18 Questions
Which process reduces the chromosome number from diploid to haploid?
Meiosis
What would happen if gametes were produced by mitosis instead of meiosis?
Offspring would have double the number of chromosomes as the parents
Which cells have a haploid set of 23 different chromosomes?
Gametes
What is the main difference between mitosis and meiosis?
Mitosis has one cell division, meiosis has two
What is the function of meiosis in gamete formation?
To reduce chromosome number by half
What is the significance of homologous chromosome pairs in inheritance?
To control different inherited characters
What is the primary difference between mitosis and meiosis?
Mitosis produces two identical daughter cells, while meiosis produces four genetically distinct daughter cells.
Which of the following events is unique to the first division of meiosis (meiosis I)?
Pairing of homologous chromosomes to form tetrads.
What is the purpose of crossing over during meiosis I?
To increase genetic diversity in the resulting gametes.
Which of the following statements about the second meiotic division (meiosis II) is true?
The processes during meiosis II are identical to those of mitosis.
What is the significance of the tetrad formation during meiosis I?
It allows for the exchange of genetic material through crossing over.
Which of the following statements about the alignment of chromosomes during meiosis I is correct?
Homologous pairs of chromosomes are aligned at the metaphase plate.
What process leads to the separation of alleles during gamete formation?
Meiosis
Which term describes an organism with two different alleles for a gene?
Heterozygous
In the F2 generation, what is the expected phenotypic ratio of purple to white flowers?
3:1
Which genetic vocabulary term describes an organism's physical appearance?
Phenotype
What type of gametes can be produced by a Pp plant?
Both P and p gametes
How do homozygotes differ from heterozygotes in terms of true breeding?
Homozygotes are truebreeding, but heterozygotes are not.
