The genotypes that indicates a homozygous dominant trait is : B. TT
Homozygous : both alleles must be the same, so it eliminate option A.
Dominant trait : One of the allele must be written in Capital letter, so it eliminate option C.
this leaves option B, as the answer
hope this helps
Answer:
300,000 years ago
Explanation:
Homo sapiens evolved from their early hominid predecessors between 200,000 and 300,000 years ago and developed a capacity for language about 50,000 years ago.
In the case of the gene that determines high cholesterol in the blood, the two alleles express incomplete dominance.
What this means is that the dominant allele is not completely dominant over the recessive allele. If the allele was completely dominant, even one allele would be enough to determine the individual's trait as dominant. But in the case of incomplete dominance between the alleles, the heterozygous individuals that have one dominant and one recessive allele are an ''in between'' phenotype.
