Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).
Independent grouping of qualities happens amid meiosis in eukaryotes. Meiosis could be a sort of cell division that diminishes the number of chromosomes in a parent cell by half to deliver four regenerative cells called gametes. In people, diploid cells contain 46 chromosomes, with 23 chromosomes acquired from the mother and a moment comparative set of 23 chromosomes acquired from the father. Sets of comparable chromosomes are called homologous chromosomes. Amid meiosis, the sets of homologous chromosome are separated in half to make haploid cells, and this partition, or grouping, of homologous chromosomes is arbitrary. This implies that all of the maternal chromosomes will not be isolated into one cell, whereas the all fatherly chromosomes are isolated into another. Instep, after meiosis happens, each haploid cell contains a blend of qualities from the organism's mother and father.
