BSC 1005 EXAM 3
______ is the trait most commonly found in nature - ANSWERS-wild
type
true-breeding plants ---- - ANSWERS-self-fertilize to produce
offspring identical to the parent
the mating between a pedigree chihuahua and a great dane would
produce a - ANSWERS-hybrid
what are alleles - ANSWERS-alternate forms of a gene
a true breeding plant that produces yellow seeds is crossed with a
true-breeding plant that produces green seeds. all of the seeds of all of
the offspring are yellow. Why? - ANSWERS-the yellow allele is
dominant to the green allele
what is the expected phenotypic ratio of seed color of the offspring -
ANSWERS-3:1
according to mendel's principle of segregation - ANSWERS-gametes
have one copy of each allele
, attached earlobes are recessive to free earlobes. what genotypic ratio
is expected when an individual with attached earlobes mates with an
individual heterozygous for free earlobes? - ANSWERS-1:1
attached earlobes are recessive to free earlobes. what phenotypic ratio
is expected when an individual with attached earlobes mates with an
individual heterozygous for free earlobes? - ANSWERS-50&
what is the phenotype of an individual who is heterozygous for
dimples - ANSWERS-Dd
what name is given to the specific location of a gene on a
chromosome - ANSWERS-locus
an individual who is homozygous - ANSWERS-carries two copies of
the same allele for a gene
which of these crosses will only produce heterozygous offspring -
ANSWERS-AAxaa
an individual with the genotype AaBb produces four different gametes
in equal proportions. this is a demonstration of _____ - ANSWERS-
law of independent assortment
in order to determine the phenotype of an individual who expresses a
dominant trait, you would cross that individual with an individual
who is - ANSWERS-homozygous for that trait
