During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.
Explanation:
Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.
In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.
Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.

Biennial plants</h2>
Explanation:
This plant is a biennial, which means it will just take longer than a season to mature enough to produce flowers.
Since the Sweet William  plant did not flower last year when it was planted and this year also it did not bud till the spring. So, we can assume that these plant will need atleast two seasons to mature hence they are biennials. 
Depending on the life span, plants are classified as annuals (one season), biennials(two season) and perennials (more than two years).
 
        
        
        
Autosomal traits would show Mendelian inheritance pattern but sex-linked traits would show criss cross inheritance.
Sex-linked trait is often controlled by gene present only on X chromosome, hence no corresponding allele is present on Y chromosome.
