Question 5 :
<p>Which of the following is considered as a recessive character of Mendel?</p>

Question 7 :
In Antirrhinum two plants with pink flowers were hybridized.The F1 plants produced red, pink and white flowers in the proportion of 1 red, 2 pink and 1 white. What could be the genotype of the two plants used for hybridization? Red flower colour is determined by RR and white by rr genes?

Question 8 :
<p>Mendel work later formulated into laws of</p><p>I. Linkage</p><p>II. Segregation</p><p>III. Incomplete dominance</p><p>IV. Independent assortment</p><p>Choose the correct option</p>

Question 9 :
<p>During …A… both members of chromosome pair as well as …B… separate and pass to different gametes. Choose the correct option for A and B</p>

Question 11 :
<p>In <i>Mirabilis</i>, a hybrid for red (RR) and white (rr) flower produces pink (Rr) flower. A plant with pink flower is crossed with white flower, the expected phenotypic ratio is </p>

Question 12 :
A geneticist isolates a gene for a specific traits under study, she also isolate the corresponding mRNA. Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA ?

Question 13 :
1 : 2 : 1 phenotypic and genotypic ratio is found in
