Question
Chapter 3, Problem 10P
Summary Introduction
To determine: The progeny of the apical flower and the leaf types.
Introduction: The descendants of a person, animal, or plant offspring are termed as progeny. These organisms are emerging from sexual or asexual reproduction. A child of a parent is pretended to be the progeny.

A male plant with genotype AaBBCcDdee was crossed with one heterozygous for all thegenes. (a) what is the probability of getting a pollen with ABcDe genes? (b) of producing anovum with three dominant and two recessive genes? (c) of getting a progeny with samephenotype as the female parent? (d) of progeny with exactly same genotype as the femaleparent? (e) If instead of the above male, the cross was with one heterozygous for all thegenes, what proportion of the offspring will have three dominant phenotypic traits. (f) willbe genotypically like the parents?
Consider this four-factor cross: Tt Rr yy Aa × Tt RR Yy aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the probability that the first three plantswill have round seeds? What is the easiest way to solve this problem?
if a plant is an auto-tetraploid with the genotype A1A1A2A2, what is the frequenct of offspring with the genotype A1A1A1A1 following self-fertilization of the plant

A cross is carried out between two pure lines of tomato plants, one having regular leaves and red fruit and the other having potato leaves and yellow fruit. The F1 generation all have regular leaves and red fruit. The F1 individuals are then crossed with one another. Complete a Punnett square to determine the expected F2 progeny on the basis of Mendel's Law of Independent Assortment, which states that the alleles for one gene segregate independently of the alleles for other genes during gamete formation.arrow_forwardA white F2 plant is allowed to self-fertilize.
