Which of the following is an example of a biological trait?

eye color
regional accent
Mendel began his experiments with purebred pea plants. This approach enabled him to determine that variations among offspring were a result of
random mutations
self-pollination
genetic uniformity
his crossings
Mendel was able to identify predictable patterns of heredity. He succeed mainly because he chose to study traits that
were always dominant
tended to be recessive
could be diluted
only had two forms
Which of the following conclusions was a result of Mendel's observations?
Organisms that give rise to purebreds are genetically superior
Organisms that have intermediate features are self-pollinating
Organisms inherit two copies of each gene, one from each parent
Organisms that self-pollinate do not have "either-or" features

Homozygous dominant is a completely filled-in entry, homozygous recessive is blank. That means heterozygous is only partially filled in. If we are using W for our alleles what is the genotype of box 12?
WW
