Sometimes it can be very difficult and sometimes it can be very easy.
Answer:
Answer is C
Explanation:
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes leading to a variety of cells
Prophase I
The chromosomes condense, and the nuclear envelope breaks down & crossing-over occurs.
Metaphase I
Pairs of homologous chromosomes move to the equator of the cell.
Anaphase I
Homologous chrmosomes move to the oppisite poles of the cell.
Telophase I and Cytokinesis
Chromosomes gather at the poles of the cells & the cytoplasm divides.
Prophase II
A new spidle forms around the chromosomes.
Metaphase II
Chromosomes line up at the equator.
Anaphase II
Centromeres divides & chromatids move to the opposite poles of the cells.
Telophase II and Cytokinesis
A nuclear envelope forms around each set of chromosomes & the cytoplasm divides.
By looking at a gene set up or a punnet square,a gene that's dominant would be represented by a capital letter and recessive traits are represented by lowercase letters for example brown eyes are considered a dominant trait which can be represented as BB for homozygous, and Bb for heterozygous. Since blue eyes are recessive they would be bb.
