You are traveling again as the science officer and discover a new species on planet Barkley. You are able to obtain some cells from the organism and know that it reproduces sexually. You make a chromosome spread and from what you know about human cells, identify the various regions indicated by the arrows, create a karyotype and predict the number of chromosomes.

Use the following information as the basis for answering the question: A diploid eukaryotic organism has 4 unique chromosomes. Chromosome I is metacentric, chromosome II is telocentric, chromosome III is submetacentric, and chromosome IV is acrocentric. Draw a detailed picture of a germ cell from this organism in Metaphase of Mitosis and label all chromosomal and cellular components. Be sure to label each chromosome (I, II, III, or IV) and include the following in your drawing: centrosomes, 3 kinds of microtubules, metaphase/equatorial plate, and plasma membrane. Use the letter p to indicate a paternal chromosome and m to indicate a maternal chromosome.

Assume that cell does mitosis Assume that cell does meiosis What is the diploid number of chromosomes in this organism? Give the number of chromosomes and the number of DNA molecules per cell present at the stages represented. I tried to solve them, but I'm not sure what I did right and what was wrong. Please correct it for me. See that attached photo.
Somatic cells in organisms of a particular diploidplant species normally have 14 chromosomes. Thechromosomes in the gametes are numbered from 1through 7. Rarely, zygotes are formed that containmore or fewer than 14 chromosomes. For each of thezygotes below, (i) state whether the chromosomecomplement is euploid or aneuploid; (ii) provideterms that describe the individual’s genetic makeupas accurately as possible; and (iii) state whether ornot the individual will likely develop through theembryonic stages to make an adult plant, and if so,whether or not this plant will be fertile.a. 11 22 33 44 5 66 77b. 111 22 33 44 555 66 77c. 111 222 333 444 555 666 777d. 1111 2222 3333 4444 5555 6666 7777
Mitosis is used to make more body cells while meiosis is only used to make gametes for sexual reproduction. Use the diagram to identify one similarity and one difference between mitosis and meiosis.
