Explain how meiosis and fertilization lead to varied offspring. What is the difference between meiosis I and II? Explain the nondisjunction that occurs in males/females during meiosis I and II. Explain the process of mitosis and meiosis. Explain in detail how they differ. ...
Explain the process of mitosis and meiosis. Explain in detail how they differ. Suppose all seed plants were homosporous, what effect would that have on their reproduction? Stimulation of the EGF growth receptor pathway results in the production of Cycl...
(a)(mitosis) chromosome numbermaintained 1 diploid AW +(meiosis) chromosome numberhalved / haploid AW;(mitosis) identical offspring /clones + (meiosis) to producenon-identical gametes / sexcells / any gamete correctlynamed;(mitosis) e.g. of where it occurs- plant or animal / in bacteria;gro...
Mitosis/MeiosisThe genetics parts of the mitosis/meiosis just confuses me.Here are a few terms I'm getting mixed up,please define (to the best of your capability,please be concise and simple,don't give me dictionary meanings) and explain them.1.chrom
In the first meiotic division (MI) of oocytes, the cortically positioned spindle causes bivalent segregation in which only the centre-facing homologue pairs are retained. ‘Selfish’ chromosomes are known to exist, which bias their spindle orientation and hence retention in the egg, a process known...
Sexual dimorphism in dioecious plants refers to sexual differences in primary and secondary sex characteristics1,2. Such divergences between males and females are the results of sexual selection for traits that influence individual fitness during the evolution process3. Selective pressure may lead to se...
Understand the context: Zinder and Lederberg were studying genetic exchange in bacteria, specifically looking at how genetic material could be transferred between bacterial cells. Identify the key observation: They observed the formation of prototrophs, which are bacteria ...
If it occurs in meiosis II, there will be 2 normal gametes and 2 abnormal. Answer and Explanation: (a) Trisomy 21 is having three copies of chromosome 21. This could have resulted from the nondisjunction of the 21st chromosome...
1. Refer to the diagram in Model 1. a. What are the three parts of a nucleotide? The three parts are Phosphate, Deoxyribose sugar, and Nitrogen-containing base. b. What kind of sugar is found in a nucleotide? Sugar that is found in Nucleotide is Deoxyribose sugar. ...
Describe the process of crossing over and its importance in genetic recombination. Describe the process of mitosis and meiosis. Explain each in detail. Define genetic recombination. In what two ways does this occur during meiosis? Explain both meiosis and mitosi...
