Does crossing-over between two sister chromatids during prophase of meiosis I contribute to genetic variation? Explain your answer.
Homework Answers
Crossing over between two sister chromatids during prophase of meiosis 1 to contribute genetic variation. Crossing over is the exchange of genetic material or genes between homologous chromosomes.
In sexual reproduction gamete of male and female are fused and reproduce an offspring.These two different gametes when fused it's the first source of genetic variation in prophase of meiosis 1st. In offspring Each gamete contains a different set of DNA.This produce a very unique combination of the genes in offspring.The combination of different genes on a chromosomes is lead to new traits in offspring.In human 99% of human is equal but differences are showed when different genes combined.
Homologous chromosomes forms pairs during prophase 1 of meiosis 1 and crossing over is occur.Result of Crossing over in new combinations of genes that present on each chromosome.

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...

Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...

Unequal crossing over during prophase I can result in one sister chromosome with a deletion and another with a duplication. A mutated form of hemoglobin, so-called hemoglobin Lepore, exists in the human population. Hemoglobin Lepore has a deleted series of amino acids. If this mutated form was caused by unequal crossing over, and removed TAGGATA, what does a normal and a Lepore gene look like? Draw a diagram illustrating a normal and a diagram of a Lepore gene.

During meiosis I: A. chromosomes undergo equational division B. sister chromatids are separated C. recombination occurs during anaphase I D. bivalents are formed during prophase I and are taken apart during anaphase I
