Traits & DNA
Explain what it means to inherit traits.
To pass genes from parent to child.
Heredity is the passing on of traits. Parents pass on their DNA to their offspring, which codes for the specific traits that offspring possess.
The offspring gets _____ the DNA from each parent.
Half, 23 Chromosomes each
Is the offspring identical (clone) or genetically different (unique)?
The offspring produced by Asexual is identical(clone)

What we call DNA when it is tightly folded up into a compact shape that we can see with a light microscope
A chromosome
The number of parents involved in sexual reproduction is...
two parents
The number of parents involved in asexual reproduction

Two things that sexual and asexual reproduction have in common
Offspring are created and DNA is passed down
What is the relationship between the terms chromosome, DNA, genes, and heredity?
The DNA is found in our Chromosomes. DNA and traits are related because DNA provides the code for traits. DNA is the set of instructions that determine your eye color, nose size/shape, skin color, and many other traits.
This is a form of sexual reproduction in plants. (Hint: Bees do it)
What is pollination?
What is one disadvantage of asexual reproduction?
No genetic variation, shorter lifespan, answers will vary
What type of reproduction can happen faster: sexual or asexual reproduction?
asexual reproduction
A section of DNA that contains the codes for a proteins traits
a gene
Are the offspring exactly the same or different from the parents? Why?
The offspring are different from the parents because they inherit DNA from both parents.
What are some advantages of Asexual Reproduction?
Fast process
No mate required

Whole group names traits. Answers will vary.
