Which of these claims is true of sexual reproduction?
It requires two parents and results in offspring that have characteristics of each parent.
It requires one parent and results in offspring that are genetically identical.
It requires two parents and results in offspring that are genetically identical to one parent.
If an organism is produced by sexual reproduction, which of these claims is true of its chromosomes?
It receives all of its chromosomes from its female parent.
It receives half of its chromosomes from each parent.
It receives most of its chromosomes from its male parent.
Amanda is making a poster in science class to describe two types of cell division. She wants to show diagrams of mitosis and meiosis zooming out from different parts of the body where they take place.Which correctly shows a location for a type of cell division.
Bone-meiosis
male sperm- mitosis
female ovaries/egg- meiosis
stomach-meiosis
Sean is studying fungi in his lab.Each fungus produces specialized cells that develop into new, multi cellular organisms that are genetically identical to the parent organism. What does the process demonstrate?
sexual reproduction
asexual reproduction
fertilization
Look at the diagram. The alleles for parents are missing. The parents have which of these alleles.
DD and Dd
Dd and dd
DD and dd
Dd and Dd
Having attached or unattached earlobes is an inherited trait. Attached earlobes occurs in individuals with the genotype ee. What is the relationship between an individual's chromosomes and the genes for earlobe attachment?
The genes for earlobe attachment are located on the chromosomes for each cell.
The chromosomes for earlobe attachment are located on the genes for each cell.
Mitosis is the main mechanism of asexual reproduction. Cassie draws flashcards for each phase of mitosis and the cell cycle. Before she can label the backs of the flashcards, Cassie drops them onto the floor. The flashcards get mixed up as shown. In what order should Cassie place the cards to show mitosis and the cell cycle from start to finish?
1--> 2 -->3 -->4 -->5
2-->4-->5-->1-->3
3-->1-->5-->2-->4
The diagram shows the results of crossing a pea plant with round seeds and a pea plant with wrinkled seeds. What can be determined from the results of the experiment?
Smooth shape and wrinkled shape are both recessive traits.
Smooth shape and wrinkled shape are both dominant traits.
Smooth shape is a dominant trait, and wrinkled shape is a recessive trait.
Smooth shape is a recessive trait, and wrinkled shape is a dominant trait.
Delia is teaching her sister about important molecules in the body. She tells her sister that one molecule provides a set of instructions that determines traits, such as eye color or hair color. Which molecule is Delia describing?
DNA
glucose
cellulose
Look at the pedigree chart. What can be inferred regarding the genotypes of parent 3 and 4 based on the resulting offspring?
Both parents have to be heterozygous.
One parent is heterozygous and one parent is homozygous recessive.
One parent is heterozygous and one parent is homozygous dominant.
In his laboratory, Jin is studying the genetics of mice. For a particular trait, an adult female mouse has the alleles AA, and an adult male mouse has the alleles Aa. Complete a punnett square and select the possible outcome of the offspring if they were to mate.
50% Aa and 50% aa
100% Aa
50% Aa and 50% AA
75% Aa and 25% aa
There are two main types of cells in the human body. Some cells are body cells. Other cells are sex cells. The sex cells are involved in transmitting genetic information from parents to offspring. Which of these statements describes a characteristic of a sex cell?
It makes up most tissues.
It has twice the chromosomes of a body cell.
It contains half the chromosomes of a body cell.
Maribel is making a list of advantages to each type of reproduction: asexual and sexual. To help her out select all of the advantages to organisms reproducing asexually.
It does not require two individuals.
It takes shorter amount of time to reproduce.
It results in genetic diversity among offspring.
It requires a male and a female.
Terrie is making a model of DNA. Which of these shapes illustrates how her model should look?
