UNIT OBJECTIVES

10.2 MENDELIAN GENETICS

1-EXPLAIN the significance of Mendel’s experiments to the study of genetics

2-SUMMARIZE the “law of independent assortment” & the “law of segregation”

3-DISTINGUISH the difference between dominant/recessive traits

4--- PREDICT the outcome of a genetic cross using the laws of probability

5--- PREDICT the possible offspring (genotypes / phenotypes) from a cross

using a Punnett square (monohybrid / dihybrid)

Add on to each QUESTION every night as REVIEW!

FOR REVIEW

INTRODUCTION- [0:00-2:04]

1-IDENTIFY: What did Mendel work with?

-pea plants

2-EXPLAIN why pea plants are good organisms for studying

genetics.

-# characteristics

-many offspring from 1 pod

PUNNETT SQUARES- [2:04-5:21]

3-IDENTIFY: What is the P cross?

-parents [1st cross in genetics]

4-IDENTIFY: What is the F1 cross?

-filial [offspring]

5-DESCRIBE the incorrect idea of ‘blending”.

-traits blend @ all times / NOT true

6-DEFINE hybrid-

-Tt [carried dominant & recessive allele]

PUNNETT SQUARES- [2:04-5:21]

7- EXPLAIN the purpose of Punnett Squares [2]

-% offspring for the trait [predict outcomes]

-track genotypes / phenotypes

8-DRAW the set-up for a Punnett Square.

[where does the male / female info go?]

MENDEL’s LAWS- [5:21- 7:38]

9-DEFINE: Law of SEGREGATION

-alleles separate

10-PROVIDE an example

11-DEFINE: Law of INDEPENDENT ASSORTMENT

-alleles sort independently [most]

12-PROVIDE an example

PROBABILITY

Method developed by Dr. Reginald Punnett in the early 1900s

-used to predict possible genetic combination of alleles.

-allele combinations inherited are like the probability of

flipping coins- it is an estimated outcome

DEFINE probability:

-likleyhood of event occurring

-chance of something happening

PUNNET SQUARES / PROBABILITY

DEMONSTRATE the probability of inheritance of genes by

flipping coins.

-probability of a coin landing on heads when flipped once is

½ = 50%

-probability of 2 coins landing on heads when flipped once is\

½ x ½ = ¼ 25%

PREDICT the probability of tossing 2 coins at the same time

_____ -having them both land on heads (HH)

_____ -having then both land on tails (TT)

_____ -have 1 land on heads and 1 land on tails (HT)

PUNNETT SQUARES: COIN TOSS

Take 2 pennies and toss them at the same time for 50 trials.

BOTH heads (HH) 1HEAD/1TAIL (HT) BOTH tails (TT)

TOTAL __________ __________ __________

IDENTIFY the RATIO of your results for 50 tosses-

_____:_____:_____

HH HT TT

EXPLAIN how is probability used in the study of genetics?

-used to determine the possibilities of offspring having a certain trait.
