Vocabulary
100
This type of reproduction requires only 1 parents.
What is asexual reproduction?
100
Sexual reproduction requires this number of parents.
What is 2?
100
This tool helps scientists predict the possible traits of offspring.
What is a Punnett Square?
100
The passing of traits from parents to offspring.
What is heredity or inheritance?
100
Traits are controlled by sections of DNA called these.
What are genes?
200
Offspring produced this way are genetically identical to the parent.
What are clones?
200
In flowering plants, the male reproductive cell is found as a powdery substance.
What is pollen?
200
In a Punnett square, the letters represent different forms of a gene called these.
What are alleles?
200
This scientist is known as the “father of genetics.”
Who is Gregor Mendel?
200
This is the physical expression of a trait.
What is phenotype?
300
This is one disadvantage of asexual reproduction.
What is little or no genetic variation/diversity?
300
In flowering plants, the female reproductive cell is located inside this part of the flower.
What is the ovary?
300
A Punnett square showing Tt × Tt predicts this percentage of recessive offspring.
What is 25%?
300
If the alleles are the same, the organism is called...
What is homozygous?
300
The genetic makeup of an organism, such as RR or Rr, is known as this.
What is genotype?
400
This is one advantage of asexual reproduction.
What is reproduction happens quickly?
400
This process happens when pollen reaches the ovule and the reproductive cells combine.
What is fertilization?
400
What is the phenotype ratio of the following cross?
What is 3:1?
400
If the alleles are different, the organism is called...
What is heterozygous?
400
A characteristic of an organism, such as flower or eye color.
What is a trait?
500
Bacteria reproduce asexually using this process where one sell splits into two.
What is binary fission?
500
Sexual reproduction leads to this advantage in offspring, meaning they are not identical to their parents.
What is genetic variation/diversity?
500
What is the genotype ratio of the following cross?
What is 1:2:1?
500
A form of a gene that can only be expressed when two copies are present.
What is recessive?
500
Differences in traits among individuals in the same species, such as different eye colors or plant heights.
What is variation?
