- Which one of the following entries describes the relationship between sister chromatids? Contain the same genes, but may be different alleles Contain identical alleles of the same genes Inherit one homologous chromosome from mother, inherit one homologous chromosome from father. Very similar at the DNA sequence levelarrow_forwardUse 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.arrow_forward#10: knowledge in geneticsarrow_forward
- The following four questions refer to the picture below: 1) In meiosis, the homologous chromosomes are side by side. Are they side by side in mitosis? 2)In meiosis, each centromere has a spindle fiber attached only to one side. In mitosis, each centromere has a spindle attached to how many sides? 3) Look at what happened right after Metaphase in both processes. In mitosis, what has been separated homologous chromosomes or sister chromatids? 4) After Metaphase I in meiosis, what has been separated, homologous chromosomes or sister chromatids?arrow_forward#5: knowledge in geneticsarrow_forwardTruffles (Tuber borchi) have 2n=8 chromosomes. For the mitotic and meiotic stages below, draw the chromosomes and chromatids, and give the number of homologous pairs, chromosomes, and chromatids present. Be sure to differentiate homologous chromosomes by using size, shape, or other labeling mechanism. Metaphase of mitosis ( # homologous pairs # chromosomes # chromatids Anaphase of meiosis II – draw and count chromosomes for only 1 cell ( # homologous pairs # chromosomes # chromatidsarrow_forward
- Order the molecules/structures listed below from least condensed to most condensed. Naked DNA Chromosome Chromatin Source Targetarrow_forwardWhich of the following chromosome pairs would contain all of the same genes (not necessarily at the same loci)? OA homologous pair of chromosomes after a deletion in one chromosome in the pair A homologous pair of chromosomes after an inversion in one chromosome in the pair A pair of sex chromosomes in a male human A homologous pair of chromosomes after translocation occurs in one chromosome in the pairarrow_forwardExplain the terms haploid, diploid, and polyploid. Why is polyploidy so much more common in plants than in animals? Give examples of polyploid animals. Polyploid plants may occur naturally or they may be created intentionally by agricultural scientists. List four examples of polyploid commercial crops and explain why they are superior to their diploid ancestors.arrow_forward
- Discuss the concepts of homologous chromosomes, diploidy, and haploidy. What characteristics do two homologous chromosomes share?arrow_forwardconsider the metaphase (mitosis) chromosome spread of the following related animal species. The first meiotic division in the hybrid animal shows a mixture of paired and single chromosomes. Why do you suppose this occurs? Can you suggest a possible relationship between the mixed chromosomes and the observed sterility of the hybrid?arrow_forwardConsider a hypothetical DIPLOID organism with ONE PAIR of homologous chromosomes. How many DNA molecules are there per nucleus in a somatic cell in G1? 4 8 2 1 Picture 1 shows Bob’s chromosome #18 pair. Picture 2 shows Sue’s chromosome #18 pair. Bob and Sue have a stillborn son with three copies of chromosome #18 that look like picture 3. In which parent did the chromosome separation problem occur? Bob Sue Both parents You need additional information to determine which parent. Starting with a population of genetically identical mice, you discover two new independent mutant strains in which all of the animals have epileptic seizures. In both strains, you know that the epileptic seizures are due to a single DNA mutation. You cross a mutant mouse from one strain to a mutant mouse from the second strain and find that none of their many offspring undergo spontaneous seizures. From…arrow_forward
