A human has 23 pairs of chromosomes. Ignoring the effects of crossing over, what is the likelihood that a woman could produce an egg cell having only maternal homologues (only "blue" chromosomes, no "red" chromosomes).
A cell undergoing meiosis has four pairs of homologous chromosomes. How many different combinations of maternal and paternal chromosomes are possible within the daughter cells that form? (Do not consider crossing over in your answer.) a.16 b. 8 c. 4 d. 2
A diploid cell contains three pairs of homologous chromosomes designated C1 and C2, Ml and M2, and S1 and S2. No crossing over occurs. What combinations of chromosomes are possible in: daughter cells following mitosis?
Consider a diploid cell where 2n = 6. During metaphase I of meiosis, as the pairs of homologous chromosomes line up on the metaphase plate, each pair may orient with its maternal or paternal homolog closer to a given pole. There are four equally probable arrangements of the homologous pairs at metaphase I. (Note that this problem assumes that no crossing over has occurred.)The cells below show the eight possible combinations of chromosomes that the daughter cells of meiosis II...
Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...
Has the homologous pair of chromosomes pictured to the right undergone crossing over? Explain your answer either way.
underers meiosis, how many cells will result, 12) If a eukaryotic cell has 20 chromosomes and and how many chromosomes will they contain? A) 4 cells, each with 20 chromosomes B) 4 cells, each with 10 chromosomes C) 2 cells, each with 10 chromosomes D) 2 cells, each with 20 chromosomes Answer: 13) Crossing over occurs during which stage of meiosis? A) telophase I B) metaphase II C) anaphase II D) prophase II E) prophase I Answer: 14) Which of...
Consider a diploid cell that contains 6 pairs of chromosomes. Each pair includes a maternal and a paternal member (for example: Am Ap(one pair) or Am Ap Bm Bp (two pairs). How many different combinations of chromatids are possible during the early phases of anaphase in meiosis II? Enter you answer as a whole number: ______[a]__________.
If a diploid organism has 8 pairs of homologous chromosomes and one of the 8 pairs is the pair of sex chromosomes. How many total chromosomes does the organism have? How many total autosomes does the organism have? How many chromosomes do gametes of this organism have?
1) An organism has 2n = 6 chromosomes with alleles A B / a b on the chromosome 1 homologous pair, alleles D / d on the chromosome 2 homologous pair, alleles E F / e f on the chromosome 3 homologous pair. Show two different ways that chromosomes could align at the metaphase plate during Meiosis I (show the chromosomes and alleles). Assume no crossing over. How many combinations of chromosomes are possible in the gametes? Please show me...
