An explanation of these questions along with the correct answer would be greatly appeciated.
Homework Answers
1.Ans. Dominant
because the trait is expressed in every generation, and if it is recessive suppose it is X-linked recessive most males are effected than females and mostly the females are act as carriers. in the above pedigree trait is passed to every generation with equal frequency and both sexes are effected equally so it is Dominant Trait.
2.Ans.C.2/3
in this true breeding strain is crossed in F1 generation we get all Purple stems because Purple is dominant over green.in F2 generation we get 3 Purple stems and 1 Green stem(3:1).
Purple Stems × Green Stems
PP gg
P g
F1 generation Pg (Purple Stems)
Pg × Pg
| P | g | |
| P |
PP (Purple) |
Pg (Purple) |
| g |
Pg (Purple) |
gg (Green) |
in the question they are asking that amoung the Purple F2 what fraction are expected to be heterozygous
so in F2 there are 3 are Purple in that 2 are Heterozygous so the answer is 2/3

QUESTION 3 When first presented with a pedigree, you should initially look for general trends. For example: Are there affected individuals in each generation? Are both males and females equally affected? Are traits from a father or mother passed on to all their children? Or only to their sons or daughters? Based on these general observations, you can usually make a fairly reasonable guess...

For each pedigree below determine the most likely mode of
inheritance and label each individual with a genotype. If you know
they have a dominant phenotype, but don’t know the genotype, then
label them with both possibilities. Please use the alleles A and a
for autosomal modes of inheritance and XA, Xa and Ya for any types
of sex-linkage (note: an “a” is only on the Y if the trait is
Y-linked). Modes of inheritance are autosomal dominant, autosomal
recessive,...

PEDIGREES When a trait follows Mendelian inheritance it is often possible to figure out its dominance state by using a pedigree. Below are four pedigrees for four different traits. They are all autosomal traits (meaning they are not inherited on the X or Y chromosomes). For each trait, determine if it is dominant, recessive or unable to be determined. And explain each answer If it helps your explanation, you may label the symbols with letters Remember squares are males, circles...

The pedigree from Part A is shown below. Fill in the most likely
genotypes of the indicated individuals in the pedigree. Note that a
dominant allele followed by an underscore (_) indicates that either
the dominant or the recessive allele may be present at the second
position. Drag one pink label (for condition A, autosomal
recessive) to each pink target. Drag one blue label (for condition
B, X-linked recessive) to each...

Pedigree below shows the inheritance pattern in the breeding population. a) For each mode of inheritance listed below, indicate whether it is: 1: likely, 2: possible, or 3: impossible. You may make the following simplifying assumptions: 1) disease alleles are rare among animals in the general population; 2) only mothers contribute mitochondria; 1) Autosomal, sex influenced, dominant in males/recessive in...
