8. An orchid plant with the genotype GgBb is crossed with an orchid plant with the genotype ggBB. - How many different genotypes can be expressed in the offspring? Da) 2 Di) ) 3 4 o 1

To determine the number of different genotypes that can be expressed in the offspring, we need to consider the possible combinations of alleles that can occur.<br /><br />Given the genotypes of the two orchid plants:<br />- Orchid plant 1: GgBb<br />- Orchid plant 2: ggBB<br /><br />We can use a Punnett square to visualize the possible combinations of alleles in the offspring.<br /><br />Punnett square:<br /><br />| | gB | gB |<br />|-------|-----|-----|<br />| GB | GgBb| GgBb|<br />| gb | ggBb| ggBb|<br /><br />From the Punnett square, we can see that there are 2 different genotypes that can be expressed in the offspring:<br />1. GgBb<br />2. ggBb<br /><br />Therefore, the correct answer is:<br />Da) 2
