Chapter 12: Q. 6 (page 326)

Which is one of the seven characteristics that Mendel observed in pea plants?

a. flower size

b. seed texture

c. leaf shape

d. stem color

Short Answer

Expert verified

The correct answer is option b

Step by step solution

01

Step 1. Introduction

Hybridisation experiment was conducted on Garden pea plant by Mendel and he selected 7 pairs of contrasting characters.

02

Step 2. Explanation of the correct option

Option b is correct because Mendel selected seven pairs of contrasting characters of pea plants for his experiment which include pea color, pod shape, pod color, flower color, plant height, and position of flowers.

03

Step 3. Explanation of the incorrect options 

Option a is incorrect because flower size was not selected by Mendel for his experiment.

Option c is incorrect because the leaf shape was not selected by Mendel for his experiment.

Option d is incorrect because stem color was not selected by Mendel for his experiment.

Figure 12.5In pea plants, round peas ( R ) are dominant to wrinkled peas ( r ). You do a test cross between a pea plant with wrinkled peas (genotype rr ) and a plant of unknown genotype that has round peas. You end up with three plants, all of which have round peas. From this data, can you tell if the round pea parent plant is homozygous dominant or heterozygous? If the round pea parent plant is heterozygous, what is the probability that a random sample of 3 progeny peas will all be round?

A heterozygous pea plant produces violet flowers and yellow, round seeds. Describe the expected genotypes of the gametes produced by Mendelian inheritance. If all three genes are found on the same arm of one chromosome should a scientist predict that inheritance patterns will follow Mendelian genetics?

The gene for flower position in pea plants exists as axial or terminal alleles. Given that axial is dominant to terminal, list all of the possible F1 and F2 genotypes and phenotypes from a cross involving parents that are homozygous for each trait. Express genotypes with conventional genetic abbreviations.

Can a human male be a carrier of red-green color blindness?

A scientist pollinates a true-breeding pea plant with violet, terminal flowers with pollen from a true-breeding pea plant with white, axial flowers. Which of the following observations would most accurately describe the F2 generation?

a. 75% violet flowers; 75% terminal flowers

b. 75% white flowers in terminal position

c. 75% violet flowers; 75% axial flowers

d. 75% violet flowers in an axial position
