The woman has a heterozygous genotype for blood type A which corresponds to AO. If the father (man) has a blood type B, he can have the genotype BB or... See full answer below.Become a member and unlock all Study An...
Which phenotypic ratio would be seen in a cross where one gene is involved, it has a completely dominant allele, one parent is homozygous recessive, and the other parent is heterozygous? Explain the answer. If a phenotypic ratio for a single trait ...
Genotypes can be either homozygous or heterozygous. When the two inherited alleles for a given gene are identical, this specific gene is calledhomozygous. Alternatively, when the two genes are different, the gene is said to be heterozygous. Dominant traits require the presence of only one allele ...
An example of co-dominance can be seen in the coat color of cows. In this case, one allele (A) represents black color, and the other allele (B) represents white color. When these alleles are combined in a heterozygous genotype (AB), the resulting phenotype exhibits both black and white...
Is PP genotype or phenotype? There are three available genotypes, PP (homozygous dominant), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white). ...
What is the likelihood of getting a homozygous offspring from a cross between a recessive true breeding strain and a hybrid strain? Would the phenotype for the homozygote be that of the recessive or dominant trait? Calculate the probability of getti...
For example, individuals with a homozygous 32 base pair deletion in CC-chemokine receptor 5 (CCR5, the entry co-receptor for X5 HIV) have greater resistance to HIV than heterozygous indi- viduals109. Another example is that non-secretors of ABO blood groups are refractory to diarrhoea caused...
Impact of genetic background on development of hyperinsulinemia and diabetes in insulin receptor/insulin receptor substrate-1 double heterozygous mice. Diabetes 2003; 52: 1528–1534. 85 Elchebly M, Payette P, Michaliszyn E, Cromlish W, Collins S, Loy AL et al. Increased insulin sensitivity and...
What genotype could the father not have? If the first child has type A blood and his parents are type AB and type O, what is the chance that the second child would have type A blood? What blood types will the children have if their ...
What would be the phenotype of a heterozygous person with sickle cell anemia? If an individual in the family shows a recessive trait but the parents both show the dominant trait, what would be the genotype of each individual? Would an individual with the genotype Aa have a dominant or rec...
