Heredity
What process occurs after DNA replication in meiosis but not typically in mitosis, contributing to genetic variation?
Considering polygenic inheritance of skin pigmentation in humans, what pattern of inheritance might be observed in a family where both parents have intermediate shades, given the continuous variation displayed by the trait?
What structural adaptation allows histones to play their role in chromatin organization?
What outcome would you expect if a small group of fruit flies carrying an allele for red eyes becomes isolated from a larger population with predominantly white-eyed individuals due to geographic barriers?
Which component ensures that each gamete receives only one chromosome set during meiosis?
In a plant species where red flower color (R) is dominant over white (r), what unique phenotypic ratio would you expect in the F2 generation from a dihybrid cross RrYy x RrYy if there's linkage between R and Y genes and no crossing over occurs?
In a dihybrid cross between two heterozygous individuals (AaBb x AaBb), what is the probability of producing an offspring with the genotype Aabb?
