Summary Introduction
To review:
The possible cause for the malformation (six or more limbs) in frogs found in certain ponds of northen united states.
Introduction:
Retinoic acid is a vitamin A derivative which play an important role in specifying the anterior posterior axis and essential for the normal growth and development in chordates. But sometime a compound required for the normal growth and development may cause deleterious effects when present in large or inappropriate quantities. The abnormal limb development in the frogs of northen united states also associated with the increase in retinoic acid in frog limb buds following the frog association with a

Examination of thousands of plants in a certain species revealed a range of pubescence from 60 hairs/cm to the glabrous (non-pubescent) condition. Assume that this variability is controlled by three gene pairs having a cumulative effect. Ignore the environment effect. When entirely pubescent (60 hairs/cm) were crossed to glabrous plants (0 hairs/em), all offsprings in the F, exhibited an intermediate pubescent condition (30 hairs/cm). Several of the Fi plants were selfed and the F2 plants were evaluated for pubescence. a. Assign genotypes to the original plants and the Fi plants. b. What proportion of the F2 progeny would be expected to be: i. Completely pubescent (60 hairs/cm)? Intermediate pubescent (30 hairs/cm*)? With 40 hairs/cm?? Homozygous for the genes involved? ii. iv.arrow_forwardAssessment criteria 1.1 Q1.

The daughter cells produced in mitosis are genetically different from the parent cells, but have the same number of chromosomes, while these are genetically similar in case of meiosis and have fewer chromosomes. B.) The daughter cells produced in mitosis ate genetically similar to the parent cells and have the same chromosomes , while these are genetically different in merosis and have half the number of chromosomes. C.) The daughter cells produced in both cases are genetically similar to the parent cells, but in there are fewer chromosomes . D.) The daughter cells produced in both cases are genetically different but in mitosis , there are fewwer chromosomes in daughter cells 2.)
