If a cross is made between two parental homozygous allele female Red phenotype (RR) cross with male white phenotype (rr) resulting F1 progeny is all red phenotype (Rr), if reciprocate this cross the resulting progeny will be change.
a) Gene expression will be the parental origin dependent
b) uniparental gene contribution and also the expression of the gene is uniparental
c) Gene expression independent over parental origin
d) Gene contribution is biparental but the expression of the gene is uniparental
This prediction concludes that,

Insulin like growth factor in mice, where IgF+ represents tall, IgF- represent dwarf phenotype, if cross between male tall (IgF+/IgF+) with female dwarf (IgF-/IgF-) resulting progeny will shows tall phenotype , while reciprocate this cross resulting progeny shows dwarf phenotype. If resulting these F1 progeny cross each other then what will be the ratio in F2 generation?

The following is a hypothetical pathway responsible for the coat color in Labrador retrievers, The pathway is controlled by two independently assorting genes ‘B’ and ‘E’ encoding enzymes as shown below. Mutant alleles ‘b’ and ‘e’ code for non- functional proteins.

A locus determines the type of pigment produced in the squash, with yellow (Y_) dominant over green (yy). This locus is expressed only in ww plants, which lack the dominant inhibitory allele W. We can assign the genotype ww Y_ to plants that produce yellow squash and the genotype ww yy to plants that produce green squash. The genotypes and their associated phenotypes are:
What will be the correct prediction about these pathway?

The interaction of two loci that determine fruit color in
summer squash, which is commonly found in one of three colors: yellow, white,
or green. When a homozygous plant that produces white squash is crossed with a
homozygous plant that produces green squash and the F1 plants are crossed with
each other, the following results are obtained:
