Topic: Penetrance. Petal number is controlled by a single gene in merigonias. The gene has a completely dominant wild type allele F that makes a plant have five petals and a mutant recessive six petal allele(f). However the six petal trait is only 50% penetrant. You do the cross Ff x Ff. What fraction of the progeny do you have the 6 petals? what is the meaning for 50% penetrant.
Make sure to include (genotypic ratios) For part A) make sure to have table or the phenotypic or genotypic ratios 5. In garden peas, green pod (P) is dominant to yellow pod (p) and tall stemmed (T) plants are dominant to short stemmed plants (t). Please give the genotypic and phenotypic ratios from the following crosses. a) Homozygous green pod homozygous tall stemmed plant crossed with a yellow pod (homozygous) short stemmed (homozygous) plant. b) Homozygous green pod homozygous tall stemmed plant crossed with a heterozygous green pod heterozygous tall stemmed plant. c) Heterozygous green pod heterozygous tall stemmed plant crossed with a heterozygous green pod heterozygous tall stemmed plant. d) Heterozygous green pod homozygous tall stemmed plant crossed with a yellow pod (homozygous) homozygous tall stemmed plant. These are dihybrid crosses. 7. In pea plants, flower colour and pollen shape are located on the same chromosome. A plant with purple flowers and…
