Asexual Reproduction - Sexual Reproduction
True or False - A paramecium that reproduces sexually is similar to its parents. - Explain why.
True - It is similar but not identical because two organisms of the same species are sharing their genetic material thus they cannot be identical to their parents.
This dating technique is done by scientists to figure out the chronological sequence of events.
What is relative dating?
A bird lives in the desert. What must the species do in order to adapt to the ever changing environment?
The bird must evolve.
B = Brown Dominant eye color
b= blue recessive eye color
Father has dominant brown eyes and he is heterozygous for brown eyes.
Mother is recessive for blue eyes and she is homozygous for blue eyes.
Make a Punnett Square and determine the probability of homozygous children with blue eyes.
50% of the children will have blue eyes.
If a family has a genetic disease which two statements are true. Write the statements on your whiteboard.
They pass down the disease through generations on the chromosomes
They are contagious
Everyone in the family has the disease
Some family members are just carriers of the disease
They pass down the disease through generations on the chromosomes
Some family members are just carriers of the disease
A Red Kangaroo reproduces using this type of reproduction.
Sexual Reproduction
Radiometric dating is also known as
What is Absolute Dating?
What is natural selection?
The process that makes evolution work. A process that makes an individual better suited to living in its environment.
Chin dimple = c recessive
No chin dimple (smooth chin)= C dominant
Mother has a chin dimple.
Father is homozygous and does not have a chin dimple (smooth chin).
Make a Punnett Square and determine the probability of children with dimples and without dimples.
All of the children are heterozygous and have smooth chins.
Asexual Reproduction.
True or False - A paramecium that reproduces asexually produces offspring that are identical to their parent. - Explain Why?
True - The binary fission method of asexual reproduction produces young that are identical to the parent. The genetic material is copied and is the same as the parent.
What is an adaptation?
A physical characteristic that allow organisms to successfully live in their environment.
Father is heterozygous for the square dominant head shape (S).
Mother is homozygous for the recessive round head shape (s).
Make a Punnett Square and determine the probabilities of all children.
50% of children are round (homozygous recessive) and 50% of children are square (Heterozygous dominant).
If a paramecium is similar to those of its parents which method was used for reproduction.
Sexual reproduction or conjugation.
What causes a paramecium to reproduce asexually?
Low amount of food.
There are three major types of rock. Name them.
What is igneous, metamorphic and sedimentary rock?
Define Evolution
The process of an organism changing and adapting over long period of time.
Mother and Father both have recessive blue eyes.
Make a Punnett Square and determine the probabilities for all children.
All children or 100% of children are recessive and have blue eyes.
How is a Karyotype used to help detect human genetic disorders?
When an organism reproduces by sexual reproduction it is said to
Conjugate
What is the age of the Earth in billions of years.
The Earth is 4.6 billion years old.
Long beak, short legs, black feathers, long wings, short tail are all examples of
What are adaptations?
Mother is homozygous for brown eyes.
Father is homozygous for brown eyes.
Make a Punnett Square - what percent of the children have blue eyes?
What is the definition of heredity?
The passing of traits or characteristics from one generation to the next generation through the process of reproduction.
