Question 11
11.

TRUE OR FALSE: You get one allele for a trait from you mom, and one from you dad.

Question 12
12.

TRUE OR FALSE: Recessive alleles will only express a trait when there are NO dominant alleles.

Question 13

Fill in the blank: _________________ Alleles - An allele that covers another allele.

Question 14
14.

Fill in the blank: ______________________ Alleles - An allele that is covered, or hidden by another allele.

Question 15
15.

Which TWO of the following are correct?

Question 16
16.

Which of the following is the correct defintion of Genotype?

Question 17
17.

Which of the following is the correct defintion of Phenotype?

Question 18
18.

Question 19
19.

Question 20
20.

Select ALL the following staments that are true.

Question 21
21.

What is a punnett square?

Directions: Black is the DOMINANT fur color for rabbits and white is the recessive. B stands for the black allele and b represents the white allele. A white rabbit would have a genotype of bb and a black rabbit could have a genotype of BB or Bb.
Question 22
22.

A heterozygous tall (Tt) pea plant with a heterozygous tall (Tt) pea plant were crossed. Note: tt indicates a short plant. The punnet square is below. What are the correct ratios and percentages of the offspring's genotypes?

Question 23
23.

A heterozygous tall (Tt) pea plant with a heterozygous tall (Tt) pea plant were crossed. Note: tt indicates a short plant. The punnet square is below. What are the correct ratios and percentages of the offspring's phenotypes?

Question 24
24.

Which of the following is true about Melanin

Question 25
25.

List eye colors from the greatest to least amount of Melanin in the iris

  1. Brown
  2. Hazel
  3. Green
  4. Blue
Question 26
26.

Down's Syndrome is a chromosomal disorder resulting from nondisjunction of the 21st chromosome and is equally common among those of any race or genetic background.

It involves crossing over between chromosomes which makes independent assortment of alleles possible
It makes sexual reproduction possible
It allows bacteria to reproduce asexually.
Select ALL of the follwoing that are true about Sexual Reproduction.
offspring are unique and look different from parents
offspring is produced by only ONE parent
specific forms include budding, fragmentation, and binary fission
offspring is produced by TWO parents genetically combining
fish, amphibians, and mammals can reproduce this way
it is more time intensive
bacteria, yeast, hydra, and flatworms can reproduce this way
genetic variation from the parent can also come from mutations in the DNA of the offspring
Select ALL of the following that are true about Asexual Reproduction.
bacteria, yeast, hydra, and flatworms can reproduce this way
genetic variation from the parent mostly comes from mutations in the DNA of the offspring
organisms who reproduce this way can reproduce in as little as 20 minutes
specific forms include budding, fragmentation, and binary fission
fish, amphibians, and mammals can reproduce this way
offspring are identical to their parents
offspring is produced by only ONE parent
offspring is produced by TWO parents genetically combining
describes most cells in our bodies, having two pairs of each chromosome
diploid
the cell formed when a sperm fertilizes an egg
pigment
the growing mass of cells as a zygote increases in size through mitosis
embryo
substance like chlorophyll or melanin that can absorb some colors of light
Select ALL the following that are examples of a Genotype.

Short Stem
Freckles
Blue Eyes
GG
Select ALL the following that are examples of a Phenotype.
Bb

aa
Red Eyes
Dimples

If the two alleles are the same, its Genotype is homozygous
If the two alleles are different, its Genotype is heterozygous
