Answer:
Genotype of rough coat boar - Rr
Genotype of soft coat sow mate - rr
Explanation:
Rough coat boar must be heterozygous with one dominant allele (R ) and one recessive allele (r )
Genotype of rough coat boar - Rr
Genotype of soft coat sow mate – rr
Now if these two parents are crossed , the offspring produced are represented in the punnet square below –
R r
r Rr rr
r Rr rr
Thus, 50 % of the offspring’s have rough coat (Rr) and 50 % of the offspring’s have smooth coat.

Answer:
Meiosis produces four genetically different haploid cells.
Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment
Explanation:
Meiosis and Mitosis are two types of cell division that occurs in living organisms. However, Mitosis produces daughter cells that are genetically identical to the parent cell while meiosis produces daughter cells that are genetically different from the parent cell. This accounts for the reason meiosis leads to genetic variation.
The production of genetically different cells by meiosis is as a result of the process of the random orientation of chromosomes during metaphase I of meiosis I. This process is called INDEPENDENT ASSORTMENT. However, crossing over occurs during prophase I of meiosis between non-sister chromatids of homologous chromosomes.
Mitosis and meiosis are processes of cell division. Mitosis results in two identical diploid cells, while meiosis creates four varied haploid cells, due to independent assortment and crossing over, which brings about genetic variation.
Both mitosis and meiosis are indeed processes of cell division that occur in living organisms. The fundamental difference between them is that mitosis produces two genetically identical diploid cells (cells with two complete sets of chromosomes), while meiosis results in four genetically varied haploid cells (cells with one complete set of chromosomes).
In mitosis, the division of the nucleus takes place, with each daughter cell receiving a full complement of chromosomes identical to those of the parent cell. On the other hand, in meiosis, two divisions occur, resulting in four daughter cells with half the number of chromosomes as the parent cell. These cells are further genetically unique, for two reasons: Independent assortment where the pairs of homologous chromosomes line up at the equator of the cell in a random manner, and crossing over, a process during which homologous chromosomes exchange portions of their DNA.
