When two alleles share dominance
What is codominance?
Define diploid. The diploid # for humans.
What is having a full set of chromosomes (half maternal and half paternal)? What is 46?
Define haploid. What is haploid # for humans?
What is having half the number of chromosomes? What is 23?
Types of cells produced by mitosis and meiosis
What are somatic cells (mitosis) and gametes (meiosis)?
Scientist that discovered gene linkage
Who is Thomas Hunt Morgan?
When both alleles are equally represented in phenotype?
What is incomplete dominance?
What are homologous chromosome?
What is homologous chromosomes carry the same genes (1 maternal and 1 paternal)?
Does not occur during Interphase II (if there is one).
What is copying of DNA?
Following mitosis, the daughter cells would each have a total of ______ chromosomes. After meiosis I, the two daughter cells would have _____chromosomes, and after meiosis II ______ chromosomes.
What is 46, 23, 23?
You cross a white flower and a pink flower and the heterozygous offspring are pink. What type of inheritance does this display?
What is incomplete dominance?
Define crossing over. When does it occur?
When two homologous chromosomes for a tetrad and overlap, exchanging genes (portions of chromatids). Prophase I
Difference between metaphase I and II
What is Metaphase I homologous pairs line up but Metaphase II single chromosomes line up (no pairing)?
Types of cell each begins with
What is a diploid somatic cell?
What TWO types of inheritance does blood typing display?
What are multiple alleles and codominance? 3 alleles and A & B for type B equally expressed in phenotype.
Describe metaphase I.
What is when homologous chromosomes line up (with their partner or as a tetrad) along the middle of the cell and spindles attach to each chromosomes centromeres?
Compare anaphase I with anaphase II
What is anaphase 1 whole chromosome of the tetrad are pulled to opposite sides while A2 splits centromeres and individual chromosomes (once chromatids) migrate to the sides?
Compare resulting cells of mitosis with meiosis (#, cell type, chromosome #)
What is for mitosis 2, somatic, diploid/46 and meiosis 4, gametes, haploid/23?
A person with type O blood is married to a person with type A blood (unknown genotype). They have 6 children, 3 of them have type A blood, three of them have type O blood. What is the genotype of the two parents?
What is the type A person must be heteroyzous to have children who are both A and O. Parents are ii x Ai.
Resulting cells at the end of Meiosis 1 (how many, chromosome #, genetics)
What are 2 haploid genetically unique cells?
Why are cells at end of Meiosis I haploid but still haploid at end of Meiosis II? Explain. (Or why is there even a Meiosis II?)
What is at end of meiosis I they still have sister chromatids attached and therefore count as 1 chromosome but since still contain extra set of DNA, can split again without changing chromosome number but able to produce more cells?
The resulting cells produced via mitosis are similar in both genders, however, meiosis produces different outcome depending on the gender. Describe these gender differences in meiotic cell production.
What is males produced 4 equally sized sperm and females 1 large egg and 3 small polar bodies?
