Meiosis
AGP
Practice Problems
100
The types of cells that Meiosis creates at the end of meiosis 2
Gametes/Sperm and Egg cells
100
True or false: Recessive traits ONLY appear if there are two in a genotype
(Example: aa = wavy hair, Aa = straight hair, AA = straight hair)
(If false, write the correct definition)
What is True
100
If each gamete has 23 chromosomes, how many would a zygote have?
What is 46 chromosomes
200
Definition of Homologous chromosomes
What are: Chromosomes that have the same size and genes
200
The amount of alleles a person can inherit per gene
2 alleles per gene (or 2 alleles per trait)
200
For Hair color, Mom has black hair and her genotype is Ff. Dad has Black hair and his genotype is Ff.
What are the possible genotypes and phenotypes their children could have?
F=Black hair
f=Blonde hair
What is: FF: black hair, Ff: Black hair, ff: Blond hair
300
The amount of Chromosomes in the cells before meiosis. What would best describes this?
What is 46 or Diploid before meiosis
300
The difference between genotypes and phenotypes.
Give an example of each
What is: genotypes are the genetic makeup of DNA, Phenotypes are the traits we can see
Example: Genotype AaBBcc
Phenotype: Brown eyes, curly hair, nearsighted
300
Mom's genotype is AaBbCc. What would her gamete be to make her offspring have all recessive traits?
What is: Her gamete would need to have a,b,c
400
The amount of chromosomes in each gamete after meiosis. What word best describes this?
23 chromosomes, or haploid
400
Is it possible for different genotypes to have the same phenotype? Explain. (DO NOT JUST WRITE YES OR NO)
What is: Yes it is possible. For a trait. FF and Ff would appear as whatever F is responsible for.
F is the dominant allele, so that is the phenotype that we will be able to see.
400
If crossover were to happen at 1, then 4, then 6, what would be the genotypes of each homologous chromosome?
Daily Double: Show each gamete
What is:
500
The Definition of Genetic Crossover in Meiosis
NEED TO USE: Homologous chromosomes, Alleles, the phase that crossover takes place in
When homologous chromosomes swap alleles with each other during the Prophase of Meiosis 1.
500
Is it possible for parents that both have a dominant phenotype to have a child with a recessive phenotype?
What is your reasoning for this
What is yes: they could be both Aa and both of the could pass down the a allele making the child aa.
500
How does Genetic crossover in Meiosis explain why siblings look different than each other?
Use vocab: Crossover, Meiosis, Allele, Genotype, Phenotype, Gamete
During meiosis, the parent's chromosomes crossover. Their alleles on their chromosomes swap places. They divide into gametes that are not identical to each other. During fertilization, one of those gametes from the mother will combine with one from the father
Your sibling can be made up of gametes with different chromosomes from each other. This means that their genotypes and phenotypes will be different than yours
