One character in peas that Mendel studied was yellow versus green seeds.
A cross between a homozygous yellow line (YY) and a homozygous green line (yy) will result in F1 plants that are heterozygous (Yy) for this trait and produce yellow seeds.
When an F1 plant undergoes meiosis, what gamete types will it produce, and in what proportions?
Use your understanding of Mendel's law (or principle) of segregation to label each gamete possibility as "correct" or "incorrect. a. incorrect
b. correct
c. incorrect
d. incorrect
e. incorrect
f. incorrect

1/2 will be Y

1/2 will be y

Explanation:

In the process of meiosis haploid gametes are formed which means one gamete contains half the information from the parent cell (one set of 23 chromosomes). Because of Mendel's law (or principle) of segregation, if the parent has genotype heterozygous (Yy), it will be divided in two gametes in the following way:

Yy will be broken in to Y + y.

One gamete will be Y the other gamete will be y  

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
