Answer #1

10A. option C

If two plants (RrTt X RrTt ) are crossed;

The expected phenotype are: i. ROUND and TALL

                                                ii. ROUND   and dwarf

                                               iii. wrinkle   and TALL

                                               iv. wrinkle   and dwarf.

Phenotypic ration:   9:3:3:1.

11A. option d

Cross between : carrier colour blind X normal brown eyes

                             X XC                             X        XY                             PARENTS

                          

                                X XC    X    Y GAMETS

ON FUSION: XX       XY     XCX      XC Y

XX- 25% brown eyes female

XY-25% brown eyes male

XCX -25% carrier female

XCY - 25% colour blind and blue eye male

    Green-weakness partial color blindness, or deuteranomaly, is a sex-linked recessive trait. The green-weakness allele, g, is recessive to the allele for normal color vision, G. Another form of abnormal vision is total color blindness which is due to an autosomal gene, t, which is recessive to its counterpart allele, T, for normal vision. A man with a normal phenotype marries a woman with green-weakness partial color blindness. Both individuals are heterozygous for autosomal color blindness. What phenotypes and phenotypic frequencies...

    the fruit fly, Drosophila melanogaster, an allele (v) of the gene vermillion gives flies purple eyes and is recessive to the wildtype red eye color (v+). An allele y of the yellow gene, gives flies a yellow body color compared to the dominant brown body color (yt). A heterozygous females for the two different mutations is test-crossed with mutant (i.e., homozygous recessive) males. The phenotypes of the progeny of this cross and their corresponding numbers are given below Yellow body,...
