2
Particulate inheritance
________ is that the hereditary determinants for traits do not blend together or become modified through use.
New cards
3
Polygenic
________ is where each of many different genes adds a small amount to the value of the trait.
New cards
4
unusual phenotype
An individual with a(n) ________ due to a mutation is referred to as a mutant.
New cards
5
model organism
A(n) ________ is a species that is used for research because it is easy to work with and conclusions drawn from studying it may apply to many other species.
New cards
6
Environmental effects
________ are anything that influences phenotypes other than the genotype, including temperature, sunlight, nutrient availability, competition, and even a mothers hormone levels during development of an embryo.

7
molecular level
Phenotype can be any observable characteristic, from ________ aits such as protein shape to the familiar aits of entire organisms at Mendel studied.
New cards
8
Trait
Any observable characteristic of an individual, ranging from outward appearance such as height to molecular characteristics such as the prima structure of a particular membrane protein.
New cards
9
Self fertilization
________ occurs when a flower's pollen falls on the female reproductive organ of that same flower.
New cards
10
interaction
When two or more genes influence a single trait, it is called gene ________.
New cards
11
Epistasis
________ occurs when the expression of a phenotype associated with a particular genotype of one gene can be completely masked by a particular genotype of a different gene.
New cards
12
Hybrids
________ are offspring from matings between true breeding parents that differ in one or more traits.
New cards
13
genetic map
A(n) ________ is a diagram showing the relative positions (loci) of genes along a particular chromosome.
New cards
14
Mutation
________ is a heritable change in a gene.
New cards
15
Heterozygous individuals
________ who do not have an inherited disease but carry a recessive allele for it are called carriers of the disease.

16
gene
A(n) ________ on the Y chromosome is a Y- linked ________.

19
Pure line
consists of individuals that produce offspring identical to the parents when they are crossed to another member of the same pure-line population or are self-fertilized.
New cards
20
