Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line

Probability of Inheritance

front 1

Which describes the notation Tt for the trait of plant height?

back 1

heterozygous genotype

front 2

Which term describes an organism that has identical alleles for a trait?

back 2

Homozygous

front 3

The offspring of a particular cross are 100 percent heterozygous for the trait of plant height. What were the most likely genotypes of the parents?

back 3

TT x tt

front 4

Mendel crossed two plants that were heterozygous for the trait of flower color. Which genotypes could he have used to represent the cross?

back 4

Pp x Pp

front 5

In pea plants, tallness (T) is dominant to shortness (t). What are the predicted percentages of the genotypes of the offspring if a homozygous short plant is crossed with a heterozygous tall plant?

back 5

50 percent Tt, 50 percent tt

front 6

Which describes the mating of organisms that have different homozygous alleles for a single trait?

back 6

monohybrid cross

front 7

A dihybrid cross is created from plants that are heterozygous for both round seeds and yellow seed color. What is the ratio of offspring that have round seeds and yellow seed color?

back 7

9:16

front 8

Which includes the physical characteristics of an organism?

back 8

phenotype

front 9

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. In this cross, tallness (H) is dominant to shortness (h).

Based on the Punnett square, what is the phenotype of the offspring?

back 9

Tall

front 10

A plant can produce either purple flowers or white flowers. The purple flower color is dominant over the white flower color. What is the ratio of the offspring with purple flowers to the total number of offspring if two plants that are heterozygous for purple flowers are crossed?

back 10

3:4

front 11

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait.

Based on the Punnett square, what is the probability that the offspring will have freckles?

back 11

75 percent

front 12

There are two different alleles for flower color, P and p. The image shows a white sweet pea with a genotype of pp.

back 12

White petal color is a recessive trait.

front 13

There are two different alleles for flower color, P and p. The image shows a purple sweet pea that is labeled with its two alleles for petal color.

Which is the genotype of the sweet pea?

back 13

homozygous dominant

front 14

Why did Gregory Mendel choose to use purebred plants in his experiments?

back 14

They exhibit only one form of a trait.

front 15

What is one of the reasons why Gregory Mendel chose to study pea plants?

back 15

They reproduce sexually.

front 16

Gregory Mendel crossed homozygous tall plants (TT) with homozygous short plants (tt). All the resulting offspring were tall. From these results, what conclusion did Mendel draw?

back 16

Tallness is a dominant trait.

front 17

Purple flowers are dominant over white flowers. A heterozygous purple flower is crossed with another heterozygous purple flower. What will the ratio of purple to white be?

back 17
