in dogs there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are mated. what are the possible genotypes and phenotypes of their offspring and the percent of chance for each?
Dd x Dd = DD, Dd, Dd, and dd
3:1 genotype
phenotype shows that there is 3 dominant gene for normal hearing while 1 for deafness (two homozygous where 1 is dominant and the other is recessive) and (two heterozygous with normal hearing dominant over deafness recessive)
Producers have less energy available to them. They have to harness the light to produce energy. Their movement is restricted as a result. Tertiary consumers has the highest amount of energy at their disposal.
