How does an individual’s genotype determine its phenotype? The genetic plan determines the physical appearance. If the genotype is Hh (H stands for dominant brown while h stands for recessive blonde), then the individual would have blonde hair.
Is hh homozygous or heterozygous?
Half the possible offspring will be homozygous, HH, and half will be heterozygous, Hh.
Is hh a purebred genotype?
Hint: BB, hh, ZZ, and jj are all examples of purebred genotypes. … Homozygous genotypes have either all dominant alleles (all capital letters) or all recessive alleles (all lowercase letters).
What would the phenotype be for hh?
For Hh, the gametes can carry the H (dominant allele) or the h (recessive allele). For HH, the gametes can only carry H (the dominant allele). Phenotype: All offspring are ultra hot!!! 2.
Is hh dominant or recessive?
A full head of hair is a dominant feature, with the homozygous gene of HH. However, the recessive trait – baldness – can be manifested in an individual with the homozygous recessive gene, or hh.
Is AA homozygous or heterozygous?
Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.
What is the genotype for a purebred dominant?
A homozygous genotype is one in which both alleles are the same, and an organism with a homozygous genotype is said to be true-breeding or purebred. A homozygous dominant genotype is one in which both alleles are dominant.
What is phenotype example?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
