In which phase of meiosis do Tetrads align along cell equator? -
ANSWERS-metaphase I
Three origins of genetic variation - ANSWERS-independent assortment
of chromosomes, crossing over, random fertilization
Independent assortment of chromosomes - ANSWERS-The random
distribution of maternal and paternal chromosomes into gametes during
meiosis
Random fertilization - ANSWERS-the combination of each unique
sperm with each unique egg increases genetic variability
What is an advantage of sexual reproduction? - ANSWERS-genetic
variation

trait - ANSWERS-A characteristic that an organism can pass on to its
offspring through its genes
true-breeding - ANSWERS-term used to describe organisms that
produce offspring identical to themselves if allowed to self-pollinate
Hybridization - ANSWERS-Breeding technique that involves crossing
dissimilar individuals to bring together the best traits of both organisms
Alleles - ANSWERS-alternative versions of a gene
dominant - ANSWERS-Describes a trait that covers over, or dominates,
another form of that trait.
recessive - ANSWERS-An allele that is masked when a dominant allele
is present

How did Mendel cross-pollinate pea plants? - ANSWERS-he removed
the male parts from one plant and dusted their pollen onto the female
parts of another plant
Function of a test cross - ANSWERS-to determine if this individual is
homozygous dominant or heterozygous - a way to explore the genotype
of an organism
What does a test cross involve? - ANSWERS-breeding the individual in
question with another individual that expresses a recessive version of the
same trait
The three generations that Mendel studied - ANSWERS-P generation,
F1 generation, and the F2 generation
P generation - ANSWERS-Parental generation, the first two individuals
that mate in a genetic cross
