It will be the options I and IV because then four gametes will be like upper strand gene A and h and upper strand b will form Ahb.
The lower strand a and H and upper strand b will form aHb.
Upper strand A and lower strand H AND B will form AHB
THE LOWER STRAND a H and B.

Homologous recombination in meiosis has the main purpose of_____ a) DNA repair b) Creating new chromosomes c) Sealing double-stranded breaks 4. Strand invasion usually happens without enzymatic assistance. T/F? 5. When replication fork runs into a nick, it results in a_______ a) single-stranded break b) double-stranded break 6. The invading end is usually a _______ a) 3'...
6.) During meiosis, when crossing-over occurs between two homologous chromosomes, it does not happen at a single point, but rather two points with a stretch of DNA in between. a. What are the two junction points called? b. What is the region between the two points called and what is different about this region compared to how double-stranded DNA usually is? c. If the region described in b.) is located within a gene and the two homologues have different alleles...
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...
alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
Consider two non-homologous chromosomes whose normal sequence of segments and centromere locations are shown here. What kind of changes are these? I think it's a translocation and i cannot tell what the second one is. Question 7: (2 points) Consider two non-homologous chromosomes whose normal sequences of segments and centromere locations are shown here. Chromosome 1 A B C D E F G H Chromosome 2 O R . S T U V Determine the type (or types) of chromosomal...
Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...
28. Which of the following happens at the conclusion of mmeiosis 1 a. Homologous chromosomes are separated. b. The chromosome number is conserved e. Sister chromatids are separated. d. Four daughter cells are foemed. e· The sperm cells elongate to form a head and a tal end. 29. Crossing over occurs during which phase of meiosis? d prophase II e. metaphase Use the following key to answer the following questions. Each answer mey be not at al. wsed once, mone...
1. A genetic cross in which the inheritance of two traits is observed is called a A) Dihybrid cross. B) Monohybrid cross C) Backeross D) Testcross 2. For single crossovers, the frequency of recombinant gametes is half the frequency of crossing over because A) A testeross between a homozygous and heterozygote produces 1/2 heterozygous and 1/2 homozygous progeny. B) The frequency of recombination is always 50%. C) Each crossover takes place between only two of the four chromatids of a...
