b) the first plant being dwarf or tall
c) the first three plants to be tall
d) to have seven plants, that are tall and four
dwarf
e) that the first plant be tall, and that of the next
four plants, to be tall and the other two dwarf.

E. W. Lindstrom crossed two corn plants with green seedlings and obtained the following progeny: 3583 green seedlings, 853 virescentwhite seedlings, and 260 yellow seedlings .
Q. Is there epistasis among the genes that determine color in the corn seedlings? If so, which gene is epistatic and which is hypostatic?

In the F2 there were a total of 13,923 plants with a continuous variation in heights between the two extremes and with only 3 plants as large as 47 cm high and 5 plants of 11 cm high. a) How many i) genes and ii) how many alleles are involved in determining height in this plant?arrow_forward1) In some species of pea plant, pea colour is determined by one pair of alleles and pea shape by another - the genes are on different chromosomes. A plant grown from a round green pea was self-pollinated. The following numbers of offspring were obtained: 95 green round, 28 white round, 30 green wrinkled, 11 white wrinkled. a) What is the ratio of the phenotypes in the offspring? b) In each pair of alleles, colour and shape, which allele is dominant and which recessive? c) what was the genotype of the parent(s)?

A diploid heterozygous for a null allele and the wild-type allele will be viable. A diploid heterozygous for a null allele and a wild-type allele will be nonviable. A diploid homozygous for a null allele will be nonviable. A null allele would lead to nonviable haploid cells.arrow_forward
