Carol of the Cells
How many helices are in DNA?
What is a genotype and what is a phenotype?
Genotype = What the chromosomes say
Phenotype = The characteristics of the individual
What is a wild type allele?
What process changes the cis-trans configuration of alleles on different genes?
Recombination
What does a filled in circle mean in a pedigree?
Affected female
Ploidy of a haploid cell?
n or 1n
How many homologs are in a diploid cell?
2
What is a hypermorphic allele?
New alleles with a different cos-trans configuration as compared to the original are called what?
Non-parental
How would you format individual 3 in generation 2
2.3
What are the two main phases of the cell cycle?
Interphase and mitosis
If we cross Dd x Dd, what are the odds that their offspring will have at least one D allele?
3/4
What is the serum antibody for type A blood?
Anti-B
What is a linkage group?
Genes on the same chromosome
What symbols on a pedigree would be affected by a y-linked mutation?
Squares (males)
What are the steps are included in interphase of the cell cycle?
G0, G1, S phase, G2
If we cross Tt x Tt, and the T allele is dominate to the t allele, what are the odds that their offspring with a dominate phenotype will be a heterozygote?
2/3
What is the equation for Chi-squared?
χ² = Σ((O - E)² / E)
They are more tightly linked
What type of mutation is Huntington's disease?
Autosomal dominant
What stage of mitosis happens when the chromosomes are clearly double structures and the centrioles are on the opposite poles. Spindle fibers also form here.
Prometaphase
What type of frequency is mutually exclusive?
Gamete frequency
galactose
What is the formula for frequency of recombination?
r= The Frequency of Recombination= Sum of Non-Parental Progeny / Total Progeny of Test Cross
What type of mutation is hemophilia?
X-linked
