Question

Я знаю, задание жесть, но помогите пожалуйста! Чёрный цвет сорта гречихи определяет А ген, а серый цвет — доминантный В ген. А ген— эпистазный В гену, т.е. В ген не функционирует там, где есть А ген. Если в зиготе нет двух доминантных генов, цвет потомства белый. Определите цвета семя растений, имеющих следующие генотипы:а)ааВb б)aabb в) Ааbb г) ААВb д) АаВВ

Answer 1

в)черный

г)черный

д)серый

Объяснение:

вот так вот

Answer 2

The colors of buckwheat seeds based on their genotypes are as follows:

a) ааВb: The genotype ааВb indicates that the plant has one dominant A gene and one dominant B gene. According to the given information, the presence of the A gene determines the black color, while the presence of the B gene determines the gray color. Since both dominant genes are present, the color of the seeds will be black .

б) aabb: The genotype aabb indicates that the plant has two recessive a genes and two recessive b genes. According to the given information, the absence of both dominant genes (A and B) results in white-colored seeds. Therefore, the color of the seeds will be white .

в) Ааbb: The genotype Ааbb indicates that the plant has one dominant A gene and two recessive b genes. Since the A gene is present, the color of the seeds will be black .

г) ААВb: The genotype ААВb indicates that the plant has two dominant A genes and one dominant B gene. As mentioned earlier, the presence of the A gene determines the black color, while the presence of the B gene determines the gray color. Therefore, the color of the seeds will be black .

д) АаВВ: The genotype АаВВ indicates that the plant has one dominant A gene and two dominant B genes. Since both dominant genes are present, the color of the seeds will be black .

Please note that the information provided is based on the given genotype-color relationship.
