Heritability estimates is a portion of phenotypic variation contributed by heredity. Traits in pigs such as ovulation rate and number of piglets produced per year are highly heritable traits. 2. The formula for computing crude protein is equal to the amount of nitrogen multiplied by 6.25. This is based on the fact that ALL protein materials contain 16% nitrogen.  3. Essentiality of a nutrient depends on the factors such as species, age, health, metabolism.  4.The deficiency symptoms of Selenium may be associated

please help with these two problems. They are not hard I just need a better understanding?

TEST goo.g/CUYGKD 2.) A man with type A blood marries a woman with type B blood. Their child has type O blood. What are the genotypes of these three individuals? What genotypes, and in what frequencies, would you expect in future offspring from this marriage? 3. A man has six fingers on each hand and six toes on each foot. His wife and their daughter have the normal number of digits. Remember that extra digits is a dominant trait. What fraction of this couple's children would be expected to have extra digits?

Show me how to do this punnet square problem

I need help with this.   The ABO blood group of the following stains/samples were determined - the results are shown in the table below:   Evidence and Reference Stains Scenario 1 Observed Phenotype Blood from John Douglas B Blood from Bill Brown AB Blood from Betty Brown O Blood from Emma Douglas B Blood from Gemma Douglas B Blood from Bud Douglas O Blood from Bob Douglas O Stains from lounge room wall A Stains from foot prints A Pool of blood on kitchen floor A Stains on door handles AB Stains on porch light switch B Hunting knives B Blood stained clothing - shirt & pants from duffel bag in trunk of car B Stain from driver's side foot well A Smear from steering wheel B Stain from trunk of car A     Scenario 1, ABO Test Results For the samples presented, provide the possible genotype(s) that can result in the observed phenotype for each sample. Who in the family tree could have been the donor of the stain from the trunk of John Douglas's…

Thank you for your help.

Just need help filling out the bottom part.

elp Normal ▾ B IU A - Corn Breeding / Genetic Problem A corn breeder is working with 2 inbred corn plants. He is interested in two traits: High yield (produces lots of corn) and drought tolerance (does not need lots of water). High yield (H) is dominant to low yields (h). Drought tolerance (D) is dominant to drought intolerance (d). M BEE Inbred 1 is true breeding for drought tolerance and low yield (DDhh). Inbred 2 is true breeding for drought intolerance and high yield (ddHH). In the parent cross (P) the corn breeder crossed inbred 1 with inbred 2. The resulting F₁hybrid (DdHh) was heterozygous for drought tolerance and high yields. Phenotypically all the corn needs little water to grow and produces lots of corn. This is the corn that is sold to farmers, planted in the Spring and harvested in the Fall. Explain why the farmer does NOT hold back some of the Fall harvested (F₂) kernels and plant them next Spring. You must show your work. (Hint: As a %, how many of the F2 kernels still…
