Homework CFU (1 min)

•Question #1 – How many chromosomes

did you receive from each parent?

•Question #2 – Why is it important that

chromosomes undergo replication to form

sister chromatids?

Homework CFU (1 min)

• Question #3 – How many cells result from Meiosis I? Indicate

the number of chromosomes (n or 2n) in each of the cells and

whether or not the chromosomes contain sister chromatids.

• Question #4 - How many cells result from Meiosis II? Indicate

the number of chromosomes (n or 2n) in Meiosis II and

whether or not the chromosomes contain sister chromatids.

Box Today’s Objectives (2 min)

• 2.1.A (Meiosis)

▫ I can describe each phase of

mitosis and how it is an early

step in sexual reproduction

in which pairs of

chromosomes separate and

segregate randomly during

cell division to produce

gametes containing one

chromosome of each type.

• 2.1.B (Fertilization)

▫ I can describe how new

combinations of alleles

may be generated in a

zygote through the fusion

of male and female

gametes.

Hook – Meiosis Matching Competition (5 min)

•Match pictures to labels

•You may use your notes!

•Pairs at tables versus each other.▫(3 people? Pair vs Individual)▫(2 people? Individual vs Individual)

•Winners get the starbursts :D

Investigation Before Explanation (5 min)

• Pairs work together

• Definitions

▫ Sexual Reproduction

Two organisms (male and female), unique offspring

▫ Asexual Reproduction

One organism, identical offspring, quicer

• Who reproduces using sex?

• Put each organism into a pile: sexual or asexual

• How’d you do? Flip over

Teacher Notes – Fertilization (3 min)

• Sex = Variation

• Fertilization:

▫ Sperm + Ovum = Zygote

Sperm = male gamete

Ovum = female gamete

Zygote = first cell of

human Example. Smell = Attraction(Immune System Variation = Stronger Children)

Student Practice – Fertilization (3 min)

Write down in a way that you can remember the question!!

1. Gamete is a __________ cell.2. Haploid human cell = __ chromosomes.

Example is a _________.3. A diploid human cell = __ chromosomes.

Example is a ________.

Teacher Notes – Fertilization (more depth in next homework) (3 min)

n=23egg

sperm n=23

2n=46zygote

Student Practice – Fertilization (3 min)

1. A gamete contains 3 chromosomes:a) The haploid number is ___.b) The diploid number is ___.

2. A zygote contains 8 chromosomes:a) The haploid number is ___.b) The diploid number is ___.

Teacher Notes = Spermatogenesis (4 min)

•Start = primary spermatocyte.•Meiosis I Secondary spermatocytes.•Meiosis II spermatids.•Mature to sperm cells

Student Practice – Spermatogenesis (4 min)1. Spermatogenesis makes __ sperm.2. A sperm has ___ chromosomes so it is a

______ cell.3. After Meiosis I. Each cell has (n / 2n)

chromosomes and they (do / do not) have sister chromatids.

4. After Meiosis II. Each cell has (n / 2n) chromosomes and they (do / do not) have sister chromatids

Teacher Notes – Oogenesis (4 min)

•Start = primary oocyte•Meiosis I 1 secondary oocyte and 1st polar body•Meiosis II 1 ovum and 3 polar bodies

**Note: 1st polar body splits = 2 polar bodies. Secondary oocyte splits = one ovum + one polar body.

Student Practice – Oogenesis (4 min)

1. Oogenesis makes __ ovum.2. Oogenesis makes __ polar bodies.3. An ovum has ___ chromosomes so it is a

______ cell.

Check for Understanding (1 min)

•How are you feeling? (1 through 10)
