How many gametes aabbcc

Review problem 3's tutorial if necessary. Possible gametes for each AaBb parent Since each parent has four different combinations of alleles in the gametes, there are sixteen possible combinations for this cross.

Therefore we use a 4 square by 4 square Punnett Square. To determine the fraction of the offspring homozygous for both traits, first determine the genotype of an offspring homozygous for both traits. Which one of the following is an example of polygenic inheritance? Subtopic: Dihybrid Cross Analysis. Test cross involves : 1 crossing between two geneotypes with recessive trait 2 crossing between two F 1 hybrids 3 crossing the F 1 hybrid with a double recessive genotype 4 crossing between two genotypes with dominant trait.

Subtopic: Monohybrid Cross: Further Understanding. If a colourblind woman marries a normal visioned man, their sons wil be : 1 all normal visioned 2 one-half colourblind and one-half normal 3 three-fourths colourblind and one-fourth normal 4 all colourblind. Subtopic: Sex Linked Recessive Inheritance. Cri-du-chat syndrome in humans is caused by the : 1 fertilization of an XX egg by a normal Y-bearing sperm 2 loss of half of the short arm of chromosome 5 3 loss of half of the long arm of chromosome 5 4 trisomy of 21st chromosome.

Subtopic: Recombination Gene Mapping. Sickle cell anaemia has not been eliminated from the African population because : 1 it is controlled by recessive genes b it is not a fatal disease 3 it provides immunity against malaria 4 it is controlled by a dominant genes. Which of the following shows linkage group in coupling phase? Get Android App. Get iOS App.

Photochemical smog pollution does not contain- Environmental Issues. A steroid hormone which regulates glucose metabolism is - Chemical Coordination and Integration. Amino acid sequence, in protein synthesis is decided by the sequence of- Molecular Basis of Inheritance. Golden Rice is a promising transgenic crop. When released for cultivation, it will help in Biotechnology and its Applications.
