Genes are found on
chromosomes
proteins
alleles
gametes
Gregor Mendel discovered that recessive traits
will be hidden by dominant traits
will be mixed with dominant traits
will cover up and hide dominant traits
When discovering dominant traits of a plant, like purple flowers, you are describing its
genotype
phenotype
The genotype symbol (Aa) stands for
homozygous dominant
heterozygous dominant
heterozygous recessive
homozygous recessive
If you cross a white (recessive) flower with genotype (aa) with a purple (dominant) flower with genotype (AA) the possible phenotypes in the offspring will be
100% white
75% purple, 25% white
100% purple
50% purple, 50% white
For the Punnett square shown, the missing genotype symbol of the missing parent is
AA
Aa
aa
In pea plants, yellow peas are dominant over green peas. The correct phenotype order for genotypes AA, Aa, and aa would be
yellow, yellow, yellow
yellow, yellow, green
yellow, green, green
green, green, green
An organism that has inherited two of the same alleles, like aa, would be described as
homogenous
homozygous
heterogenous
heterozygous
An organism that has 12 chromosomes in each body cell would have how many chromosomes in each of its sex cells (gametes)?

Using the Punnett square shown, the genotype of the space represented by "2" is
RRYY

Using the Punnett square shown, a heterozygous round seeded homozygous green seeded plant would be found in square

A flower that pollinates itself is an example of
asexual reproduction
sexual reproduction
When an organism goes through asexual reproduction, like a bacterium that divides into two, the resulting organisms are
genetically different to one another
genetically identical to one another
