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?
