Gametes may carry different combinations of alleles because of

A desert plant called Kalanchoe can reproduce, either with sexual reproduction through flowers, or asexually by budding off miniature leaf and root clusters from its leaves. When buds are produced, they land on the ground, take root, and grow, genetically identical to the original. If budding is used for several years, a large area may be covered with these descendents from the same original plant. The resulting population of plants will

Diploid (2n) means having

Mendel kept detailed records of the genetic traits of parent plants and their offspring plants. Among observations, he found that some traits were not expressed, whenever one particular allele was present. These masked traits can be referred to as

A cell with two full sets of chromosomes would be termed a_________ cell.

The process by which DNA is reproduced, with the use of associated enzymes, is

In a molecule of DNA, hydrogen bonds hold together the two strands, such as hydrogen bonds that form when

A researcher collected a single-celled organism from birdbath water and grew the organism in a laboratory. The researcher observed the organism reproducing by cell division, which resulted in identical offspring generations. This organism exhibits a form of

Scientists have developed an ointment to decrease muscle inflammation after intense workouts or trainings. To test the product, 99 weight lifters are divided into three equal groups. Group 1 is given the actual ointment, Group 2 is given an inactive ointment that looks and smells like the active ointment, and Group 3 is not allowed to use any treatment. Group 2 has been given
