Which one of the following condition in humans is correctly matched with its chromosomal abnormality/linkage?

Which one of the following conditions in humans is correctly matched with its chromosomal abnormality/ linkage?

Haploids are more suitable for mutation studies than the diploids. This is because

Two genes $\mathrm{R}$ and $\mathrm{Y}$ are located very close on the chromosomal linkage map of maize plant. When RRYY and rryy genotypes ore hybridized, the $\mathrm{F}_2$ segregation will show:

A common test to find the genotype of a hybrid is by:

A human male produces sperms with the genotype $A B, A b, a B$, and ab pertaining to two diallelic characters in equal proportions. What is the corresponding genotype of his person'?

In pea plants, yellow seeds are dominant to green. If heterozygous yellow seeded plant is crossed with a green seeded plant, what ratio of yellow and green seeded plants would you expect in $\mathrm{F}_1$ generation?

Inheritances of skin colour on humans is an example of:

Which one of the following is an example of polygenic inheritance?

Cri-du-chat syndrome in humans is caused by the:

In Mendel's experiments with garden pea, round seed shape (RR) was dominant over wrinkled seeds (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy). What are the expected phenotypes in the $\mathrm{F}_2$ generation the cross RRYY $\times$ rryy?

A person showing unpredictable moods. outbursts of emotion, quarrelsome behaviour and conflicts with others is suffering from:

If a colourblind woman marries a normal visioned man, their sons will be:

Which one of the following is the most suitable medium for culture of Drosophila melanogaster?
