Which of the following is a true statement about a human zygote? correct answers This diploid cell contains all of the genetic information for the individual it will become. Which of the following sets of statements is true of a homologous pair of chromosomes? correct answers They have the same genes but unique alleles. One member of the pair is inherited from each parent. Can the expression of highly heritable traits, such as maze-running ability in rats, be influenced by environment? Why...

How does internal fertilization facilitate life on land? - ANSWERInternal fertilization allows the sperm to reach the egg without either gametes drying out If a hermaphrodite self-fertilizes will the offspring by identical to the parent? Explain? - ANSWERNo. Owing to random assortment of chromosomes during meiosis the offspring may receive the same copy or different copies of a particular parental chromosome from the sperm and the egg. Furthermore, genetic recombination during meiosis will re...

Meiosis 10-4-21 • explain the purpose and location of meiosis - Meiosis occurs in sex organs. Germ cells undergo meiosis. - The purpose is to create gametes or genetically unique haploid cells made for fertilization. It exists to produce GENETIC VARIETY. - Location: in the sex organs. Germ cells go through meiosis to become gametes (sperm or egg). • explain the process of meiosis, noting what occurs in meiosis I versus II, the timing, purpose, and The outcome of crossing over - Mei...
