Chapter 11 Intro to Genetics Flashcards
first group of plants produced by cross-pollination
F1 Generation
the organism has two identical alleles for a particular trait. TT or tt. PUREBRED
Homozygous
Factors that control traits
genes
passing of traits from parents to their offspring
heredity
parental purebred plants. each plant has the same type of alleles
P generation
the organism has two different alleles for the same trait
heterozygous
self-pollinated plants that produce offspring that are identical to the parent
purebred
genetic makeup of alleles
genotype
plants produced by crossing parents with different characteristics
hybrids
physical characteristics of the offspring
phenotype
transfer of pollen from the flower of one plant onto a flower of another plant
cross pollination
some alleles are more noticeable or occur more often (dominant) and some are less noticeable or occur less often (recessive).
dominance
different forms of genes
alleles
transfer of pollen from male to female flower part to produce seeds
pollination
process in which pollen from one flower falls onto a flower of the very same plant
self-pollination
characteristics that parents pass to offspring
traits
only seen when it is not with a dominant, lower case letter
recessive
TT or tt
homozygous
Tt
heterozygous
What is the difference between hybrid and purebred?
Hybrid is heterozygous, the alleles are different, and purebred is homozygous, the alleles are exactly the same or similar
tt, short plant
recessive
TT, Tt, tall plant
dominant
What are four things you can know about a plant based on its gentype?
The height, color, shape, position
Examples of plant height
short, tall
examples of plant color
yellow, green
examples of plant shape
constricted, smooth
examples of plant position
terminal, axial
GREAT JOB!!!
YOU ARE DOING AMAZING!!!!!!!!!!!
