Adominant gene (w) produces wire-haired texture in dogs; its recessive allele (w) produces smooth hair. a group of heterozygous wire-haired individuals are crossed and their f1 progeny are then test-crossed. determine the expected genotypic and phenotypic ratios among the test cross progeny:

Phenotypic ratio=2:2; Genotypic ratio= 2:2.

Explanation: Test cross is the breeding of an individual with Phenotypically recessive individuals.

Heterozygous wire-haired = Ww

Recessive trait= ww

Test crossing result of offspring= Ww Ww ww ww

Genotypic ratio (genetic composition) = 2:2

Phenotypic ratio= 2:2

2 offsprings are wire-haired and 2 Offspring are smooth-haired.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
