what is the difference between acquired and inherited traits ?
Why evolution should not be equated with "progress" ?
Genotypic ratio of dihybrid cross?
How do Mendel's experiments show that traits are inherited independently??
difference between inherited and acquired trait????
a trait may be inherited, but may not be expressed. justify this statement with the help of a suitable example.
how are the areas of study - evolution and classification - interlinked?
How do mendel's experiment show that traits may be dominant or recessive ?
what are acquired traits? acquired traits are not capable of directing evolution justify bu 3 reasons.
why did mendel choose pea plant for his experiment?
difference between homologous and analogous organ?????
Evolution cannot be equated with progress . Explain
how fossils are formed? how we can determine the age of fossil ?
How is the sex of the child determined in human beings?
What are Mendel's three laws of inheritance?
describe any three ways in which individuals with a particular trait may increase in population?
What are homologous and analogous organs in plant and animals? Please explain in breif with their pictures.
Variation is useful for the survival of species overtime but the variants have unequal change of survival.Explain this statement.
A man with blood group A marries a woman with blood group O and their daughter has blood group O.Is this information enough to tell you which of the traits --blood group A or O is dominant ?Why or Why not ?
What are the advantages and Disadvantages of Variation??
What is natural selection and genetic drift?
How are evolution and classification related?
what is speciation????????????
1) Law of Segregation
2) Law of Dominance
3) Law of Independent Assortment
A basket of vegetables contain carrot, potato, radish and tomato. Which of them represent the correct homologous structures?
a) Carrot and potato
b) Carrot and tomato
c) Radish and carrot
d) Radish and potato
an organic compound 'X' on heating with conc. H2SO4 fors a compound 'Y' which on addition of nickel forms a compound 'Z'.One molecule of compound One molecule of compound 'Z'on combustion forms two molecules of CO2 and three molecules of H2O.identify giving reasons the compound X ,Y, and Z. write a chemical for all the reactions involved.
what is genetic drift and natural selection
in a tobacco plant the male gamete has 24 chromosomes. State the number of chromosomes in 1)egg nucleus 2)zygote 3)endosperm 4)leaf cell. PLEASE GIVE ME EXPLAINATION ALSO!!!!!!!!!!!
what is the importance of DNA copying in reproduction?why is variations beneficial to the species but not necessary to an individual? explain
WHAT IS ANALOGOUS ORGAN IN PLANTS ?EXPLAIN WITH EXAMPLE.
what are homologous organs and anologous organs.? give example? how are they provides evidence in support of evolution??
Only variations that confer an advantage to an individual organism will survive in a population. Do you agree with this statement? Why and why not
what are the significance of reproduction?
give examples of acquired traits and inherited traits and mention the differences between them...
you have a basket of vegetable which contains carrot, potato, tomatto, ginger, radish, sweet potato. select two vegetable that represent currect homologous structure
a) potao and sweet potato
b)carrot and radish
c) potato and carrot
d) sweet potao and tomatto
(a) where are genes located?
(b) what is gene?
(c) what is the nature of genes?
Sweet potato and potato are homologous organs or analogous organs.
kindly explain 1)Genetic Drift, 2)Gene Flow, 3)Natural Selection......How is Blood Group determined in humans????
why are traits acquired during the lifetime of an individual not inherited..
which of these belong to the homologous category...from a basket of fruits and vegetable....(potato , raddish , carrot , and tomato.)
a> potato and carrot
b. carrot and raddish
c. potato and raddish
d.tomato and potato
A study found that children with light-coloured eyes are likely to have parents with light-coloured eyes. On this basis, can we say anything about whether the light eye colour trait is dominant or recessive? Why or why not?
I know this is NCERT ques n its available on meritnation bt i dnt find full n gud ans der so pls help me out n ans of di ques plsss.............
Is there any difference between heredity and inheritance?
A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers. The progeny all bore violet flowers, but almost half of them were short. This suggests that the genetic make-up of the tall parent can be depicted as
Why cannot it be (D) TtWw ? Why is it WW?
What are vestigial organs and give some examples?? Also what are alleles??
Define artificial selection. Explain it with help of example.
give examples of homologous organs in plants..??
