Exam 13: Meiosis and Sexual Life Cycles

You have isolated DNA from cells in different stages of meiosis within one species.You have determined the relative DNA content for each type,and plotted the results on the graph shown below.Refer to the graph to answer the following questions. -If the species were known to be haploid,which sample might represent a zygote?

A certain gene found in a diploid species is known to have 18 alleles (variants).Any given organism of that species can/must have which of the following?

The karyotype of one species of primate has 48 chromosomes.In a particular female,cell division goes awry and she produces one of her eggs with an extra chromosome (25).The most probable source of this error would be a mistake in which of the following?

Refer to the drawings below of a single pair of homologous chromosomes as they might appear during various stages of either mitosis or meiosis,and answer the following questions. -Which diagram(s)represent anaphase II of meiosis?

How do cells at the completion of meiosis compare with cells that have replicated their DNA and are just about to begin meiosis?

When an individual chromosome carries DNA from two different parents,it is said to be

You have isolated DNA from cells in different stages of meiosis within one species.You have determined the relative DNA content for each type,and plotted the results on the graph shown below.Refer to the graph to answer the following questions. -Which sample might represent an animal cell which is at the end of meiosis II?

Refer to the information and figure below to answer the following question(s). A certain (hypothetical)organism is diploid,has either blue or orange wings as the consequence of one of its genes on chromosome 12,and has either long or short antennae as the result of a second gene on chromosome 19,as shown in the figure. -A certain female's number 12 chromosomes both have the blue gene,and number 19 chromosomes both have the long gene.As cells in her ovaries undergo meiosis,her resulting eggs (ova)may have which of the following?

Independent assortment of chromosomes is a result of

Refer to the information and figure below to answer the following question(s). A certain (hypothetical)organism is diploid,has either blue or orange wings as the consequence of one of its genes on chromosome 12,and has either long or short antennae as the result of a second gene on chromosome 19,as shown in the figure. -A female with a paternal set of one orange and one long gene chromosome and a maternal set comprised of one blue and one short gene chromosome is expected to produce which of the following types of eggs after meiosis?
