Question

allele encodes a protein that is made in the proper amount and functions normally. A. loss-of-function B. mutant C. wild-type D. gain-of-function E. lethal The presence of a group of antigens that determine blood type is an example of a(n) A. Semi lethal allele B. Sex-linked trait C. Multiple allele system D. Incomplete dominance E. None of above 5, In four-o'clock plants, red flower color is dominant to white flower color. However, heterozygous plants have a pink color. If a pink-flowered plant is crossed with a white flowered plant, what wi phenotypic ratios of their offspring? 6. A. 4 red, pink, 4 white B. All pink C. All white D. V pink, % white E. hred, pink

Explanation / Answer

Answer 1-(c) wild type allele is responsible for production of normal phenotype by nor normal protein synthesis.

2-(c) there are three allele for blood group so called multiple allele system.

3-(d) flower colour of four o'clock plant shows incomplete dominance .on crossing RR× WW= RW( pink) obtained but after cross between RW × WW= RW, RW , WW, WW genotypes are obtained . Thus half are pink and half are white.
