300
The physical expression of an organism's genes is known as

In garden peas, tall vine (T) is dominant and short vine (t) is recessive. A homozygous tall pea plant is crossed with a homozygous short pea plant.
Give the genotype of the homozygous tall pea plant: _______
TT

c. mutated.
d. recessive.
b. dominant

Which statement below is the best comparison of mitosis and meiosis?
a. Meiosis is two division cycles with a result of haploid cells. Mitosis is one division cycle and results in diploid daughter cells.
b. Meiosis is two divisions cycles and results in diploid cells, while mitosis is one division and results in haploid cells.
c. Mitosis is two division cycles and results in diploid daughter cells, while meiosis is one division cycle and results in haploid gametes.
d. Mitosis is two division cycles and results in haploid gametes, while meiosis is one division cycle and results in diploid daughter cells.
