Sexual reproduction and development practice questions

Mitosis is _____ reproduction because all offspring (known as daughter cells) have the DNA from only one parent and are clones of that parent

• sexual
• asexual
• fertilization
• haploid

the single cell that is made when sperm and egg combine their genetic material (DNA)

• zygote
• gamete
• somatic
• haploid

This type of cellular reproduction is important because it allows organisms to grow and also repairs damaged tissue by replacing dead or injured cells

• mitosis
• meiosis
• fertilization

What occurs in meiosis but NOT mitosis

• crossovers between homologous chromosomes

• crossovers between sister chromatids

• spindle formation

• chromosome number is conserved

Differences in DNA between individuals or populations

• Environmental Variation

• Genetic Variation

• Adaptive Feature

• Genetic Engineering

Which of the following is the best definition for MEIOSIS?

• the process of two haploid cells uniting

• the counting of chromosomes within a diploid cell

• a two-step process that reduces the number of chromosomes in half such that there is only one copy of all the chromosomes

• the equational division of a cell into two identical copies

Which of the following are CORRECT observations about the differences between MITOSIS and MEIOSIS? (Check all that apply.)

• Mitosis produces cells that identical to the parent cell.

• Meiosis produces cells that have half the number of chromosomes as the parent cell.

• All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.

• In both types of cell division, the chromosomes are only duplicated once.

• Only in Mitosis, do you see chromosomes pair up to form a tetrad.

The products of MEIOSIS have _______ number of chromosomes.

• haploid

• diploid

What is the function of the human male reproductive system?

• grow and develop baby

• produce egg and deliver egg to female

• internal fertilization

• produce sperm and deliver sperm to female

Which part of the female reproductive system is the site of fertilization?

• Uterus

• Fallopian tube

• Ovary

• Cervix
