1. Sex: First look at expected outcomes for determining sex. Complete the Punnett square using XX (female) as one parent and XY (male) as the other parent. 2. What percentage of offspring will be XX females? 3. What percentage of offspring will be males?
Every living species has two types of cells, somatic cells (diploid) which are responsible for regeneration and replication and gametic (haploid) cells which are responsible for reproduction in the body. Haploid cells are those which have half the number of chromosomes than the parent cell (2n). Whereas, diploid cells are those which have the same number of chromosome like their parents (2n)
The chromosomes are the genetic material present in the nucleus of the cell which is a condensed form of double stranded helical DNA (deoxyribonucleic acid) and histone proteins.
The cells have 46 chromosomes (23 pairs) in which, 22 pairs are called autosomes and 23rd pair is the sex chromosomes which determines the sex of the offspring.
The sex chromosome in the male is denoted as XY and female sex chromosome is denoted as XX.
