What is the best blood group?
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there’s a limited supply of the exact matching blood type. That’s because type O negative blood cells don’t have antibodies to A, B or Rh antigens.
How do you find the phenotype in a Punnett square?
What is a phenotype easy definition?
Phenotype
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
What do you understand by phenotype and genotype explain by giving an example?
Genotype can be described as the genetic makeup of an organism. … Phenotype refers to the physical properties of an organism, which can be observed with our eyes. These include the organism’s appearance, development, behavior, height, color of eyes, hairs, etc.
What is the difference between homozygote and heterozygote?
A heterozygote is an individual having two different alleles at a genetic locus; a homozygote is an individual having two copies of the same allele at a locus.
What is a homozygote and heterozygote?
homozygote, an organism with identical pairs of genes (or alleles) for a specific trait. … In a heterozygous organism, or heterozygote, the genes for a specific trait are different.
Is heterozygous a genotype or phenotype?
An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. … Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
What is the genotype of white?
White fur color is the recessive phenotype, with a aa genotype.
What is the genotype for black chickens?
In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.
What is the phenotype of PP?
The combinations PP, Pp, and pP have the same phenotype-purple flowers. This is because each contains at least one dominant allele (P). Only one combination, pp, produces plants that have white flowers.
