Reproduction Bio
Definitions (Lab)
HOMOZYGOUS
condition
individual
inherited gene
same/identical alleles
Black hair genotype (B) & Blonde (b)
BB or bb alleles
HETEROZYGOUS
condition
individual
inherited genes
different alleles
Black hair genotype (B) & Blonde (b)
Bb or bB alleles
SELFING
also called
Self-fertilization
self-pollination
hermaphroditic dioecious plants
flower has both male & female reproductive organ
tomato & gumamela
monoecious plants
male & female flower on same plant
corn
union/fusion
male & female gamete (sex cell)
from the same individual
type of inbreeding
IN-BREEDING
mating of closely related individual
small plant population
high chance of inbreeding
type of inbreeding
self-fertilization
BACK CROSS
transfer of desired genes of a donor parent
into elite plant (recurrent parent)
progeny
crossed-back into elite plant
repreated again & again until a progeny is identical to the recurrent parent + desirable trait
ADVANTAGES
keep desirable traits
or remove undesirable traits
DISADVANTAGES
INBREEDING OF DIOECIOIUS PLANT
impairment of floral scent & spatial floral traits
essential in attracting pollinators
Inbreeding in Dioecious Plant Article
reduced viability
retention of bad genes
offspring weaker than parents
CROSS BREEDING
combine compatible species or variety
w/ desirable traits
create a plant variety or a hybrid
Fuji apple
Virginia Ralls Janet apple
Red Delicious apple
ADVANTAGES
disease resistance
high yield
high survival rate
tolerate extreme weather conditions
adapt to stress
DISADVANTAGES
passing of undesirable traits
many trial & error
not always successful
not always desired traits are passed
takes long to develop
loss of species variety
parent plants are left
hybrid/variations are self pollinated
negatively affect other plant spp
hybrid/variation require more water
surrounding plants will dry up
SYNSEED
synthetic seed
artificial seed
seed or any plant propagation material
artificially enclosed
shoots
buds
embryos
meristematic tissue
used in seedless plants
grapes
watermelon
papaya
tropical countries
philippines
TYPES
DESSICATED SEEDS
HYDRATED SYNTHETIC SEEDS
PURE LINE
offspring
single
homozygous
ex tall (T) & short (t)
parent plant
TT
tt
self-pollinated plant
offspring bear a resemblance to parent
similar genotype & phenotype as the parent plant
genetically identical to the parent
certain characteristics of a parent
appear from gen to gen
