What percentage of offspring would be expected to have short whiskers from the cross of two long whiskered seals that are heterozygous?

What percentage of offspring would be expected to have short whiskers from the cross of two long whiskered seals that are heterozygous?

0%
a) What percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one that is homozygous dominant and one that is heterozygous? ANSWER: 0%. A homozygous dominant seal would be “WW” (homozygous dominant = 2 CAPITAL letters).

Where would you find the genotypes for the offspring or babies?

To construct a Punnett square, the genotypes of both parents must be known. One parent’s alleles are listed across the top of the table, and the other parent’s alleles are listed down the left hand side. The resulting offspring genotypes are produced at the intersection of the parent’s alleles.

What genotype would cause a seal to have long whiskers?

dominant allele
1. Let’s say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers and the recessive allele (w) codes for short whiskers.

What is the genotype of RR?

The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape. The predicted inheritance pattern of the offspring results in a 1:2:1 ratio of the genotype.

What percentage of the offspring will have a heterozygous genotype?

The Punnett square below makes it clear that at each birth, there will be a 25% chance of you having a normal homozygous (AA) child, a 50% chance of a healthy heterozygous (Aa) carrier child like you and your mate, and a 25% chance of a homozygous recessive (aa) child who probably will eventually die from this …

What percentage of offspring is yellow?

When counting all four possible outcomes, there is a 3 in 4 probability of offspring having the yellow phenotype and a 1 in 4 probability of offspring having the green phenotype.

What are the genotypes of the offspring?

An offspring’s genotype is the result of the combination of genes in the sex cells or gametes (sperm and ova) that came together in its conception. One sex cell came from each parent. Sex cells normally only have one copy of the gene for each trait (e.g., one copy of the Y or G form of the gene in the example above).

What is the genotype of the parents?

Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype. Each parent contributes one allele to each of its offspring. Thus, in this cross, all offspring will have the Bb genotype.

What is genotype BB?

An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb.

What is the genotype of the heterozygous offspring?

​Heterozygous Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.

What is the percentage of offspring that have short whiskers?

percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one that is homozygous dominant and one that is heterozygous? ANSWER: 0%.

Which is dominant allele codes for long whiskers?

Let’s say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers & the recessive allele (w) codes for short whiskers. a) what does the punnet square look like?

Is the parent seal pure long whiskered?

parent seal is pure long-whiskered and the other is short-whiskered, what percent of offspring would have short whiskers? ANSWER: 0%.

Can a red pigeon give its offspring the recessive allele?

  We know that the brown pigeon must give all of its offspring the recessive allele.   Thus, the red parent pigeon in this problem must have a heterozygous genotype for color, or Bb. Now we can record the parent’s genotypes. Grandparent Pigeons –      Red   X Brown                         (Genotypes)              B __      bb
