Examine the punnett square below, which represents a cross between a male and a female pear tree. what are the possible genetic variations of offspring in this cross? bb bb bb

The correct answer is -

The possible genetic variations of offspring in this cross would be BB and Bb, which will be produced in the ratio in the ratio 1:1.

The genotype of parents in the cross are- Bb and BB.

When they are crossed with each other, they will produce BB, BB, Bb, Bb offsprings (that can also be filled in the punett square according to the fusion of the gametes shown there)

This indicates that only two genetic variations are produced in the offspring of this cross, which are BB and Bb (in the ratio 1:1).

In other words, there is 50% chance of BB and 50% chance of Bb.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
