Why is a variegated plant considered heteroplasmic? O The plant has mutant and wild-type chloroplast DNAS distributed amongst the cells in different ratios. The plant has only two types of cells, one with only mutant chloroplast DNAS and one with only wild-type chloroplast DNAS. O All of the plant's cells have mutant and wild-type chloroplast DNAS. All of the plant's cells have mitochondria and chloroplasts.

Need help on this question
Need a explanation of genetic question
Assume that diploid plant A has a cytoplasm genetically different from that of plant B. To study nuclear–cytoplasmic relations, you wish to obtain a plant with thecytoplasm of plant A and the nuclear genome predominantly of plant B. How would you go about producingsuch a plant?

A plant heterozygous for stem height and homozygous dominant for flower color is crossed with another plant recessive for both traits. What will the ratio of offspring be in the F1 generation? What genotypes in a parental generation will produce a 9:3:3:1 phenotypic ratio in offspring? Show your work. 5. A pure breeding, spherical yellow plant is crossed with a pure-breeding dented green plant. What will be the genotypic and phenotypic ratios in the F1 and F2 generations? 6.

Mitosis must be carefully regulated to ensure the normal distribution of chromosomes to the daughter cells. A ring-shaped protein molecule known as cohesin attaches to the centromere of a chromosome and holds sister chromatids together to prevent their premature separation. Enzymes detach cohesin molecules from the centromere immediately before the sister chromatids segregate. -based on Nature, 2006 In which of the cells labelled in the diagram above are enzymes most likely acting to detach cohesin molecules from the centromere?

puey drganlsm yo are working with has the following chromosomes. Place the chromosomes of this organism onto the cell below such that the diagram accurately shows a cell from this organism in metaphase of mitosis. Note 1: Only place chromosomes you need. You don't need them all. Note 2: You can place the 'Blank Box' image if you don't think you need a chromosome at a particular position. Dashed line - the metaphase plate 1.
