Sponges reproduce by a process known as budding. This process is the formation of a new individual that is a clone of the parent. This type of reproduction is __________.
results in low genetic variation of the species
What would be a possible disadvantage of the type of reproduction shown in the diagram above?
Which of the following is the correct organization of genetic material from smallest to largest?
A. DNA, genes, chromosomes, cell nucleus
B. genes, chromosomes, DNA, cell nucleus
C. cell nucleus, genes, DNA, chromosomes
D. chromosomes, DNA, cell nucleus, genes
What structure is the arrow pointing to in the diagram?
Gregor Mendel discovered that every trait is determined by two alleles. he noted that the pair of alleles from each parent separates and their offspring will inherit only one allele from each parent. This discovery became known as __________ __________.
the ability to tongue roll is a dominant trait
The ability to roll your tongue is an inherited trait. There are more people who can roll their tongues than people who can't roll their tongues. What assumption can be used to explain this?
BB, Bb, bb
In humans, eye color and hair color are controlled by several genes. Assume that each is controlled by only one gene. For eye color, brown (B) is dominant over blue (b) and for hair color, black (H) is dominant over blonde (h). A male with blue eyes produces offspring with a female that has brown eyes. The genotype of the Father could be ______ or ______. The genotype of the Mother would be ______.
Bb, Bb, Bb, Bb
In humans, eye color and hair color are controlled by several genes. Assume that each is controlled by only one gene. For eye color, brown (B) is dominant over blue (b) and for hair color, black (H) is dominant over blonde (h). A male with blue eyes produces offspring with a female that has brown eyes. What would be the possible genotypes for eye color for the offspring if the Father is BB and the Mother is bb ? Hint: make a Punnett square.

For eye color, brown (B) is dominant over blue (b) and for hair color, black (H) is dominant over blonde (h). A male with blue eyes produces offspring with a female that has brown eyes. The genotypes for hair color for the parents are: Father (hh) and Mother (Hh). Which Punnett square above represents the possible genotypes for hair color for the offspring?
An offspring inherited a dominant allele from one parent and a recessive allele from the other parent for the same trait. In the picture above which is a possible explanation for what will be exhibited by the offspring for that trait?
Sexual reproduction -
How many genes does an offspring receive for each trait?
I and II
The diagram represents different processes involved in reproduction. Which diagrams represents sexual reproduction.
The work of Gregor Mendel was based on his discovery that heredity information for two different forms of a trait can coexist in one individual. He recognized that one form of the trait masks the expression of the other. This principle is known as the law of __________.
Heredity is defined as the passage of genetic instructions from one generation to the next. Which of the following is not an example of these genetic instructions in humans?
height, skin color, dimples, or spoken language
__________ is the passing of traits from parent to offspring.
The different forms of a trait that a gene may have are called __________.
The study of how traits are inherited through the interaction of alleles is called __________.
Who is the Austrian monk who studied mathematics and science but became a gardener in a monastery?
Mendel is known as the __________ of __________.
An organism that always produces the same traits generation after generation is called __________.
In one of Mendel's experiments he crossed a tall pea plant with a short pea plant and all of the offspring were tall. This process is called __________-__________.
A handy tool used to predict results in Mendalian genetics is the __________ __________.
In a Punnett square, a capital letter represents a __________ allele.
In a Punnett square, a lower-case letter represents a __________ allele.
When an organism has two alleles that are the same, for instance (TT) or (tt) the alleles are said to be __________.
When an organism has two alleles that are different, for instance (Tt) the alleles are said to be __________.
The letters in a Punnett square are a form or code that show the __________, or genetic makeup, of an organism.
The way an organism looks and behaves as a result of its genotype is its __________.
