TOPIC: Variations in Gene Expression In a cross involving polygenic inheritance, three (3) gene pairs control plant height. The shortest and tallest plants are 12 cm and 24 cm, respectively. What height should all F1s display if  the shortest and tallest plants were crossed, assuming environmental factors are the same

Problem: A homozygous tall, homozygous white flower plant crosses with a homozygous short, homozygous purple flower plant. We know that the purple and tall flowers are the dominant traits.  Show your work.   What are the phenotypes of the offspring?

Please , if you don’t know the answer just don’t solve it , I don’t want from google or from websites .

CRCR (red flowers); CRCW (pink flowers); CWCW (white flowers); F (full leaves) > f (slender leaves); H (heat tolerant) > h (vulnerable to heat) G*G? (green leaves); GʻG? (green and yellow leaves); G?G² (yellow leaves) CRCR Ff Hh G1G1 x CRCW Ff hh GʻG? Box 1: Which trait displays incomplete dominance? Box 2: What is the PHENOTYPE of the second parent in the cross? Box 3: What is the probability of having an offspring which is completely HETEROZYGOUS? Show your work by listing the fractions and how you would determine the answer (add, subtract, divide, multiply, etc).

Please show proper computation and explanation for me to understand it better. Thank youuuuu

Can you show me the cross and how to get the answers

Topic: Trihybrid Cross, Height in merigonias is determined by three unlinked genes that act additively. Each has two alleles, one compltely dominant allele(A,B or C) that makes plants taller and one recessive allele that makes plants shorter. Do the corss AaBbCc X AaBbCc. The F1 progenty: 27/64 will be as tall as the parents; 37/64 will be shorter than the parents. Pls explain it with more details. thanks

Hello! I am a 7th grade science teacher. I have 16 students, and I was wondering if this app was good enough to get the premium package for my students. If you solve these questions below correctly, I will buy the premium package for my 16 students. (Picture below) Important: Read the box. Answer the question given. Explain your answer choice. (Give 1-2 (7th grade science info) good sentences explaining why you picked your answer.)

Name Period into the genetics problem. Genetics Worksheet # 2 1. In pea plants, smooth peas (S) are dominant to wrinkled peas (s). Work the following crosses. a. homozygous dominant x recessive Genotypes: Phenotypes: Genotypic ratio: Phenotypic ratio: b. heterozygous x heterozygous Genotypes: Phenotypes: Genotypic ratio: Phenotypic ratio: 2, A man and his wife are both heterozygous for brown eyes (B). They have six children all of whom have blue eyes> How can this happen? List the genotypes of the parents and the children. Show the Punnett square. Parents: Kids: What is the chance that the next child will have blue eyes?

Fruit weight is controlled by 4 gene pairs. The homozygous dominant weights 200 g while the homozygous recessive weighs 80 g. Assume that the alleles have equal contribution and have cumulative effects. The F1 and F2 of the two parents below were studied.  Parent 1                                               Parent 2 B1B1B2B2B3B3b4b4             x             b1b1b2b2b3b3B4B4 Provide the genotype and phenotype of the F1.

Given : The given plant is triploid.  Symbol  For purple = P  For yellow seed = Y  For round seed = R  Answer 1. The Probability of PpYyRr = 8/64 = 1/8  2. The  Probability of PPyyRr = 4/64 = 1/16  3. Probability of at least exhibiting wrinkled seeds = 32/64 = 1/2  4. Probability of at least exhibiting purple flowers = 48/64 = 6/8 = 3/4 QUESTION: Answer the remaining question (5, 6, 7)

What are the possible genotype and phenotype of offspring if one pf the parent is heterozygous tall and the other parent is homozygous short Legend  T- tall pea plant  t- short pea plant Question  1. What is the genotypic ratio 2. What are the possible phenotypes of the offspring? 3. What is the phenotypic ratio 4. What is the percentage of having the tall trait.

Y = yellow, y = green; R = round seed, r = wrinkled seed Dihybrid cross: If you mate YyRr x YyRr then what proportion of offspring will be green and wrinkled? 6/16 3/16 O 1/16 O 9/16

Fruit weight is controlled by 4 gene pairs. The homozygous dominant weighs 200 g while the homozygous recessive weighs 80 g. Assume that the alleles have equal contribution and have cumulative effects. The F1 and F2 of the two parents below were studied. Parent 1 - D1D1D2D2D3D3d4d4    x    Parent 2 - d1d1d2d2d3d3D4D4   Compute for the contribution of the dominant allele. Compute for the fruit weight of parental 1 and parental 2.

Can you show the cross on how to get the answers? What is the ratio that is expected with independent assortment? Can you explain anything else related to it ? Nonindependent assortment

What is the possible genotype, or genotypes, of the 95 cm class in the F2? c. What is the possible genotype, or genotypes, of the 95 cm class in the F2?

You are planting a cherry orchard with two rows of female fruiting trees. Below is a diagram of their location, and three empty plots where you could plant male pollen trees. Left Plot S₁S₁ Left S₁ S₂ Middle Middle Plot S₁S3 Middle S₂S3 S₂S3 S₂S3 Based on the S genotype of the above female trees, where would you place male pollen trees with the following genotypes to maximise fertilisation? S₂S₂ Middle S₂S3 Right to S3 S3 Middle = S₁S₁ S₁S₁ S₁S₁ Right Plot

Purple Stem A All seedlings are 72 hours old. Standard Height R seed coat Green Stem a Purple Stem Standard Non-Purple Stem Standard (anl/anl, ROS/ROS) Purple Stem Rosette-Dwarf Non-Purple Stem Rosette-Dwarf Dwarf Height r (ANLIANL, ROS/ROS) (ANLIANL, ros/ros) (anl/anl, ros/ros) Cross a heterozygous (for color only!) purple stem standard (homozygous for height) with a green stem dwarf. What are the parental genotypes? What % is each phenotype in the offspring?

Which trait is dominant for Stem Length ?

Figure shows the first experimental results that indicated linkagebetween two different genes. Conduct a chi square analysis toconfirm that the genes are really linked and the data could not beexplained by independent assortment.
