Heredity and Ev...

Which of the following statements about natural selection are correct?
(i) Natural selection tends to increase the characters that enhance survival and reproduction.
(ii) Individuals with better adaptive ability will produce more progeny.
(iii) Was considered as a mechanism of evolution by Darwin.

Homologous organs indicate:

When a pure strain of tall plants (TT) with round seeds (RR) is crossed with a pure strain of short plants (tt) with wrinkled seeds (rr), an $$F_1$$ generation is produced. The alleles for short and wrinkled are recessive to those for tall and round, respectively. When these $$F_1$$ plants self-pollinate, what proportion of the $$F_2$$ generation is short with wrinkled seeds?

According to the theory of acquired inheritance which one is correct?

Experiment to prove that synthesis of organic compounds formed the basis of origin of life was performed by :

Darwinism explains all except:

In a dihybrid cross, $$f_2$$ generation offsprings show four different phenotypes, while the genotypes are of .......... types.

A man having the genotype EEFfGgHH can produce P number of genetically different sperms, and a woman of genotype IiLLMmNn can generate Q number of genetically different eggs. Determine the values of P and Q.

In garden pea plant, a pure line with round seeds(RR) is crossed with a pure line having wrinkled seeds (rr). The ratio of round seed plants to wrinkled seed plants in $$F_2$$ generation will be?
