Somatic cells are: A. Haploid B. Diploid C. Egg and sperm D. Important in meiosis. Which of the following is/are true concerning spermatogenesis? a. Occurs in the gonads of the male where FSH targets spermatogonia b. Spermatogonia have 46 chromosomes and go through mitosis before meiosis c...
Does meiosis occur in all cells at least once? (a) Are cells haploid or diploid during telophase? (b) Does this occur in meiosis? One replication of chromosomes followed by two subsequent divisions occurs: a. in meiosis. b. in mitosis c. in both meiosis and mitosis. d. in cytokinesis....
Meiosis only occursin reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and...
What begins with a haploid cell? Where are somatic cells produced? Where does meiosis take place in bryophytes? What does human fertilization start with? What is a haploid gamete? Where does the yolk sac go in embryonic development? Where does sperm production occur within the testis? How is...
Aneuploidy is caused by nondisjunction, whichoccurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The loss of a single chromosome from a diploid genome is called monosomy (2n-1), while the gain of one chromosome is called trisomy (2n+1). ...
Crossing over occurs during prophase I of meiosis. During this process, homologous chromosomes line up next to each other and swap homologous sections of their DNA.Answer and Explanation: Crossing over occurs in order to increase genetic diversity of the offspring. Genetic diversity is the amount ...
Are diploid cells formed when a sperm fertilizes an egg? How does the zygote form the organism? When does meiosis 2 occur? How many days can sperm live in the fallopian tube? How does the formation of the ovum occur and how it is different from the formation of sperm cells?
Two successive nuclear divisionsoccur, Meiosis I (Reduction) and Meiosis II (Division). Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. What occurs after mitosis? Once mitosis is complete, the entire cell divides in two by way of the process calledcytokinesis(Figure 1). ...
from Chapter 8 / Lesson 16 27K This lesson will discuss diploid cells and what makes a cell diploid. It will also cover what the difference between haploid and diploid cells is, along with why diploid cells are important. Related to this QuestionWhat...
In a sexual life cycle involving the alternation between haploid and diploid phases: a. meiosis gives rise to the haploid phase. b. the product of fertilization is a diploid zygote. c. the gametes are haploid. d. all of the above. e. b and c, but not a ...
