Exam 13: Genetics

In a cross between a long and a globe-shaped radish, the F₁ generation consisted of 247 oval-shaped radishes. The F₂ generation consisted of 62 long radishes, 127 oval radishes, and 59 globe-shaped radishes. Which of the following pertaining to this cross is true?

An anticodon is found on a molecule of

Assume the same cross as in question 29. How many different kinds of genotypes would occur in the F₂ generation?

The British biologists who first reported linkage in sweet peas were

If all cells of a plant have identical DNA, then why are there different cell types and tissues within a plant?

The process of producing an accurate DNA copy of the genome is referred to as ________.

Chromosomal mapping primarily involves

Which of the following describes the function of DNA in a cell?

The law of independent assortment is illustrated only in monohybrid crosses.

The sum total of DNA in an organism's chromosomes constitutes the ________.

Mendel's law of unit characters says that the inheritance of characteristics is controlled by factors that always occur in pairs.

The most significant cause for exceptions to the Hardy-Weinberg law is

Alternate forms of the same trait (yellow seeds or green seeds) are called

________ is the study of chromosome behavior and structure at the cellular level.

In a variety of cornflowers in which blue flowers and dwarf plants are controlled by dominant genes carried on separate pairs of chromosomes, and white flowers and tall plants are their recessive counterparts, assume a cross has been made between a homozygous blue, dwarf plant and a homozygous white, tall plant. Which of the following would be represented in the F₁ generation?

The pinpointing of relative locations of genes on chromosomes CANNOT be brought about by calculating percentages of crossing-over in large populations.

What is the correct genotype of a homozygous dihybrid individual having dominant phenotypes for both traits?

Which statement about transposons is INCORRECT?

If a pure breeding parent producing yellow seeds, the dominant phenotype, is crossed with a pure breeding parent producing green seeds, the recessive phenotype, the F₁ generation will produce

Mendel discovered the rules of inheritance only after the discoveries of chromosomes and meiosis.
