Essential Skills and Knowledge• Page 37.A

• 2.2.D (Juvenile Stages): I can describe the different developmental characteristics of a human being throughout various stages of their growth including the human neonate, infant, toddler, preschooler, elementary, junior high, and high school.

• 2.2.E (Adulthood): I can describe the different developmental characteristics of a human being throughout various stages of adulthood.

Investigation Before Explanation• http://www.youtube.com/watch?v=EA0qxhR2oOk

• # chromosomes in a gamete with zero copies of a chromosome?▫ If fertilized with a normal gamete, how many total

chromosomes would the zygote have?

• # chromosomes in a gamete with two copies of a chromosome?▫ If fertilized with a normal gamete, how many total

chromosomes would the zygote have?

Teacher Notes (Page 37.C)•Nondisjunction: Failure of chromosomes

to separate normally during meiosis•In general, risks increase with mom’s age

Page 10: Unit 4, Day 4 Genetics & Human Development Thu, Jan 24 th (Block, 115 min) Fri, Jan 25 th (Block, 85 min)

Student Practice (Page 37.C)

•If nondisjunction occurs to the homologous pairs, how many total chromosomes end up in each of the four gametes?

•If nondisjunction occurs to the sister chromatids, how many total chromosomes end up in each of the four gametes?

Page 11: Unit 4, Day 4 Genetics & Human Development Thu, Jan 24 th (Block, 115 min) Fri, Jan 25 th (Block, 85 min)

Teacher Notes (Page 37.C)• Monosomy: Loss of a

chromosome (2n-1)

• Only survivable monosomy: Turner Syndrome

▫ Only one X chrom. (girls)

▫ Short, swelling, broad chest, low-set ears, webbed necks

▫ Non-working ovaries

▫ Difficulties in mathematics and memory

Page 12: Unit 4, Day 4 Genetics & Human Development Thu, Jan 24 th (Block, 115 min) Fri, Jan 25 th (Block, 85 min)

Student Practice (Page 37.C)

•A human being with monosomy has __ chromosomes.

Teacher Notes (Page 37.C)

•Trisomy: Addition of a chromosome (2n+1)

Page 14: Unit 4, Day 4 Genetics & Human Development Thu, Jan 24 th (Block, 115 min) Fri, Jan 25 th (Block, 85 min)

Trisomy 21 – Down Syndrome

• Most common trisomy

• Delay in learning

• Small chin, face is flat &

broad, short neck

Teacher Notes (Page 37.C)

Page 15: Unit 4, Day 4 Genetics & Human Development Thu, Jan 24 th (Block, 115 min) Fri, Jan 25 th (Block, 85 min)

Trisomy 18 – Edwards Syndrome• 2nd most common trisomy

• 80% female

• Majority die before birth

• Low survival rate

▫ heart abnormalities,

kidney malformations, etc.

• Symptoms: small head ,

malformed ears, widely

spaced eyes, clenched

hands

Teacher Notes (Page 37.C)

Page 16: Unit 4, Day 4 Genetics & Human Development Thu, Jan 24 th (Block, 115 min) Fri, Jan 25 th (Block, 85 min)

Trisomy 13 – Patau Syndrome

• >80% die in 1st year

• Severe heart and kidney

defects

• Mental retardation, eye

defects, extra fingers, low-

set ears, deformed feed

Teacher Notes (Page 37.C)
