Answer:

D. ww

Explanation:

The genotype of short whiskers is recessive.  For a recessive characteristic to appear phenotypically ( this means, this can be seen)    the two alleles present must be recessive

Answer:

D (ww)

Explanation:

This is a cross involving a single gene coding for whisker length in cats. The allele for long whiskers (W) is dominant over the allele for short whiskers (w) i.e. the W allele will mask the expression of w allele in a heterozygous state.

Since long whisker allele (W) is dominant, it means the dominant trait (long whisker) will be expressed if the genotype if a cat is homozygous dominant (WW) or heterozygous (Ww). However, the recessive trait (short whiskers) can only be phenotypically expressed when the cat's genotype is homozygous recessive (ww).

Therefore, if a cross between a Ww (heterozygous) cat and a ww (homozygous recessive) cat produces an offspring with short whiskers, It means that the offspring has a homozygous recessive genotype (ww) since it expresses the recessive trait.

GenaCL600 [577]

Answer:

ZBWCYAX

Explanation:

Equation for the intermediates: Z↔W↔Y↔X

1) B catalyzes the breakdown of Z, therefore inhibiting B leads to the build up of Z.

2) If enzyme C is inactive then the organism will not  receive Y to grow, thus Y is a by-product of C.

3) If A is inhibited then W, Y and Z build except for X, thus it make sense that A catalyzes a reaction that leads to X as a by-product.

4) Inhibiting C leads to the reaction toward making Z and W, thus it catalyzes the breakdown of C directly and Z indirectly.
