Answer: a-Male cones are smaller than female cones.
The cones are the characteristics of the gymnosperms plant species specifically to the Conifers. These plants exhibit naked ovules and the pollination in these cones is aided by the wind pollination. The male cones are smaller than the female cones and grows on the lower branches of the trees whereas the female cones grows on the higher branches. Each bract or scale of the male cone exhibit numerous pollen grains which are blown away by the wind and they pollinate the ovules of the female cones. Each bract or scale of female cone exhibit an ovule at the lower end. Each ovule is fertilized by the pollen to form the seed.
25%,1:3 This is due to the heterozygous condition to produce on homozygous long and one homozygous short then two heterozygous short.ie 1:2:1,but short is dominant and heterozygous short ate taken to be short ,thus modifying the ratio to 1:3,1:3 is 25%:75%.therefore homozygous long is 25%.
