In watermelon fruits, the rind can be green or striped, the shape of the fruit is long or round. A homozygous plant with long green fruits is crossed with a homozygous plant with round striped fruits. In F1, the fruits are round green. Determine: 1) which features are dominant; 2) the genotype and phenotype of the offspring from the analyzing crossing of F1 hybrids.
1) Dominant features – striped color and round shape of the fruit, recessive – green color and long shape of the fruit;
2) a) genotypes of offspring from the analyzing crossing of F1 hybrids – AaBb, Aabb, aaBb, aabb in a ratio of 1: 1: 1: 1;
b) the phenotypes of the offspring from the analyzing crossing of F1 hybrids – plants with round striped, round long, green striped and green long fruits in the ratio.
