If an H is for tall trait which is dominant and h is the recessive trait for short, which of the following cross will result in 1:1 tall: short progeny?

Correct Answer: Hh X hh
The Punett square shows that the cross between Hh and hh produces Hh and hh in the ratio of 1:1. Here Hh will be tall and hh will be short, thus it produces them in 1:1 ratio as well.

You know that H is dominant for height locus and H is recessive. Is the F2 progeny are a mixture of 3:1 dominant: recessive and you pick a dominant plant at random what will be the probability that the F3 will have a mixture of dominant and recessive traits as well?

In a cross between wild type pure breeding recessive and heterozygous dominant trait, if 4 progeny are found to be expressing the dominant phenotype, what will be the expected number of recessive?

In a genetic cross between the genotypes WWXX and wwxx, the following phenotypic distributions were observed among the F2 progeny: WX, 562; wx, 158; Wx, 38; and wX, 42. Likewise, a cross between XXYY and xxyy yielded the following results: XY, 675; xy, 175; Xy, 72; and xY, 78. Similarly, a cross between WWYY and wwyy yielded: WY, 292; wy, 88; Wy, 12; and wY, 8. In all the genotypes, capital letters denote the dominant allele. Assume that the F1 progeny were self-fertilized in all three crosses. Also, double cross-over does not occur in this species. Which of the following is correct?

In bats the progeny with Qq die. If you cross two wild type bats which are homozygous for dominant and recessive form of the trait, what will be the expected ratio of the F1?

Which of the following statements about gene therapy are correct?
P. Affected individuals, but not their progeny, can be cured through germline gene therapy.
Q. Affected individuals, as well as their progeny, can be cured through germline gene therapy.
R. Affected individuals, but not their progeny, can be cured through somatic gene therapy.
S. Affected individuals, as well as their progeny, can be cured through somatic gene therapy.

If a dominant gene A is lost in a deletion, then the recessive gene a will express itself.
This expression of a recessive trait is called

True breeding Drosophila flies with curved wings and dark bodies were mated with true breeding short wings and tan body Drosophila, The F1 progeny was observed to be with curved wings and tan body. The F1 progeny was again allowed to breed and produced flies of the following phenotype, 45 curved wings tan body, 15 short wings tan body, 16 curved wings dark body and, 6 short wings dark body. The mode of inheritance is

By crossing homozygous short purple flowering parent with a heterozygous tall purple flowering parent you get 41 tall progeny. What will be the expected number of short progenies?

If x is the phenotypic ratio of monohybrid cross for trait A and y is the phenotypic ratio of monohybrid cross for trait B, what would be the phenotypic ratio of a dihybrid cross involving traits A and B?

With green pods as a dominant trait over yellow, which of the following crosses will result in all progeny having yellow pods?
