A plant is heterozygous and is designated Bb and produces two kinds of...
Explanation:
When a plant is heterozygous, it means that it has two different alleles for a particular gene, one inherited from each parent. In this case, the plant has one dominant allele (B) and one recessive allele (b).
The plant produces two kinds of gametes, B and b, which means that the two alleles segregate during meiosis to form haploid gametes. Each gamete contains only one allele of the gene.
The probability of a b gamete fertilising a B gamete is 1/2 or 50%. This is because each parent contributes one gamete to the offspring, and each parent has an equal chance of contributing either a B or b gamete.
Similarly, the probability of a b gamete fertilising another b gamete is also 1/2 or 50%. This is because both parents are heterozygous, which means that each parent has a 50% chance of producing a B gamete and a 50% chance of producing a b gamete.
Therefore, the overall probability of a b gamete fertilising either a B or b gamete is 1/2 or 50%.
