A plant can have either broad leaves (B) or narrow leaves (b). What cross is represented by the Punnett square shown below?
BB. Bb Bb. bb
What does a punett square show?
The chance of a particular trait being inherited. For each trait there are several alleles, some are dominant and others recessive, for example brown eyes are dominant over blue. The recessive phenotype can only have a genotype with both recessive alleles eg. bb The dominant phenotype can have a genotype with both dominant alleles eg. BB or one of each eg. Bb A punnet square shows the likelihood of a phenotype being inherited from given genotypes, alleles etc... BB and Bb makes BB BB Bb Bb All offspring will have the dominant phenotype (BB or Bb) eg. brown eyes Bb and Bb makes BB Bb Bb bb One in four of the offspring will have the recessive phenotype (bb) eg. blue eyes
What are the possible genotypes of a person with a type B blood?
BB or BO
In rabbits the allele for black fur B is dominant over the allele for brown fur b. Calculate the probability of a homozygous dominant (BB) offspring resulting from a cross between two parents with the?
To calculate the probability of a homozygous dominant (BB) offspring from a cross between two rabbits, we need to consider their genotypes. If both parents are heterozygous (Bb), the possible offspring genotypes would be BB, Bb, Bb, and bb, giving a probability of 1 out of 4, or 25%, for a homozygous dominant (BB) offspring. If one parent is homozygous dominant (BB) and the other is heterozygous (Bb), the probability of BB offspring is 1 out of 2, or 50%.
Can people without the blue eye gene have blue eyed children?
There are two types of genes that brown eyed people can have. There is BB, and Bb. The blue eyed gene is bb. If two people are Bb, and they have a child, if the child receives the two bb from each person, then they will have blue eyes.
