Answer:
<u>4 types </u>of phenotypes with <u>phenotypic ratio 9:3:3:1 </u>will be obtained.
Explanation:
The Punnett square diagram for the cross between mice with genotype BbCc & BbCc is attached.
It is clear from the diagram attached that the <u>phenotypic ratio</u> will be 9:3:3:1
- The following<u> 9 genotypes</u> will show dominant trait for both the characters i.e. characters represented by B & C genes.
BBCC, BBCc, BbCC, BbCc, BBCc, BbCc, BbCC, BbCc, BbCc
- The following <u>3 genotypes</u> will show dominant trait for one character represented by gene B and recessive trait for other character represented by gene C.
BBcc, Bbcc, Bbcc
- The following <u>3 genotypes</u> will show recessive trait for one character represented by gene B and dominant trait for other character represented by gene C.
bbCC, bbCc, bbCc
- The following genotype is the <u>only genotype </u>which will show recessive trait for both the characters represented by gene B & C.
bbcc

Answer:
Independent assortment can be described as the phenomenon through which genes and chromosomes assort independently into gametes, during the process of meiosis. The alleles of a gene assort independently into chromosomes. Due to this phenomenon, variations are produced among parents and offsprings. For example, parents who are carriers of disease can transfer both the disease-causing alleles in offsprings. Due to this, the offspring will have the disease whereas the parents would be normal.
