what is the difference between chromosome and gene?
explain the table in NCERT which differentiates b/w the two, i found both of them to be the same then where is the difference?
Why the people having sickle cell anaemia disorder do not suffer from malaria?
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 axial and terminal position of flower?
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
Explain why law of segregation is also called law of purity of gametes?
A garden pea plant produced axial white flowers . Another of the same species produced terminal violet flowers. Identify the dominant traits.
A garden pea plant produced inflated yellow pod and another plant of the same species produced constricted green pods. Identify the dominant traits . How do we find and explain the answer?
How is the translation of mRNA terminated? Explain.
Who proposed chromosomal theory of inheritance? Point out any 2 similarities in the behavior of chromosomes and genes
what genetics principles could be derived from a monohybrid cross ?
investigatory project on genetics
how to analyse any trait by using pedigree analysis??
WHAT IS PEDIGREE ANALYSIS? DO YOU SUGGEST HOW THIS ANALYSIS IS USEFUL
Why mendel chose only pea plant for his experiments?
short note on sickle cell anemia
please explain the chromosomal theory of inheritance.
what the line "dominance is not an autonomous feature of a gene " means?????????????
What is the difference between gamete and allele ? Explain with example
what is meant by rudimentary ovaries?
Consider the cross AaBbCcDdEe X aaBbccddee. What proportion of the progeny will genotypically resemble the first parent?
A) 1/64 B) 2/64 C)4/16 D)4/64
organism is heterozygous for 4 loci, how many types of gametes can be
What is genome?How many genomes are present in one of our arm cell?
WHAT IS DOWNS SYNDROME ? GIVE ITS SYMPTOMS AND CAUSES
Differentiate between Mendelian disorders & chromosomal disorders. Give two examples of each.
In a plant tallness is dominant over dwarfness and red flower is dominant over white. Starting with the parents work out a dihybrid cross. What is standard dihybrid ratio? Do you think the values would deviate if the two genes in question are interacting with each other?
what are complementary genes and supplementary genes?
ratio of F2 generation in each case?
give reasons for
(I) both strands of DNA are not copied during transcription
(II)transcription and translation in bacteria can be coupled
how would you find the genotype of an organism exhibiting a dominant phenotype trait ?? (1 mark)
what are the benefits of backcross and test cross??
what is the law of paired factors
what is the genetic basis of wrinkled phenotype of pea seed?
Why do sons of a haemophilic father never suffer from this trait?
Name a disorder, give the karyotype and write the symptoms where a human male suffers as a result of an additional X-chromosome.
The human male never passes on the gene for haemophilia to his son .Justify the statement
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
Lesch Nyhan disease is an X-linked recessive disorder that causes neurological disorder in human beings. A survey of 500 males from a Caucasian population revealed that 20 were affected with this disorder. What is the frequency of normal allele in this population?
is mirabilis jalapa & dogflower (snapdragon) is referred the same plant?
expalin reciprocal cross with an example?
how did mendel make sure that the pea plants were true breeding
in birds, is the sperm or the egg responsible for the of the chicks?
