Question

Какими признаками будут обладать гибридные томаты полученные в результате опыления растений , имеющие красные плоды и нормальный рост, пыльцой желтоплодных карликовых томатов.Какой результат даст дальнейшее скрещивание таких гибридов?Известно, что красный цвет плодов-доминантный признак, карликовость-рецессивный. Все исходные растения гомозиготны, а гены обоих признаков находятся в разных хромосомах

Answer 1

Все решение написано во вложении. 

 Там где F1 : АаBb - красный , с норм. ростом . ( извиняюсь за ошибку )

Characteristics of Hybrid Tomatoes Resulting from Cross-Pollination

Hybrid tomatoes resulting from cross-pollination between plants with red fruits and normal growth, and pollen from yellow-fruited dwarf tomatoes, will exhibit specific characteristics.

1. Red Fruits: - The hybrid tomatoes will have red fruits, as red color is a dominant trait in tomatoes.

2. Normal Growth: - The hybrid tomatoes will exhibit normal growth patterns, as the plants from which they were cross-pollinated had normal growth.

3. Genetic Composition: - All the parent plants are homozygous, and the genes for both traits (red color and dwarfism) are located on different chromosomes.

Result of Further Crossbreeding of Such Hybrids

When these hybrid tomatoes are further crossbred, the result will depend on the genetic composition and the specific traits being targeted.

1. Red Color Dominance: - The red color trait being dominant means that the majority of the resulting offspring from further crossbreeding will also have red fruits.

2. Dwarfism Recessiveness: - Since dwarfism is a recessive trait, further crossbreeding may result in a mix of dwarf and normal-sized plants, with the potential for some plants to exhibit the dwarf trait.

3. Genetic Variation: - The specific outcomes of further crossbreeding will depend on the genetic makeup of the parent plants and the laws of genetic inheritance.

In summary, the resulting hybrid tomatoes will have red fruits and normal growth, and further crossbreeding may lead to a mix of red-fruited plants with varying growth patterns, influenced by the dominant and recessive traits involved.
