define one genetic map unit ~ the physical distance between two genes that results in a 1% frequency of recombination In birds, sex is determined by ZW chromosome inheritance. Males are ZZ and females are ZW. Within pigeon populations there is a recessive, Z-linked allele that is lethal in embryos. What is the expected sex ratio in the offspring of a cross between a male that is heterozygous for the lethal allele and a wildtype female? ~ 2:1 male to female A recessive allele on the X c...

USABO – Genetics Prediction Questions 2024. homologous chromosomes - ANSWER Chromosomes that have the same sequence of genes and the same structure chiasmata - ANSWER X-shaped regions where crossing over occurred. cohesins - ANSWER Proteins that hold sister chromatids together crossing over - ANSWER Process in which homologous chromosomes exchange portions of their chromatids during meiosis. synaptonemal complex - ANSWER A zipper-like protein structure that causes replicated h...

A carrier is an individual who has an allele associated with a trait but does not display the trait. They are, however, able to pass on the allele to their offspring. When setting the simulation's conditions as described above, why does it make no difference whether or not you turn on "show carriers"? Settings: Mode of inheritance - Dominant Parental generation - Male - Heterozygous Female - Heterozygous Matings between relatives - disallow Progeny in first generation - 4 Show carri...

What is inheritance? the process by which characteristics are passed from one generation to another Who was Gregor Mendel? The father of genetics; studied relationships between traits expressed in parents and offspring and hereditary factors causing the expression of these traits. What is the generation of plants used to perform the first cross called? P1 generation F1 generation first generation of offspring resulting from two P1 crosses F2 generation generation resulting from cross...

Sister chromatids are which of the following? a. Found right after a cell divides. b. Formed when chromatids separate during cell division. c. Unique to prokaryotes. d. Tightly linked together at a centromere. e. Made only of DNA - Answer-d. Tightly linked together at a centromere. Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you re...

Bio 181 Chapter 14"blending" hypothesis - correct answer The idea that genetic material from the two parents blends together (like blue and yellow paint blend to make green) "particulate" hypothesis - correct answer the idea that parents pass on discrete heritable units (genes) character - correct answer A heritable feature that varies among individuals (such as flower color) trait - correct answer Each variant for a character, such as purple or white color for flowers true-bre...
