Title: What is the relationship between a genotype and a phenotype Answer: Genotype describes the Genes tha


1
What is the relationship between a genotype and a
phenotype? Answer Genotype describes the Genes
that code for the Proteins, that make-up the
Phenotype.
2
What is the relationship between heterozygous and
homozygous?Answer Both Heterozygous and
Homozygous describe genotypes.AA,aa
HomozygousAa - Heterozygous
3
What is the relationship between genes and
traits?Genes code for the Proteins that make-up
the Phenotypes that show for a Trait.
4
A male heterozygous for size and color is crossed
with a female homozygous recessive for size and
homozygous dominant for color.
  • A small B blonde
  • a large b green

1.) How many traits are there in each organism?
22.) How many phenotypes will show in an
organism? 23.) Complete the cross between the
two organisms.4.) What is the chance of the
organisms producing an offspring that is
homozygous recessive for both size and color?
05.) What is the chance of these organisms
producing an offspring that is blonde? 100
5
Why is it important that all organisms only pass
on one gene per trait?What would most likely
happen to the offspring that received the wrong
number of genes?Most genetic mistakes (too many
or too few genes) wouldnt be able to live (the
fertilized egg wouldnt develop into a new
organism).
6
Put the following words into one of three
categories Describes Genes, Describes Looks,
Describes Both
  • genotype, phenotype, heterozygous, recessive,
    homozygous, dominant, trait, blonde, number of
    arms, Punnett square, genetic material, nature

Answer Genes genotype, heterozygous,
homozygous, genetic material Look phenotype,
trait, blonde, number of arms Both recessive,
dominant, Punnett square, nature
7
An organism has both eye color (red and yellow)
and number of teeth (18 and 36). If an organism
is heterozygous for both traits, yellow and 36
would show.An male organism that is
heterozygous for color and homozygous recessive
for number of teeth is mated with a female that
is heterozygous for both.
  • 1.) How many genes are there in each organism? 4
  • 2.) How many genes would each organism pass on to
    its offspring? 2
  • 3.) Complete the Punnett square for these
    offspring.
  • 4.) What is the chance of these parents producing
    a homozygous recessive offspring for both traits?
    1/8 or 2/16 or 12.5
  • 5.) What is the chance of having an offspring
    that is homozygous dominant for teeth? 0

8
An organism has foot size (small/big), body hair
(bald/hairy), and color of spots (red/yellow) for
physical features.If an organism is homozygous
dominant, small feet, hairy, and yellow spots
will show.A small, bald, red organism is mated
with a big, hairy, red female.
  • 1.) How many traits are there for these
    organisms? 3
  • 2.) List two possible genotypes of the female.
  • ff (foot size), hh (hair), rr (color)
  • 3.) List two possible genotypes of the male.
  • FF or Ff (foot size), HH or Hh (hair), rr (color)
  • 4.) Without doing a Punnett square, describe why
    these parents can expect 100 red offspring.
  • No parent even has a dominant gene to pass on to
    an offspring that would code for Yellow.

9
An organism has the following genes GHMFDBLA
  • 1.) How many genes per trait do all organisms
    pass on to their offspring? 1
  • 2.) How many traits does this organism have? 1
  • 3.) List three combinations of sex cells that
    this organism could produce.
  • GMDL
  • GFDA
  • And many others (as long as a letter isnt
    repeated)

10
A woman has the genes that make her short
tempered, but she lives in a town that does not
allow her to act angry. So, she acts like
everyone else and you would never know that she
is controlling her temper.Which part of the
above situation represents nature and which part
represents nurture? Explain your
answer.AnswerNature Genes that code for short
temperNurture Town controlling how she behaves.
