Question
In the water buffalo, a mammal, skin color and hair development are influenced by alleles at two gene loci on the X chromosome. Water buffalo females, like all other mammals, have two X chromosomes in their somatic cells. At the skin-color locus, allele B for brown skin, is dominant to allele b, for white skin. At the hair locus, allele H for hairy is dominant to allele h for hairless. A water buffalo rancher has two female buffalos, WB1 and WB2. Each female has a mixture of two types of patches of hair development and skin color. WB1 has two types of patches, hairy with brown skin or hairless with white skin. WB2 has two types of patches, hairless with brown skin or hairy with white skin.
____: what is the linkage arrangement (ie., configuration or phase) of the alleles at the two loci in WB2?
________: what is the genotype of WB1 ?
Explanation / Answer
Q1) trans configuration
As recessive gene of hair and dominant gene of skin color present on one patch and oppostie patch contained possesses dominant gene of hair and recessiven gene of skin color.
Q2).
HHBB or H_B_ in one patch
hhbb in another patch
