Question

1. two sets of plants were grown in two containers. the first container has plants with the genotype anlianl, ygr/ygr. the second container has plants with the genotype anl/anl, ygr/ygr. if the plants in the left container are pollinated by the plants in the right container, what will be the phenotype of the offspring plants? purple stem green leaves purple stem yellow leaves green stem green leaves green stem yellow leaves

Explanation:

Step1: Determine gametes

The first container plants (ANL/ANL, ygr/ygr) produce gametes ANL, ygr. The second container plants (anl/anl, YGR/YGR) produce gametes anl, YGR.

Step2: Analyze offspring genotype

When crossed, the offspring genotype is ANL/anl, YGR/ygr. Assuming ANL (purple stem) is dominant over anl (green stem) and YGR (green leaves) is dominant over ygr (yellow leaves). But wait, no—if we consider that maybe in this context, let's re - evaluate. Wait, no, actually, if we assume that ANL gives purple stem (dominant) and anl gives green stem (recessive), YGR gives green leaves (dominant) and ygr gives yellow leaves (recessive). But the cross: ANL/anl (so purple stem, because ANL is dominant) and YGR/ygr. Wait no, hold on, no—wait the first plant has ygr/ygr (yellow leaves, assuming ygr is recessive for yellow) and second has YGR/YGR (green leaves, YGR dominant). But when we cross ygr (from first parent) and YGR (from second parent), the offspring is YGR/ygr. If YGR is dominant for green, but wait no—the first plant has yellow leaves (ygr/ygr) and second has green (YGR/YGR). But if the cross is YGR/ygr, but if in the problem, maybe there's a mis - labeling. Wait no, another approach: assume that ANL is for stem color (dominant purple) and anl (recessive green), ygr is for leaf color (recessive yellow) and YGR (dominant green). But the cross: ANL/anl (so stem is purple, because ANL is dominant) and YGR/ygr. But no—wait the first parent contributes ygr (yellow leaf allele) and second contributes YGR (green leaf allele). If YGR is dominant, but wait the options have “Purple stem green leaves” as an option. But wait no—wait the first plant's leaves are yellow (ygr/ygr) and second's are green (YGR/YGR). The offspring is YGR/ygr. If YGR is dominant, leaves should be green. But wait the first parent's stem is purple (ANL/ANL) and second's stem is green (anl/anl). Offspring stem is ANL/anl (purple). So offspring is purple stem (ANL/anl) and green leaves (YGR/ygr). But the options have “Purple stem green leaves” as an option. But wait maybe there was a typo in the problem's option labeling. Wait no—another check: assume that in the first container, the plant has purple stem (ANL) and yellow leaves (ygr). Second has green stem (anl) and green leaves (YGR). When crossed: ANL/anl (purple stem) and YGR/ygr. If YGR is dominant for green leaves (assuming that in the problem, the second plant's leaves are green due to YGR and first's yellow due to ygr). So offspring has purple stem (ANL/anl) and green leaves (YGR/ygr). But the first option is “Purple stem green leaves”.

Answer:

Purple stem green leaves
