The presence of a dimple on the cheek is governed by a dominant gene. A couple had already 4 children with dimpled cheeks. What would be the probability of having the next child as another dimpled if both parents are heterozygous for this character? Show a solution using Punnett Square Method.

Starting with a Parental cross P₁ between AA and aa, what is the exptected proportion of homozygous dominants in the F₂ progeny? Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. a b C d e 1/16 1/8 1/4 1/3 1/2

using a Punnett square, what will the offspring look like when the parents are Bb and Bb. B = dominant black hair and b = recessive blue hair. So what percentage of the offspring will have black hair vs blue hair?

If the tobacco plant parents are both heterozygous for color, what are the possible genotypes and phenotypes of their offspring? Complete the Punnett square below. What is the expected phenotypic ratio?

Suppose two parents, a father with the genotype AaBbccDd and a mother with the genotype aaBbCcDd, want to have children. Assume the loci are inherited independently of each other. Enter your answers as the most simplified fractions (e.g. 1/8 instead of 2/16). What proportion of the offspring are expected to have: The same genotype as the father?  The same phenotype as the father?  All dominant phenotypes?  All recessive phenotypes?

In a dihybrid cross (2 sets of alleles, independently assorted) each parent (heterozygous for both traits) can have 4 combinations of alleles in their gametes), so to calculate the odds for inheritance of particular genetic combinations, we must draw out 16 squares. In the case of our purple/yellow and starchy/sweet corn kernels, we can calculate the odds of the possible phenotypes. Purple & starchy: purple & sweet: yellow & starchy: yellow & sweet, can be calculated as O 9:2:2:3 9:3;3;1 O 5:4:4:3

For the following problem: Identify the gametes for each parent, build a Punnett Square of the probability of offspring. Show the resulting genotype ratios and the resulting phenotype ratios. The submission file on Canvas will typically have a multiple-choice component or may be a fill-in-the-blank question related to genotype and/or phenotype outcomes. Be prepared to address all of these details in the questions. a )In Pansy flowers, a gene for follower color is “incompletely dominant”. All flowers resulting from the cross of a homozygous red (R) flowering plant with a homozygous white (r) flowering plant were pink. If a pink-flowering plant is bred with another pink-flowering plant, determine the probable genotype and phenotype ratios of the offspring. b) The ratio of genotypes is ________________ .c) The ratio of phenotypes (red:pink:white) is ______________.

Given the following parental cross: GgAattHhFfYY x GgAaTtHhffyy What would be the probability of have an individual that was homozygous recessive for each trait? Assume independent assortment. O 1/256 O 1/4096 O 1/128 O 1/2048 O 1/512 O 1/64 O 1/1024

A man who has type B blood (Genotype BO) and a woman who has type A blood (Genotype AO)are having children. What are the possible blood types for the children of the couple? Explainyour answer and the probabilities with a Punnett Square.
