Summary Introduction

Introduction:

Reptile eggs are called as the amniotic egg after fertilization. It consists of four layers called as allantois, amnion, chorion and yolk-sac. The embryo develops inside the fertilized egg in a watery environment.

Expert Solution & Answer

Answer to Problem 1MC

Correct answer:

In a reptile egg, the extra embryonic membrane that encloses the embryo in a watery environment is the amnion.

Therefore, option (b) is correct.

Option (b) is given as “amnion”.

Explanation of Solution

Justify reasons for the correct statement:

Amnion layer encloses the fertilized embryo in a watery environment containing the amniotic fluid. It gives protection during the stages of development of the egg. It forms the ectoderm, mesoderm and endoderm during the fertilization of the egg.

Hence, option (b) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “allantois”.

Allantois forms separate sac which secretes the metabolic wastes from the human body. Hence, it is a wrong answer.

Option (c) is given as “chorion”.

It is present near the egg shell and helps in the exchange of gases like oxygen and carbon-dioxide. Hence, it is a wrong answer.

Option (d) is given as “yolk-sac”.

It contains the egg yolk. Hence, it is a wrong answer.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

Reptile amniotic eggs contain amnion layer with watery environment which prevents the egg under shock and stress.

Your goal is to produce black seeds resistant to mold. So you make the same cross again (between a homozygous black seeded, mold susceptible parent and a homozygous white seeded and mold resistant parent), and, again, advance progeny by SSD to create 100 F10 generation plants. Based on the information you obtained from your first crossing experiment (Question #4), how many F10 plants would you expect to have black seeds and be resistant to mold? Assume that a toxin produced by the mold fungus has been isolated. Only mold resistant seeds will germinate in the presence of the toxin. Could you use this toxin screening procedure to have segregation distortion work in your favor in the F2 generation? Explain your answer. Info from Question 4 a. P Locus (Seed Color): Hypothesis: The null hypothesis (H₀) is that seed color is controlled by alleles at a single locus.

Using Punnett Squares Punnett squares are one good way to predict the outcome of genetic crosses. Punnett squares use mathematical probability to help predict the genotype and phenotype combinations in genetic crosses. The number of possible alleles from each parent determines the number of rows and columns in the Punnett square. Independent Assortment KEY QUESTION How do alleles segregate when more than one gene is involved? Mendel wondered if the segregation of one pair of alleles affects another pair. For example, does the gene that determines the shape of a seed affect the gene for seed color? This type of experiment is known as a two-factor, or dihybrid, cross because it involves two different genes. Single-gene crosses are monohybrid crosses.
