The visible or measurable features of an individual refers to _____. - - ANS✔️--phenotype
How many chromosomes are in a human sperm? - - ANS✔️--23
An allele that reveals itself in the phenotype only if the organism has two copies of that allele is a
_____ allele. - - ANS✔️--recessive
If sickle-cell anemia is present in some of your family members, what is some information you
could obtain from reading about the research that has been done on the condition? - - ANS✔️--all
of these
A person has a cystic fibrosis phenotype. What does this mean about the protein encoded by the
cystic fibrosis gene in his or her cells? - - ANS✔️--the protein is not functional
The principle that alleles of different genes are distributed independently of one another during
meiosis is _____. - - ANS✔️--independent assortment
,Albinism is a genetic condition where a person lacks (melanin) pigmentation in his or her skin,
hair, and eyes. If two nonalbino people have a child who exhibits albinism, this means albinism
is most likely a _____ trait. - - ANS✔️--recessive
Which body system has been discovered to have the most genes that influence the severity of
CF? - - ANS✔️--immune system
A gene encodes a protein of 350 amino acids. A mutation creates an allele that only has the first
120 amino acids. What could happen to this mutant allele? - - ANS✔️--all of these
A meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes.
If that egg is fertilized by a normal sperm, how many chromosomes will be in the zygote? - -
ANS✔️--47
Mexican hairless dogs are hairless because of a dominant allele of a particular gene.
Homozygous dominant dogs die in utero (before being born). What is the probability of two
hairless dogs having a hairy puppy? - - ANS✔️--1/4
What type of trait would you assume polydactyly (extra fingers or toes) is when every member
of the family who has one dominant allele exhibits polydactyly. - - ANS✔️--dominant
, Allele A has 235 codons. Allele a (an alternative allele of the same gene) has 233 codons. When
comparing the protein encoded by allele A to that encoded by allele a, protein A must be: - -
ANS✔️--longer by 2 amino acids
