2 Homework Due Today (0 min) - Stamp Human Development YouTube Video Notes & Problems (Page 37.F)Egg
3 Daily QuestionPage 37.AIf you were to die today, what would be your epitaph? (the phrase on your tombstone) Why would you want that to be your epitaph?
4 Homework CFUPage 37.FStages for pregnancy? Dilation, Expulsion, Placental Stage?Ages for each stage of life?Puberty symptoms for boys and girls? Ages?
5 Essential Skills and Knowledge Page 37.A2.2.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.
6 Transition and Warning Genetic disorders resulting from mistakes in meiosis
7 HookAn employee with down syndrome insulted by customers. What Would You Do?
8 Investigation Before Explanation # 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?
9 Teacher Notes (Page 37.C)Nondisjunction: Failure of chromosomes to separate normally during meiosisIn general, risks increase with mom’s age
10 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?
11 Teacher Notes (Page 37.C) Monosomy: Loss of a chromosome (2n-1) Only survivable monosomy: Turner SyndromeOnly one X chrom. (girls)Short, swelling, broad chest, low-set ears, webbed necksNon-working ovariesDifficulties in mathematics and memory
12 Student Practice (Page 37.C) A human being with monosomy has __ chromosomes.
13 Teacher Notes (Page 37.C)Trisomy: Addition of a chromosome (2n+1)
14 Trisomy 21 – Down Syndrome Teacher Notes (Page 37.C)Trisomy 21 – Down SyndromeMost common trisomyDelay in learningSmall chin, face is flat & broad, short neck
15 Trisomy 18 – Edwards Syndrome Teacher Notes (Page 37.C)Trisomy 18 – Edwards Syndrome2nd most common trisomy80% femaleMajority die before birthLow survival rateheart abnormalities, kidney malformations, etc.Symptoms: small head , malformed ears, widely spaced eyes, clenched hands
16 Trisomy 13 – Patau Syndrome Teacher Notes (Page 37.C)Trisomy 13 – Patau Syndrome>80% die in 1st yearSevere heart and kidney defectsMental retardation, eye defects, extra fingers, low-set ears, deformed feed
17 Student Practice (Page 37.C) A human being with trisomy has __ chromosomes.
18 CFU Rate 1-10 Human Development Genetic Disorders Resulting from Mistakes in Meiosis
19 Lecture ActivityPartner 1 draw nondisjunction if it occurs to the homologous pairsPartner 2 draw nondisjunction if it occurs to the sister chromatidsProphase I Metaphase I Anaphase I Telophase I Prophase II Metaphase II Anaphase II Telophase II
