Each gene has 2 types of alleles- one is the dominant allele which always expresses itself that is in both homozygous and heterozygous conditions whereas the other one is the recessive allele which can only express itself in the homozygous conditions.

In Mendel's experiments when he crossed plants with different traits he observed that in the F1 generation there was always a single trait that was getting expressed and it was the trait that was being coded by the dominant allele.

Can you please tell me an explanation of what happens during the metaphase stage of mitosis?

Goshia [24]

Sure! The metaphase stage in the cel is the third step in mitosis. The chromosomes line up in the middle of the cell due to the fact that the spindle fibers pull them towards the middle (the chromosomes are in a single file line). In addition, the spindle fibers connect to the centromeres. Hope this helps :)
