In a cross between two true-breeding plants, Parent #1 with yellow, round peas and Parent #2 with green, wrinkled peas, 1. a. What is the genotype of each plant in the cross. What proportion of the F1 progeny will have the same phenotype as Parent #2. b. After you self the F1s, what proportion of the progeny will have the same phenotype as Parent #1. C.

I need these two answered

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.

Paragraph Styles DIHYBRID GENETICS PROBLEMS Name In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cross a homozygous tall, round pea plant with a homozygous short, wrinkled pea plant. Show the genotypes and phenotypes of the F1 offspring, and the probability of each. 1. Genotype of the homozygous tall, round pea plant Genotype of the homozygous short, wrinkled pea plant. Genotypes Phenotypes acer

Is this correct? Urgent..

Please explain question thoroughly with diagrams and concepts. Thank you

( Question 17 of 17 > Attempt 8 A summer squash plant that produces disc-shaped fruit is crossed with a summer squash plant that produces long fruit. All of the F1 have disc-shaped fruit. When the F1 are intercrossed, F2 progeny are produced in the ratio 9/16 disc-shaped fruit, 6/16 spherical fruit, 1/16 long fruit. Give the genotypes of the F2 progeny. Place two genes in each bin to form a complete genotype.
