Answer:
Their child will have brown eyes because brown allele is dominant.
Step-by-step explanation:
Eye Color
– Brown eyes B
– Blue eyes b
Purebred individual with brown eyes (BB)
– Homozygous
Purebred individual with blue eyes (bb)
– Homozygous
Hybrid individual with brown eyes (Bb)
– Heterozygous
Eye Color
– Mother is (BB)
– Father is (bb)
Their Genes Are Crossed
– BB x bb
– Since we are looking at only 1 gene, it is called a monohybrid cross.
Law of Segregation
– Alleles for the same trait must be in separate sex cells.
– Mother is (BB) as his diploid genotype
– Father is (bb) as her diploid genotype
Somatic Cells BB bb
Sex cells B B b b
So according to the punnett square.
B b b
Bb Bb
B Bb Bb
Bb shows that the child will have brown eyes as B allele is dominant over b allele.
Bb = Brown
All of the offspring will have brown eyes, but they will be heterozygous
