Punnett Squares
Surprise!
100
Number of parents in asexual reproduction.
What is one?
100
This occurs before either meiosis or mitosis can begin.
What is the DNA is copied?
100
The alleles of a parent that is heterozygous
What is Hh
100
The purpose of a Punnet Square.
What is to find the probability of the outcome of a genetic cross?
100
Flowering plants reproduce this way.
What is sexual reproduction?
200
How offspring compare to parents in sexual reproduction.
What is offspring are different from parents?
200
This is the end result of mitosis.
What is two daughter cells that are identical to the parent cell?
200
Definition and example of homozygous and heterozygous.
What is homozygous is when the alleles are the same such as TT or tt and heterozygous is when the alleles are different such as Tt?
200
The outcome of a cross between Tt and tt.
What is 50% or 2/4 Tt and 50% or 2/4 tt?
200
The process when pollen contacts the stigma
What is pollination?
300
An advantage of sexual reproduction.
What is genetic diversity?
300
This is the result of meiosis.
What is four gametes that are unique?
300
Definition of genotype and phenotype.
What is genotype is genetic make-up and phenotype is the physical expression of the genotype?
300
The outcome of a cross between Tt and Tt.
What is 75% or 3/4 dominant and 25% or 1/4 recessive?
300
The process when an egg cell and a sperm cell join together, creating a new cell called a zygote
What is fertilization?
400
An advantage of asexual reproduction.
What is it is quick, doesn't take a lot of energy, and it only requires one parent?
400
Two similarities between meiosis and mitosis.
What are they both copy the DNA, dissolve the nucleus, line chromosomes up in the middle of the cell, pull chromosomes to either side of the cell, and divide to make the new cells.
400
Definition of dominant and recessive traits.
What is a dominant trait will show up if a dominant allele is present but a recessive trait will show up only if there are TWO recessive alleles?
400
The outcome of a cross between TT and tt.
What is 100% dominant?
400
The relationship between genotype and phenotype.
What is genotype determines the phenotype?
500
Two examples of asexual reproduction.
What are vegetative propagation, binary fission, budding, or regeneration?
500
The purpose of mitosis for unicellular and multi-cellular organisms.
What is unicellular it's for reproduction and multi-cellular it's for growth or repair?
500
Assume a parent is heterozygous. Explain whether the dominant allele is easier to inherit than the recessive one.
What is each allele has a an equal chance of being inherited? Dominant will overwhelm recessive but the alleles have equal chances.
500
The parents of this Punnett square.
Heterozygous (Gg) and Homozygous recessive (gg)
500
Koalas have 8 chromosomes in their gametes, how many chromosomes do they have in their body cells?
What is 16 chromosomes?
