(100% Correct Answers) Already Graded A+
Character [ Ans: ] an observable heritable feature.
Trait [ Ans: ] any detectable variation in a genetic
character.
True-breeding [ Ans: ] Referring to plants that produce
offspring of the same variety when they self-pollinate.
Hybridization [ Ans: ] carries two different alleles of the
same gene
P generation [ Ans: ] parental generation
F1 generation [ Ans: ] first filial generation (the word filial
from the Latin word for "son"), the hybrid offspring of the
P generation.
F2 generation [ Ans: ] (second filial generation), offspring
of the F1 hybrids' self-pollination.
Alleles [ Ans: ] Alternate versions of a gene.
Punnett Square [ Ans: ] a diagram that helps you predict
the allele composition of offspring from a cross between
individuals of known genetic makeup.
, Homozygous [ Ans: ] an organism having a pair of
identical alleles for a character is said to be ___________ for
the gene controlling that character.
Heterozygous [ Ans: ] an organism that has two different
alleles for a gene is said to be ____________ for that gene.
Phenotype [ Ans: ] an organism's traits.
Genotype [ Ans: ] an organism's genetic makeup.
Law of Independent Assortment [ Ans: ] Each pair of
alleles segregates independently of other pairs of alleles
during gamete formation and combines independently of
each other.
Rules of Multiplication [ Ans: ] To determine the
probability of two or more independent events, you
multiply the probability of one event by the probabilities
of the other events.
Rules of Addition [ Ans: ] If you add up the individual
probabilities of two or more mutually exclusive events,
you can predict the probability for any one of them to
occur.
Incomplete dominance [ Ans: ] is the blending of traits.
ex: red snapdragon plant and white snapdragon plant
produce pink snapdragon plant.
