Punnett Squares
What are the possibilities in getting a Homozygous Dominant trait in the crossing of: RR and Rr
50%
How many "parents" are needed in asexual reproduction
One
When will a recessive trait show up?
When only two recessive alleles are present/ no dominant allele is present
Tightly wound DNA builds what?
Chromosomes
Who is the father of genetics
Greger Mendall
I have a red and white flower that are being crossed with incomplete dominance. What percent of the flowers will be pink?
100%
What type of reproduction has more diversity and why?
Sexual; crossing of different DNA making new combinations
I have white, brown, and tan cows. The Tan cows result from incomplete dominance. What color parent cows should I use to breed for the next generation to be only Tan?
One white Cow and One Brown Cow
What are inherited traits? What are acquired traits?
Inherited: a trait you gain from your parents
Acquired: A trait you learn over time
What is Heredity (Definition)
The passing of characteristics from parents to offspring
I have two heterozygous peas coding for texture, with bumpy being dominant. When they cross, what are the chances I get a smooth off spring?
25%
What reproduction type has the fastest growth and why?
Asexual; the population can double in size in one year due to only needing one parent
If a chicken color is codominant and the following colors are available: Red, Grey, Brown, and Tan, how many different alleles are there for chicken color?
What is the definition of a trait?
specific characteristic or quality
Give an example of an Inherited trait and an example of a acquired trait
* SOOO many options here*
What are the three mechanisms that can be used to do asexual reproduction?
Binary Fission, Budding, Fragmentation
A homozygous recessive parent and a hybrid parent are crossed. What are all the genotype possibilities their offspring would have (show percentages)?
50%: Heterozygous (Rr)
50%: Homozygous recessive (rr)
What is a a Gene?
A section of DNA that contains certain traits
Where are chromosomes found?
In the Nucleus of a cell
I have two spotted cows. What are the chances of them having a spotted cow?
50%
Population a: Asexual reproduction
Population b: Sexual Reproduction
Which population is more likely to be harmed by environmental factors, and why?
Population A: Less diversity means they cannot adapt and overcome hardship. - If it affects a trait, they have all will die
An orange dragonfly resulted from two parents mating in a codominant cross. The parents have a phenotype of orange and pink. What genotypes would make this possible?
OP for both parents: 25% of all orange off spring
What is DNA? (not what does it stand for)
Genetic material that controls traits
How did ol' Greg figure out Punnett squares
He tracked the outcomes of crossing pea plants and the probability of the offspring inheriting specific traits
