Why the people having sickle cell anaemia disorder do not suffer from malaria?
A woman with O blood group marries a man with AB blood group(1)work out all the possible phenotypes and genotypes of the progeny.(2)discuss the kind of dominance in the parents and the progeny in this case
whatare complementary and supplementary genes?
Inheritance pattern of ABO blood groups in humans show dominance , co - dominance and multiple allelism. Explain each concept with the help of blood group genotypes.
two heterozygous parents are crossed.If the three loci are linked completely what would be genotypic ratio in F1 generation for a trihybrid cross?
what non parental gene combination?????
how to calculate the genotypic ratio for F3 and F4 generations for a monohybrid cross?
what is the meaning of true breeding pea lines
in a pea plant,smooth seed coats is dominant over wrinkled seed coat. what will be the expected ratio of phenotypes of the offspring in a cross between-
1.heterozygous smooth and heterozygous smooth
2.heterozygous smooth and heterozygous wrinkled
3.heterozygous smooth and homozygous smooth
phenotype of plant that had a genotype Tt
what is the axial and terminal position of flower?
Let us assume in a given plant the genotype symbol "Y" stands for dominant yellow seed colour and "y" for recessive green seeds colour symbol "R" for round seed shape and "r" for wrinkled seeds. Two homozygous parents (plants) with genotypes "RRYY" and "rryy" are crossed and their F1 generation progeny is then selfed. What shall be the
a) Phenotype of F1 progeny
b) Genotype of F1 progeny
c) Gemete genotype of F1 progeny
d) Phenotypic ratio of F2 population
e) Phenotypic ratio of yellow seed to green and round seed to wrinkled seed in F2 population.
Explain why law of segregation is also called law of purity of gametes?
In a linear chromosome, map distances between four loci are as follows: a-b-10, b-c-4, a-d-3, a-c-6. the expected cross over frequency between c and d is-
c) either 3%or 9%
d)4% to 12%
plz provide the solution
