Chromosomes
What does it mean if a cell is haploid?
What is the process of creating gametes called?
Meiosis
Dominant
What does it mean if a gene is homozygous?
The alleles for that gene are the same
What are the phases of Mitosis?
Prophase, Metaphase, Anaphase, and Telophase
What does it mean if a cell is diploid?
The cell has 2 copies of each chromosome
What is the purpose of Meiosis?
Creating gametes
What is the allele for a trait that might not always be present called?
What does it mean if a gene is heterozygous?
The alleles for that gene are different.
Does Mitosis benefit sexual reproduction or asexual reproduction?
Asexual
If a human cell has 23 chromosomes, is it haploid or diploid?
Haploid
4
If an offspring's genotype is Ss, will the dominant or recessive trait be expressed?
Dominant
If an offspring's genotype is GG, is that homozygous or heterozygous?
Homozygous
What is crossing over?
Chromosomes exchanging genes before Meiosis
If a human cell has 46 chromosomes, is it haploid or diploid?
Diploid
Prophase I, Metaphase I, Anaphase I, Telophase I
You cross parents Pp x Pp, what are the probabilities the child will express the dominant phenotype?
75%
If an offspring's genotype is heterozygous dominant, what would the genotype be: AA, Aa, or aa?
Aa
Do chromosomes get split up during Meiosis?
Yes
If a fly's diploid number is 78, what is its haploid number?
39
Sexual
You cross parents Pp x pp, what are the probabilities the child will express the dominant phenotype?
50%
If you cross a parent with genotype AA with a parent with genotype Aa, what are the odds that the offspring will be heterozygous dominant?
50%
