Summary Introduction

To explain:

How the triploid number accounts for Cavendish banana’s inability to form normal gametes as it is a triploid variety. Discuss how the absence of sexual reproductionmight make this species vulnerable to infection

Introduction:

Ploidy refers to the number of sets of chromosome present in a cell. Haploid refers to one set of chromosome (n), while diploid cells contain two set of chromosomes (2n). Generally, haploid cells are germ cells which are the product of reductional division (meiosis), rest of the body cells are diploid.

Mitosis produces 2 daughter cells that are identical to the starting cell. Explain how meíosis is different using this diagram to help you. 1) How many cells are created through meiosis? 2) Describe the chromosomes in each gamete at the end of meiosis? Are the set of chromosomes in a gamete identical to the starting cell like they are in mitosis? Are there the same number of chromosomes in each gamete as the starting cell? Starting cell's chromosomes: 1А, 1B, 2A, 2B Interphase After the S phase of interphase: 4 pairs of sister chromatids 1A 1A 1B 1B 2A 2A 2B 2B Meiosis has 2 rounds of cell division 1A, 1A, 1B, 1B, 2A 2B 2A 2B tv MacBook Air DII DD 80 888 F9 F10 F6 F7 F8 F4 F3 * #3 2$ % & 8 9 3 4 E T.

Unlike mitosis, meiosis in male mammals results in the formation of a) one haploid gamete b) three diploid gametes c) four diploid gametes d) four haploid gametes Please I need a surely answer and a quicker response
please answer, do not copy from google please   What is the shape of the ascus? The ascospores inside the asci are produced by meiosis. Are ascospores haploid or diploid? Interspersed among the asci are sterilefilaments, the paraphyses. Deduce the function of paraphyses. The ascospores are released from the asci and undergo mitotic division upon germination. Are the individuals germinating from ascospores haploid or diploid?
