Heredity and Reproduction

Heredity and Reproduction

Multiple Choice

Genotype

• the physical appearance of an organism

• the genetic makeup of an organism

• the alleles present in an organism

• a dominate trait

Multiple Choice

Phenotype

• the genetic makeup of an organism

• present only in offspring from asexual reproduction

• the physical appearance of an organism

• a recessive trait

Multiple Choice

A trait

• is a characteristic of an organism controlled by genetics

• is a trait of an organism not controlled by genetics

• is found in plants only

• is not genetically significant

Multiple Choice

Heterozygous

• expressed as BB,bb

• having two different alleles for the same trait

• having two of the same alleles for a specific trait

• is also known as a purebred

Multiple Choice

Alleles

• are found mainly in the mitrochondria

• are not part of genetics

• variations of a gene for the same trait

• are found only in prokaryotic organisms

Multiple Choice

Heredity is

• the passing of genetic information from one generation to the next

• the study of genetics

• a very fun subject

• the study of specific traits

Multiple Choice

A Punnett square

• is used for statistical purposes

• is used to predict the probability of offspring from specific pairs

• is always correct with outcomes

• is an excellent mathematical tool for genetics

Multiple Choice

A dominate trait

• comes only from hybrid alleles

• is a stronger, more desirable trait than a recessive trait

• is one that dominates or covers over another form of that trait

• is often not seen in the general population

Multiple Choice

A recessive trait

• comes from weak genes

• expresses dominate traits

• is a trait that is covered over or dominated by another form of that trait and seems to disappear

• is most commonly seen in the general population

Multiple Choice

DNA

• is not genetically important

• is found primarily in the cytoplasm

• does not contain significant genetic material

• an organic compound that is the genetic material of all organisms found inside the nucleus of a cell

Multiple Choice

Chromosomes

• are a structure in a cell's nucleus that contain genetic material

• are located inside the cell wall of plant cells

• only determine the gender of offspring

• are not genetically significant

Multiple Choice

Sexual reproduction

• produces identical offspring

• is a process involving two parents whose genetic material is combined to produce a new organism

• involves only one parent

• is a genetically faster process than asexual reproduction

Multiple Choice

Asexual reproduction

• is a process that involves two parents with diverse offspring

• is a genetically lengthy process

• is a process that involves one parent and produces genetically identical offspring

• produces both varied and identical offspring

Multiple Choice

Genetics is

• the study of reproduction

• the study of pea plants

• the study of heredity

• the study of ecology

Multiple Choice

Homozygous alleles

• have two of the same alleles for a trait

• may be represented by Bb

• have different alleles for a trait
