in a pair that occupy the same site and code for the
same genetic trait.
What are the two types of Dominant and recessive.
alleles?
When is a recessive allele When both alleles are recessive.
expressed in the
phenotype?
How is a dominant allele With a capital letter.
represented in genetic
notation?

represented in genetic
notation?
What does homozygous A pair of alleles that are either both dominant or both recessive.
mean in genetics?
What is an example of a BB or bb.
homozygous genotype?
What does heterozygous An allele pair in which one is dominant and one is recessive.
mean in genetics?
What happens in autosomal Both alleles on the chromosome are affected by the genetic
recessive disorders? aberration.
What is a carrier in the A person with one affected recessive gene who does not express
context of genetic diseases? the disease phenotype.
,What is the role of a It compensates for the affected allele, preventing
healthy recessive allele phenotypic expression of the disease.
in a carrier?
What is required for Only one dominant gene must be affected by the genetic
phenotypic expression of an aberration.
autosomal dominant
disorder?
What is the significance of It helps determine the possible genotypes of offspring
drawing a Punnett Square based on parental genotypes.
in genetics?
What is the genotype of a aa.
husband with an autosomal
recessive disease?
What is the genotype of a wife Aa.
who is a
carrier for an autosomal
recessive disease?
What is the probability 50%.

express the autosomal
recessive disease if one
parent is aa and the other is
Aa?
What genetic concept is Sex-linked disease.
exemplified by a child
diagnosed with
hemophilia?
What is the difference Phenotype is the expression of a genetic disease, while
between phenotype and genotype refers to a gene's programming.
genotype?
How is hemophilia Hemophilia is transmitted on the X-chromosome and not via the
transmitted? autosomes.
What physiological Dehydration triggers increased secretion of renin.
response is triggered by
dehydration?
What happens to antidiuretic There is a decreased secretion of antidiuretic hormone during
hormone levels during dehydration.
, dehydration?
What is the significance of Decreased serum osmolality is not typically associated
decreased serum with dehydration; instead, dehydration usually leads
osmolality in dehydration? to increased serum osmolality.
