Substances known as 'heredity carriers' are

Mendel's findings were first published in the journal titled:

$A$ factor (allele) is dominant if it is expressed in ...............

$A$ human male is heterozygous for autosomal genes '$A$' and '$B$'. He is also hemizygous for the haemophilic gene '$h$'. What percentage of sperms will carry the '$abh$' genotype (in $\%$) (in $\%$)?

In the case of $PTC$ tasters and non-tasters in humans,$T$ represents the dominant allele and $t$ represents the recessive allele. Which of the following genotypes is unable to taste $PTC$?

How many traits of the pea pod were studied by Mendel?
