Concept explainers

Violence

Violence is defined as a physical act that causes or is intended to cause harm. Violence can cause physical, emotional, or both types of harm. Violence is defined by the World Health Organization as the intended use of physical force and power that causes threat or harm against oneself, another person, or against a community or group, and has the potential to cause damage, death, mental distress, maldevelopment, or poverty.

Question

I need help with this biology homework question.

includes two phases
Using what you know about chromosomal crossover, explain why two
siblings who share both parents might look different.
Your answer
How does metaphase in meiosis I differ from metaphase in mitosis?

Expert Solution

Step 1Part 1

Chromosomal crossover : It is defined as the exchange of genetic material between two homologous chromosomes which are non sister chromatids and they result in recombinant chromosome.

So because of recombination siblings share approximately 50% of the same DNA as each parent passes only 50 % of the genes randomly to the child . So each child may get different genes from their parents so they recombine differntly and they look different.

Place the events of meiotic crossover in order of their occurrence, from the start of prophase I to the start of metaphase I. Prophase I Metaphase I Answer Bank Chromosomes begin to condense. Chromosomes condense further as chiasmata become more visible during separation. The synaptonemal complex aligns homologs into tetrads. Crossing over occurs, during which non-sister chromatids exchange DNA. Homologs are connected by chiasmata as the synaptonemal complex begins to separate.
