The hybrid progeny in the first generation is called as

When alleles of two contrasting characters are present together, one of the character express and the other remains hidden. This is the

The genotypic ratio of a monohybrid cross is

The geometrical device that helps to find out all the possible combinations of male and female gametes is called

Which of the following terms represent a pair of contrasting characters

The crossing of F1 to any one of the parents is called

From a single ear of corn, a farmer planted 200 kernels which produced 140 tall & 40 short plants. The genotypes of these off springs are most likely

In a plant, red fruit (R) is dominant over yellow fruit (r) and tallness (T) is dominant over shortness (t). If a plant with RRTt genotype is crossed with a plant that is rrtt

If two pea plants having red (dominant) coloured flowers with unknown genotypes are crossed, 75% of the flowers are red and 25% are white. The genotypic constitution of the parents having red coloured flowers will be

F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1 : 2 : 1. It represents in case of
