Passing of genetic traits from parent to offspring

Likelihood of a future event happening

What is a dominant trait?

The trait observed in the first generation when parents that have different traits are bred.

One set of instructions for an inherited trait

Entire genetic makeup of an individual

What is a recessive trait?

Trait that is apparent only when two recessive alleles for the same characteristic is inherited.

One of the alternative forms of a gene that governs a characteristic, such as hair color.

The entire genetic makeup of an organism.

Crossing of like traits to produce a true bred

The trait observed in the first generation when parents that have different traits are bred.

The entire genetic makeup of an organism.

Result of a crossbred self pollination

What is cross pollination?

When a plants can fertilize itself

Offspring of a self pollinating plant - all plants will have the same traits as the parents and siblings

Offspring from the cross pollination

Offspring of a foster plant pollinating another offspring

What is self pollination?

When a plants can fertilize itself

Offspring from the cross pollination

What is a cross-bred?

Offspring from the cross pollination

Offspring of a self pollinating plant - all plants will have the same traits as the parents and siblings

Offspring of a hybrid self pollinator

Genes are made up of two alleles, one of which is “ stronger ” and the other is “ weaker ”. What does “ weaker ” refer to?

Doesn't show up often in the gene pool

Below is a diagram sketched out in a research scientist's journal. It shows a cell during Meiosis I. The scientist chose to sketch two different images showing the different ways chromosomes could possibly line up in the parent cell during Metaphase I. What is significant about the stage of Meiosis I that the scientist had sketched in their journal?

It allows for the formation of new allele combinations in a gamete.

It allows the cell to maintain the same amount of DNA in the daughter cells.

It causes gene mutations which lead to disease in the offspring of the individual.

Which of the following could result if meiosis did not occur in the process of sexual reproduction?

Chromosome number would increase with each generation.

Chromosomes would no longer contain genetic information.

Chromosomes would not be copied exactly.

Chromosome number would decrease with each generation.

Compared with mitosis, the process of meiosis results in daughter cells that are-

haploid cells with a smaller number of chromosomes than the parent cells

diploid cells with the same number of chromosomes as the parent cells

diploid cells with a smaller number of chromosomes than the parent cells

haploid cells with the same number of chromosomes as the parent cells

About

This quiz comprehensively covers fundamental genetics concepts appropriate for grades 11-12, focusing on inheritance patterns, meiosis, and genetic terminology. The questions progress from basic vocabulary definitions (genes, alleles, phenotype, genotype) through increasingly complex applications including Mendelian inheritance, sex-linked traits, non-Mendelian patterns like incomplete dominance and codominance, and chromosomal abnormalities. Students need a solid understanding of dominant and recessive alleles, the ability to work with Punnett squares and probability calculations, knowledge of meiosis and its role in genetic variation, and familiarity with sex-linked inheritance patterns. The quiz also requires students to distinguish between different inheritance patterns such as complete dominance, incomplete dominance, and codominance, while applying concepts like independent assortment and the significance of chromosomal nondisjunction events. Created by David Atwood, a Biology teacher in the US who teaches grades 11-12. This comprehensive review quiz serves as an excellent tool for reinforcing genetics concepts before the AP Biology exam, making it ideal for formative assessment, homework assignments, or as a comprehensive review session after completing Unit 5. Teachers can use this quiz to identify knowledge gaps in student understanding, assign it as independent practice, or implement it as a warm-up activity spread across multiple class periods. The quiz effectively supports classroom instruction by covering key topics that align with AP Biology standards, including patterns of inheritance, meiosis and genetic diversity, and gene expression. This assessment tool helps students prepare for both the conceptual understanding and application skills required for success on the AP Biology examination.
