Question

QUESTION 2 Coat color in Labrador retrievers is determined by two alleles at each of two loci Bb and Ee. Dihybrid crosses produce 9:3:4 black:chocolate:yellow offspring. What can be concluded about the B and E alleles with respect to coat color? They are epistatic They are not epistatic They are in the same biochemical pathway o They are in different biochemical pathways

Answer 1

Here the answer of question 2 is - ix They are epistatic Explanation:~ Epifatasista – one gene's alrere masks the phenotype of the other gene's alleles. Four genotypic classes produce fewer than four phenotypes. Recessive Episfasis" when the recessive allere of one genre masks the effects of either altele of the Gecond gene. Dominant Spaistausis'. ~ When the dominant allele of one gene masks of the effects of either alle of the Second jene. Braistasis differ from comprete Dominanen in ferms that here one allele na mash the of her atlere of Game gese of we found Bee coat-color Úsherifance Es Labrador Retrievers Yellow color dog 1 Black color 1 on 208 Blaex dog Here we saw in F, generation we all dog are Faraox color.
