A trait that is not passed down from parents to their offspring . acquired trait
Dyed hair, pierced ears, broken bones, and scars are examples of a(n)__________. acquired trait
reproduction in which one parent produces offspring without fertilization of an egg cell asexual reproduction
offspring have the same genetic makeup as the parent asexual reproduction
traits that are both seen when they are present codominant trait
a chicken with black and white feathers is an example codominant trait
a trait that is always visible in offspring whenever it is present; blocks the other genetic trait dominant trait
when dominant and recessive traits are present, this is the only trait visible dominant trait
a new living thing produced by one or two parents offspring
a trait that is not seen when the dominant trait is also present; it is the trait blocked or masked recessive trait
reproduction when two gametes are present; the sperm and egg cells sexual reproduction
a cell with half the chromosomes of a diploid cell haploid cell
sex cells; sperm and egg cells gametes
a characteristic of an organism trait
skin color, eye color, hair, allergies, face shape, and many others inherited traits
one of two or more forms that a gene could take allele
describes an allele that is always expressed when it is present dominant trait
a pattern of inheritance in which the phenotypes of both alleles inherited are clearly expressed codominance
the genetic make of an organism genotype
having two alleles that are different heterozygous
Rr heterozygous dominant
rr homozygous recessive
RR homozygous dominant
having two alleles that are the same homozygous
the physical appearance of an organism phenotype
the likelihood that a specific event will occur probability
a diagram that shows the possible genotype of offspring two parents Punnett square
decribes an allele that is not expressed when the dominant allele is present recessive trait
when an experiment is concluded trial
uppercase letters represent this allele dominant
lowercase letters represent this allele recessive
During a first generation cross the offspring will be _______________. hybrids
Heterozygous is also called _________________. hybrid
Homozygous dominant and homozygous recessive also known as purebreeds
During a second generation cross hybrid cross
The phenotype result of a second generation cross 3 to 1 75% chance of dominate offspring
The genotype result of a second generation 1 to 2 to 1 Homozygous dominant: heterozygous: homozygous recessive DD -Dd- dd
An example of sex linked trait colorblindess
an example of incomplete dominance red and white flower make pink offspring
an example of dominant trait black mouse fur hides the white fur
example of recessive trait white fur is hidden by black fur
A genetic disorder is shown two recessive traits are present
