Chapter 24, Problem 1SQ
Summary Introduction

Introduction:

Embryo development is a crucial step for ensuring the survival of any species. Initial development is similar for both vertebrates and invertebrates. As the embryo continues to develop, the specific characteristics of the species emerge at different stages.

Answer to Problem 1SQ

Correct answer:

All chordates have notochord as embryos. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Option c. is given as “notochord.”

As the embryo continues to develop, the ancestral characteristics are seen in the embryo and later specific characteristics of the species emerge at different stages. The nerve cord, notochord, postnatal tail, and pharyngeal slits are the four characteristics that are present in the chordates.

Reason for incorrect answer:

Option a. is given as, “backbone.”

Backbone is the property of vertebrates and all chordates are not vertebrates. So, the embryo of all chordates does not have a backbone. Hence, option a. is incorrect.

Option b. is given as, “jaws.”

Jaws are the characteristic feature of vertebrates and all chordates are not vertebrates. Hence, option b. is incorrect.

Option d. is given as, “both b and c.”

All chordates have notochord. However, all chordates do not possess jaws. Hence, option d. is incorrect.

Hence, the options a., b., and d. are incorrect.

Conclusion

The ancestral characteristics are visible during the development of the embryo and the presence of notochord is the characteristic feature of chordates both invertebrates and vertebrates. Thus, the correct option is c.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
