- Each sperm of a tomato plant contains seven chromosomes. What are the haploid and diploid number for tomatoes? haploid=7 and diploid=14 haploid=14 and diploid=7 haploid=7 and diploid=49 haploid=3 and diploid=7Discuss the following sets of terms: a. trisomy and triploidy b. aneuploidy and polyploidyWhich of the following statements is not true in comparing mitosis and meiosis? a. Twice the number of cells are produced in meiosis as in mitosis. b. Meiosis is involved in the production of gametes, unlike mitosis. c. Crossing over occurs in meiosis I but not in meiosis II or mitosis. d. Meiosis and mitosis both produce cells that are genetically identical. e. In both mitosis and meiosis, the parental cell is diploid.
- Chewbacca from Starwars is a part of a species that has 64 chromosomes for its diploid number. What would it haploid number be?In tomatoes, red fruit is dominant to yellow fruit, and purple stems are dominant to green stems. Thegenes encoding these traits are on different homologous chromosomes. The progeny from a matingconsisted of 305 red fruit, purple stem plants; 328 red fruit, green stem plants; 110 yellow fruit,purple stem plants; and 97 yellow fruit, green stem plants. What would be the genotypic and phenotypic outcome if each parent was self-fertilized?. With regards to the grasshopper testes experiment, diakinesis is an ideal stage to determine chromosome number due to the degree of condensation of the chromosomes? Count the chromosomes at this stage. Does it represent a diploid or a haploid number?
- An equational division of mitosis is occuring for a diploid organism that has three heterologous chromosomes. One acrocentric, one metacentric and one telocentric.
