Which of the following assertions about the independent assortment of two X-linked recessive traits is true?

In cats, a dominant allele F causes fur to be short, and its recessive allele f produces long fur. Eye color is controlled by an independently assorting gene; the dominant allele G produces green eyes, and the recessive allele g produces blue eyes. When cats from a true-breeding short, green-eyed variety are crossed with cats from a true-breeding long, blue-eyed variety, what would be the genotype of their progeny?

Assume that black short hair (BBSS) is dominant in guinea pigs over white long hair (bbss). Heterozygous black short guinea pigs (BbSs) are produced in the F1 generation when the genotype BBSS crosses with bbss. What will be the phenotypic distribution of the F2 generation's offspring if these F1 hybrids are interbred?

For an independently assorting gene, short hair (S) is dominant over long hair (s) in rabbits, and black skin (B) is dominant over brown skin (b). When the male and female with the heterozygous genotype BbSs from the F1 generation are self-crossed, what is the probability of having the genotype BBSS in the F2 generation?

Assume that in a given plant, T represents the dominant trait for tallness over dwarfism (t) and P represents the dominant trait for the purple flower over the white flower (p). If a pure-breeding plant with the genotype TTPP is crossed with the pure-breeding plant with the genotype ttpp and produced the genotype TtPp, how many gametes are formed by the F1 plants when self-crossed in the F2 generation?

What would be the phenotype ratio of the offspring if a plant with the genotype RRTt is crossed with a plant of genotype rrtt, where R represents the dominant trait for red fruits, r represents the recessive trait for white fruits, T represents the dominant trait for tallness, and t represents the recessive trait for dwarfism?

When a tall pea plant with round seeds (TTRR) was crossed with a dwarf pea plant with wrinkled seeds (ttrr), where T stands for dominant tall and t for recessive dwarf height, and R for dominant round and r for recessive wrinkled seed shape, the results were as follows: The individual F1 populations all possessed tall, round seeds. However, self-pollination among F1 individuals resulted in a phenotypic ratio of  9:3:3:1. This ratio is caused by which of the following principles?

How is the principle of independent assortment of characters demonstrated using pea plants with the traits of tall and dwarf and smooth and wrinkled seeds?
