INHERITANCE Flashcards
_______ are very good example of nonflowering plant.
FERNS
_______ are special structures that carry reproductive
cells.
SPORANGIA
These reproductive cells will produce _____________
SPORES/ HAPLOID
WHAT OTHER TERM FOR HAPLOID
SPORES
These spores develop through repetitive ______ cell
divisions into a _______ multicellular haploid
organism, gametophyte.
MITOTIC CELLS/ HEART SHAPED
Gametophyte produces_______ (in alternating
manner to avoid self-fertilization)
BOTH GAMETES
During fertilization, the ______of a fern gametophyte
and the _______of another fern gametophyte fuse to form
_______
SPERM/ EGG/ ZYGOTE
Flowering plants reproduce through their
_______
FLOWERS
unisexual (_______) : either____
or ______
DIOECIOUS/ STAMEN/ PISTIL
bisexual (________) : have ______of
them
MONOECIOUS / BOTH
In ______ generation, flowering plants
produce ___types of spores:
SPOROPHYTE/ TWO
located at stamen
MICROSPORES
undergoes meiosis to produce
haploid microspores that develops
into a male gametophyte (pollen
grain)
MICROSPORES
located at ovule
MEGASPORES
undergoes meiosis to produce
haploid megaspores that develop
into a female gametophyte (embryo
sac)
MEGASPORE
Different types of pollinating agents will
lead the ______ to a viable flower’s
__________.
POLLEN GRAIN/ POLLEN TUBE
This allows the pollen grain to penetrate
the _____ gametophyte to produce a
________.
ZYGOTE
The _______is enclosed in a drought-
resistant seed that contains _________
that is protected by a _________.
ZYGOTE/FOOD SUPPLY/ HARD COATING
Then the seed may lie in a ______state for
______or _____, waiting for conditions
favorable to the development of a new flower-
bearing plant.
RESTING/ MONTH/ YEAR
revolutionized the study of heredity
he did this through observation traits in
thousands of garden peas
GREGOR MENDEL
the passing on of characteristics
contained in the chromosomes of sex
cells from parents to offspring
HEREDITY
the F1 or the_______________________ was
first generation of offspring from those
peas, and Mendel used mathematical
probabilities to explain his experimental
results and published in his ____________________ 1865
FIRST FILIAL GENERATION
EXPIREMENTS IN PLANT HYBRIDIZATION
what theory di gregor mendel make
PATRICULATE THEORY OF INHERITANCE
Law of dominance and uniformity
MENDELIAN POSTULATE
Law of segregation
MENDELIAN POSTULATE
Law of independent assortment
MENDELIAN POSTULATE
it pertains to inheritance involving one pair of contrasting
traits (alleles)
