Yes the chromosome pair has undergone crossing over. Because one of the chromosome is red in colour and the other chromosome is blue in colour. The chromosome which is red in colour shows a small fragment of blue colour and the chromosome which is blue in colour shows a small fragment of red colour. It means both the chromosomes have undergone crossing over and have exchange their genetic material.

QUESTION 3 Crossing over refers to the pairing of homologous chromosomes during melosis a mutation that makes all alleles in homologous chromosomes identical an exchange of segments between the two members of a homologous chromosome pair during meiosis the loss of one or more chromosomes during melosis QUESTION 4 Place the following events of Meiosis I and Meiosis ll in the correct order: Duplicated chromosomes are separated Duplication of chromosomes Crossing over occurs Homologous chromosomes pair up - Homologous chromosomes...
Draw a pair of homologous chromosomes and assign 7 genes along their length. Using your chromosomes above draw an intercalary deletion Draw your homologous chromosomes undergoing unequal crossing over. What mutations occur as a result of unequal crossing over?
Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...
Without crossing over, the independent assortment of the homologous chromosomes in a cell with these chromosomes will produce two different genotypes. Which are they? without produce we gw the dependentm ent of the homologous commence with these chromosomes n t types which are they XX ORT, Rein
A house fly has 12 homologous pairs of chromosomes. ignoring the effects of crossing over, how many possible combinations of maternal and paternal chromosomes would be found in a fly's egg? show your calculations.
1. Crossing over is important because it _____. a. allows the exchange of genes between homologous chromosomes b. prevents variation in gametes c. holds tetrads together d. ensures that homologous chromosomes pair up 2. The M phase of mitosis and M phase of meiosis both occur after interphase. However, the two processes differ in the arrangement and behavior of their chromosomes. How? a. Homologous chromosomes pair up in mitosis, but not in meiosis. b. The pairing up of homologous chromosomes...
Chromosomes can exchange genetic information during a process called “crossing over.” This occurs when homologous chromosomes are lined up in pairs. When does this happen? View Available Hint(s) Chromosomes can exchange genetic information during a process called “crossing over.” This occurs when homologous chromosomes are lined up in pairs. When does this happen? a, anaphase II b, prophase I c, anaphase I d, metaphase II
Question 2: The Atlas blue butterfly has 224 homologous pairs of chromosomes. Each pair consists of one chromosome from the butterfly's mother and one from its father. A. Assuming no crossing over, what is the probability that a sperm this butterfly makes has all of the chromosomes from the butterfly's own father? Why? (You do not need to calculate out this number- a number with an exponent is fine.) (roughly 3-4 sentences) B. How many chromosome 17's does this butterfly...
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...
Crossing over refers to the exchange of genetic material between two homologous chromosomes. Which of the following statements about this event is correct? a. Crossing over is more likely to occur between two genes that are widely separated on the chromosomes. b. Crossing over is more likely to occur with recessive alleles than with dominant ones. c. Crossing over is more likely to occur between two genes that occur next to each other on a chromosome. d. Both the first...
