Let us construct the punnett square first
AB | Ab | aB | ab | |
AB | AABB | AABb | AaBB | AaBb |
Ab | AABb | AAbb | AaBb | Aabb |
aB | AaBB | AaBb | aaBB | aaBb |
ab | AaBb | Aabb | aaBb | aabb |
a) Probability that the offspring will have either the phenotype -aaB or the genotype aabb:
Now looking into punnett square, we can say probability of phenotype -aaB is 3/16 and probability of aabb is 1/16, therefore applying the rule of addition the answer is 3/16 + 1/16 or 1/4 or 0.25
b) Probability that the offspring will have either the genotype -aabb or the genotype AaBb:
Now looking into punnett square, we can say probability of genotype -aabb is 1/16 and probability of AaBb is 4/16, therefore applying the rule of addition the answer is 1/16 +4/16 = 5/16 or 0.3125
c) Probability that the offspring will have either the genotype A-bb or the genotype AAbb:
Now looking into punnett square, we can say probability of phenotype A-bb is 3/16 and probability of AAbb is 1/16, therefore applying the rule of addition the answer is3/16 + 1/16 or 1/4 or 0.25
d) Probability that the offspring will have either the phenotype A-B- or the genotype aabb:
Now looking into punnett square, we can say probability of phenotype A-B- is 9/16 and probability of aabb is 1/16, therefore applying the rule of addition the answer is 9/16 + 1/16 or 10/16 or 0.625

please answer these papers, they are related to each other. thank you! Student name and UNID Class 18 Mendelian Genetics Class 18 Mandalas The gene involved in the disease Sickle Cell Anemia (SCA) is on human chromosome 11. Allele "A" is the normal form of the gene and codes for a part of the protein complex called hemoglobin. Hemoglobin is required for your blood cells to carry oxygen. Allele "a is an abnormal form of the gene. The hemoglobin protein...
answeres are provided. please explain how to do them. :) A small number of type O individuals have the Bombay blood phenotype. Individuals with the Bombay blood phenotype always appear to have type O blood because they are homozygous recessive for the gene, H, which is epistatic to gene I. As long as at least one dominant H alele is present, the ABO blood type associated with the person's ABO genotype will be expressed. Individuals who are homozygous hh always...
1) The alternate forms of a gene for the same trait are known as -A)alleles. B)phenotypes. C)genotypes. D)codominants. E)incomplete dominants. 2) Mendel carried out most of his research with A)livestock -B)pea plants. C)guinea pigs. D)fruit flies. E)bacteria. 3) Which of the following is true according to Mendel's law of segregation? A)Each individual contains two alleles for each trait. B)Fertilization restores the presence of two alleles. C)Alleles separate from each other during gamete formation. D)Each gamete contains one copy of each...
On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...
i need some help with this lab ASAP please! HUMAN GENETICS It to study because of the relatively long life span and the limited number In addition, the number of chromosome pairs (23) increases the possible number of genetic combinations. It is possible, however, to take a sample from human frequency of a trait and the possible ways a given trait is inherited. populations to estimate the Objectives .Investigate the inheritance of some human traits. Estimate the frequency of selected...
