How many of them you expect to be "red"? A. 0 B. 250

Explanation / Answer

25. law of independent assortment,

Here if we are talking about extensive genetic variation, in law of dominant, only dominant allele is expressed and no variation is produced, in the law of segregation alleles segregate (3:1) three dominant and one recessive phenotype is produces. But in law of independent assortment (9:3:3:1) different combination of allelic variation leads to extensive genetic variation in offspring.

26. D.X/Y. Y chromosome is acrocentric which means one arm is long and one arm of chromosome is short. Centromere is not in a middle. Whereas X chromosome is metacentric. Centromere is in the moddle.

27. A. centromere location, homologous chromosome non identical homologous chromosomes have same genes and with same length.

28. B. 250, a monohybrid is result of hybrid between two genes, which has one heterozygous character. A typical monohybrid cross has 3:1 offspring ration.
