Today’s 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- IDENTIFY the possible gametes from a given parent cell

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

(monohybrid / dihybrid)

Vocabulary

These should be done by test day!

-genetics -allele -dominant / recessive -homozygous / heterozygous -genotype / phenotype -law of segregation / law of independent assortment -hybrid

10.2 MENDELIAN GENETICS

WHAT YOU WILL LEARN -Law of Segregation

-Law of Independent Assortment

-How to use a Punnett square

10.2 MENDELIAN GENETICS

MAIN IDEA

Mendel explained how a dominant allele can mask the presence of a recessive gene.

READING Q’s DEFINE

-What is a true breeding plant?

-same form of trait from generation to generation

READING Q’s LABEL

-Fill in the boxes with the name of each generation of offspring. Draw the peas you would expect to see in the empty pods. Use shading to indicate a green pea.

F-1

F-2

READING Q’s APPLY

-In Mendel’s experiment with green and yellow seeds, what was the dominant trait?

-yellow seeds

READING Q’s PREDICT

-What would be the phenotype of a homozygous, recessive (yy) pea plant?

-green seeds

READING Q’s APPLY

-True-breeding yellow-seeded and green-seeded plants are crossed and produce yellow-seeded offspring. Which of these plants is a hybrid?

-yellow-seeded offspring

READING Q’s IDENTIFY

-What is one purpose of a Punnett square?

-tracking genotypes/phenotypes

-predicting ratios of cross outcomes

READING Q’s DEFINE

-Circle the genotypes in the small squares that will give a yellow-seed phenotypic ratio in the offspring? What will be the phenotypic ratio in the offspring?
