Which situation is a result of crossing-over during melosis?

During prophase I of meiosis, homologous chromosomes align in a process called synapsis to form a tetrad. In this formation, parts of non-sister chromatids can touch to form a chiasma. Here, parts of homologous chromosomes can be exchanged

Explanation:

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
