What is the phenotype of the offspring if one parent is BB and the other is BB?

What is the phenotype of the offspring if one parent is BB and the other is BB?

If the female parent has the genotype BB, all of the offspring will have brown bodies (Figure 9, Outcome 1). If the female parent has the genotype Bb, 50% of the offspring will have brown bodies and 50% of the offspring will have black bodies (Figure 9, Outcome 2).

When a genotype of an offspring is BB it is said to be what?

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 are the chances (%) of an offspring having a BB genotype?

6. Mendel carried out a dihybrid cross to examine the inheritance of the characteristics for seed color and seed shape. The dominant allele for yellow seed color is Y, and the recessive allele for green color is y. The dominant allele for round seeds is R, and the recessive allele for a wrinkled shape is r.

When a genotype has 2 of the same allele ex BB or BB?

homozygous
An individual that contains two copies of the same allele for a specific gene is homozygous. An individual that contains two different alleles of a gene is heterozygous. A cow that has two alleles for a red coat is homozygous (bb).

What does BB mean on a Punnett square?

homozygous dominant
BB is called homozygous dominant. Both genes are the same and dominant. The dominant trait is expressed. Bb is called heterozygous. The organism has a dominant gene and a recessive gene.

Which of the following describes an organism that has the genotype BB?

Inheritance

Question	Answer
Which of the following describes an organism that has the genotype Bb?	Heterozygous
Mendel’s law of segregation states that during meiosis, the factors that control each trait separate, and only___from each pair is/are passed to the offspring.	one chromosome

When a genotype is depicted as BB What phenotype would it express?

Predicting Offspring Phenotypes Only offspring with the bb genotype will have the white-flower phenotype. Therefore, in this cross, you would expect three out of four (75 percent) of the offspring to have purple flowers and one out of four (25 percent) to have white flowers.

What does BB mean in Punnett square?

How is it possible that individuals with two different genotypes can have the same phenotype?

Mandira P. Same phenotype but different genotype is possible due to presence of dominant allele. A person can have a dominant allele on both the homologous chromosomes (i.e. in double dose) while another person may have single dominant allele and a corresponding recessive allele.

When geneticists look at genotype What are they really studying?

When geneticists look at genotype, what are they really studying? Genotype represents the genetic information, or DNA sequence, of an individual organism.

What is the probability of getting offspring that is BB?

Using the Punnett square, you can see that the probability of the Bb genotype is 1 / 2 1/2 1/2 .

How many offspring have the genotype BB in a cross?

In the cross shown in Figure above, you can see that one out of four offspring (25 percent) has the genotype BB, one out of four (25 percent) has the genotype bb, and two out of four (50 percent) have the genotype Bb. These percents of genotypes are what you would expect in any cross between two heterozygous parents.

What does B stand for in a genotype?

With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. 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.

Which is the physical appearance of a genotype?

The physical appearance of the genotype is called the phenotype. For example, children with the genotypes ‘BB’ and ‘Bb’ have brown-eye phenotypes, whereas a child with two blue-eye alleles and the genotype ‘bb’ has blue eyes and a blue-eye phenotype.

Which is the dominant genotype for the purple flower?

You can predict the percents of phenotypes in the offspring of this cross from their genotypes. B is dominant to b, so offspring with either the BB or Bb genotype will have the purple-flower phenotype. Only offspring with the bb genotype will have the white-flower phenotype.
