Step by step
Solved in 2 steps
- If a human gamete with a missing chromosome participates in fertilization with a gamete with a normal number of chromosomes, how many chromosomes will the zygote have? Will the zygote be viable? Explain your answer. (Remember, zygotes are diploid)How many homologous pairs of chromosomes would be in the zygote if it were a male organism? Explain.In a possible future scenario, male fertility drops to zero, but, luckily, scientists develop a way for women to pro-duce babies by virgin birth. Meiocytes are converted di-rectly (without undergoing meiosis) into zygotes, which implant in the usual way. What would be the short- andlong-term effects in such a society?
- Define gamete and zygote. What number of chromosomes does each have (in humans)?Why is it necessary for gametogenesis to reduce the chromosome number of the sex cells by one-half?One of the advantages of sexual reproduction is that it promotes genetic diversity in the offspring. This is because gametes are produced by meiosis, which introduces genetic variation into the resulting gametes. How does meiosis accomplish this? Describe one way (there are several choices) in which meiosis produces new combinations of genes in gametes.
- If a human gamete with an extra chromosome participates in fertilization with a gamete with a normal number of chromosomes, how many chromosomes will the zygote have? Explain your answer. (Remember, zygotes are diploid)which of these could lead to the mistake evident in the karyotype? A) a failure of cytokinesis after meiosis I in gamete formation B) a nondisjunction in meiosis II in gamete formation C) crossing over in meiosis ! in gamete formation D) fertilizaton by two sperm in zygote formationHow does the role of meiosis in gamete production differ between organisms with a diploid-dominant life cycle and organisms with an alternation of generations life cycle?
