Find the mean height of a population of palm trees with the following information: Trees with heights of 140 feet are bred, and the average height of the progeny is 128 feet. The selection response, R, is 70, and the selection differential, S, is 100
In corn plants, a dominant allele (1) inhibits the expression of kernel color, while the recessive
allele (1) promotes the expression of kernel color when homozygous. Another dominant allele, (P),
causes purple kernel color, while the homozygous recessive genotype (pp) causes red kernels.
Assuming that these alleles assort independently, predict the phenotypic ratio of the offspring if
two plants dihybrid for these characteristics are crossed.
There is a lack of dominance in black (B) and white (W) horse coat colours. An offspring
produced from a black horse and a white horse has a blue-roan coat colour (BW). When
the blue-roan coat is closely examined, both black and white hair can be found.
20.
In an ideal horse population exhibiting Hardy-Weinberg equilibrium, 10 out of
every 150 foals have a white coat. Calculate the frequency of the black horse coat
allele in the population.
