Genetics and Evolution

Crossing over occurs during

• Metaphase

• Diplotene

• Pachytene

• Anaphase

Crossing over is responsible for

• Dominanace of genes

• Segregation of genes

• Recombination of genes

• Linkage between genes

Linkage prevents

• Segregation of genes

• Homozygous condition

• Heterozygous condition

• All of these

In higher organisms , cytoplasmic inheritance is also called

• Maternal inheritance

• Paternal inheritance

• Plasmon

• All of the above

Cytoplasmic inheritance is due to

• Plastids

• Mitochondria

• Cytoplasmic particles

• All of the above

What this image is showing

• Synapsis

• Crossing over

• Linkage

• Duplication

The image is showing---------aberration in chromosome

• Inversion

• Translocation

• Duplication

• Deletion

Percentage of crossing over is more when

• genes are located in a different cell

• genes are not linked

• linked genes are located close to each other

• linked genes are located far apart from each other

linked genes are located far apart from each other

• Mitochondria

• Chloroplast

• Lysosomes

• Both a and b

Chromosomes found in the salivary gland of Drosophila is

• Polytene

• Lampbrush

• Supernumerary

• Both a and b
