A carrier of a trait controlled by a ❌ allele ❌ have the trait.
The carrier of a recessive allele can pass it on to their offspring
Sex linked genes can have only dominant alleles
Genes on the X and Y chromosomes are often called...
Dominant alleles
Recessive alleles
Sex-linked alleles
Sex- linked genes
Females have only X chromosomes, Y Chromosomes( X chromosomes,, Y Chromosomes ) but males have both and X and a Y. X and and X( X and a Y., X and and X )
Which one is not one of the three patterns of inheritance in humans?
Single Gene with Two Alleles
Single Genes with Multiple Alleles
Traits controlled by many genes
Traits by controlled by a single gene with no alleles
How many human blood types are there ?
4 A,B,AB,O
4 A,B,C,D
4 A,B,AB,BA
3 A,B,o
the ❌ carry genes that determine wether a person is ❌ and carry genes that determine other traits
A person's characteristics are determined only by genes
Colorblindness is a trait controlled by a ❌ allele on the ❌ chromosome.
A carrier is a person who has one recessive allele dominant allele( recessive allele, dominant allele ) for a trait and one dominant allele. dormant gene( dominant allele., dormant gene )
The two causes of genetic disorders in humans are mutations in the ❌ of genes and changes in teh overall structure or number of ❌s.
Genetic disorder that makes the body produce abnormally thick mucus in the lungs and intestines.
SIckle Cell disease
Cystic Fibrosis
Hemophilia
One important tool that geneticist use to trace the ❌ in humans is a ❌ or family tree.
Down Syndrome is when a person's cells have an extra copy of .
Today doctors use karyotypes pedigree genotypes( karyotypes, pedigree, genotypes ) to help diagnose genetic disorders
What is the genetic cause of cystic fibrosis?
Loss of 3 DNA bases
Adding 3 DNA bases
Loss of 2 DNA bases
An examle of a human trait that is controlled by more than one gene is
blood type
skin color
widow's peak
dimples
A person who has one recessive and one dominant allele for a trait is called a
homozygote
carrier
clone
hybrid
A genetic disorder in which the person's blood clots very slow if at all is
sickle cell disease
cystic fibrosis
down's syndrome
hemohilia
The crsossing of two individuals that have similar characteristics is referred to as
genetic engineering
hybridization
inbreeding
cloning
The transfer of genes from one organism to another is called
selective breeding
A chart that tracks which members of a family have a particular trait is called a
pedigree
Punnett Square
karyotype
genome
In a pedigree, a square is used to represent a
female
male
The sex multiple recessive gene( sex, multiple, recessive, gene ) chromosomes determine if a person is a male or female
An abnormal condition that a person inherits through genes or chromosomes is a
gene therapy
genetic disorer
Three or more forms of a gene that code for a single trait are called multiple alleles
Sex-linked recessive traits are more common in females
Sickle Cell disease is a genetic disorder in which the body produces abnormally thick mucus.
The process of selecting a few organisms with desired traits to serve as parents of the next generation is called genetic engineering
In karyotyping a person's DNA is cut into fragments, which are separated to form a pattern.
A(n) genome clone( genome, clone ) is all the DNA in one cell of an organism.
The goal of the ❌ has been to identify the DNA sequence of every human gene
A ❌ is an organism that is genetically identifcal to the organism from which it was produced.
Why is hemophilia more common in males?
Sex linked trait on the X chromosome
Sex linked trait on the Y chromosome
Recessive trait on the Y chromosome
Dominant trait on the Y chromosome
A couple has a son who does not have symptoms of sickle-cell disease has no chance of having abnormal hemoglobin
3 methods that people have used to produce plants and animals with desireable traits include
The Human Genome Project, selective breeding and cloning
Cloning, selective breeding, and genetic engineering
Karyotype, cloning, selective breeding
Which parent basically controls the trait for colorblindness for the sons?
The father, because he has the Y chromosome?
The mother, because the trait is passed on the X chromosome
It could be either, because it is a recessive allele
Only the female male( female, male ) gender can be a carrier of a sex-linked trait.
