Question

1. when does the parent cell copy its dna? check all that apply (3) *

before cell division begins

prophase 1

interphase

metaphase 1

prophase 2

s phase

1. what is meant by homologous chromosomes? *

all the chromosomes you get from one parent

chromosomes that are identical copies

chromosomes that code for the same traits, but come from different parents

all the chromosomes at the start of cell division

Explanation:

• Question 3: DNA replication occurs in the S phase of interphase, which is before cell division begins. Prophase 1, metaphase 1, and prophase 2 are stages of meiosis where DNA replication has already occurred.
• Question 4: Homologous chromosomes are pairs of chromosomes that code for the same traits (e.g., eye color gene location), but one comes from the mother and one from the father. They are not identical copies (those are sister chromatids after S - phase) and not all chromosomes from one parent or all at the start of cell division.

Answer:

• Question 3: before cell division begins, interphase, S phase
• Question 4: Chromosomes that code for the same traits, but come from different parents
