Assuming that fur colour of an animal ranges from dark, intermediates shades, to white. A cross is made between a male (AABBCC) with dark fur colour and a female (aabbcc) with white fur colour. What would be the fur colour of F1 generation?
All intermediate colour
Range of colour shade
All dark colour
All white colour
This scenario describes polygenic inheritance, where a trait is controlled by three or more genes and the effect of each allele is additive. a cross between a homozygous dominant individual (AABBCC - darkest) and a homozygous recessive individual (aabbcc - lightest) produces F1 offspring with the genotype AaBbCc. This genotype contains three dominant alleles and three recessive alleles, resulting in an intermediate phenotype .
