of 2 gametes
  • unicellular diploid
  • zygote
  1. Syngamy — both gametes physically fuse to produce the zygote.
  2. Conjugation — protoplasts or genetic material from one of the gametes is transferred to the other gamete where the fusion event takes place.
19
Q

3 forms of SYNGAMY

A

a. Isogamy — both gametes are alike in size and appearance
b. Anisogamy — one of the gametes is larger than the other
c. Oogamy — gametes differ in appearance, the male is smaller and motile while the female is large and non-motile.
