If the mother is homozygous recessive then it will be ddee
If the cell is heterozygous it will be DdEe
Possible alleles could be DDEE, dDEE, dDeE, ddee, DDee
It is possible to have genotype De because the mother is homozygous recessive so e comes from there.

Practice Using a Punnett Square. Punnett Squares are tools to identify outcomes known genotypes. They can be used to help infer probabilities of genotypes and from a particular cross. of possible crosses between individuals of phenotypes amongst offspring lele forms "A" and "a".

2. You are working with an autotetraploid species and looking at the inheritance of a gene that has two alleles (A and a). You cross a duplex with a nulliplex individual. Predict the genotypes and their ratios (frequencies) of the resulting progeny from this cross. (Assume 2 x 2 segregation and show your work.) a. List the genotypes and frequency of the gametes produced by each plant. Duplex Nulliplex Gamete genotype Frequency Gamete genotype Frequency b. What would be the...

In simple Mendelian inheritance alleles display a simple dominant/recessive relationship. There are many exceptions to Mendelian laws of inheritance. Most genes have more than two allelic forms and do not exhibit simple Mendelian inheritance. The human ABO antigens are an example of a multiple allelic trait. There are three ABO blood group antigens, IA, IB and i. The i allele is recessive to both IA and IB. A person who is homozygous ii has type O blood and does not...

Linkage: Consider three genes, each with two alleles. An individual with genotype AAbbDD is crossed with an individual whose genotype is aaBBdd. What are all the gamete types (gamete genotypes) that their offspring (AaBbDd) can produce? Draw chromosome diagrams if it helps you to answer the question. a. If the three genes are unlinked? b.
