In pea plant, yellow seeds is dominant over green seeds. If heterozygous plant having yellow seeds crossed with plant having green seeds then what is the ratio of yellow and green plant in $$F_1$$ generation?

Which represents correct hexaploid nature of wheat, representing monosomic, haploid, nullisomic and trisomic respectively?

Mendel studied the inheritance patterns of 12 different pairs of characters of the pea plant. He could ascertain the independent assortment for only 7 of these 12 pairs of characters by repeated experiments. What can be deduced from this?

When a dihybrid cross is fit into a Punnett Square with 16 boxes, the maximum number of different phenotypes available are

Grain colour of wheat is determined by three pairs of polygenes. What proportion of F$$_2$$ progeny will resemble either parents following a cross of AABBCC (dark colour) with aabbcc (light colour)?

A tall pea plant with round seeds (TTRR) is crossed with a dwarf wrinkle seeded plant (ttrr). F$$_1$$ generation has tall plants with round seeds. What is the proportion of dwarf plants with wrinkled seeds in F$$_2$$ generation?

Which pair of features represents polygenic inheritance?

Albinism is an inherited condition caused by a recessive allele a. A is the dominant allele for the normal condition. What are the genotypes of individuals R and S?
