What gametes will be produced by a true breeding pea plant with purple axial flowers genotype PPaa )?

What gametes will be produced by a true-breeding pea plant with purple axial flowers genotype PPaa )?

This cross would be between a pure-breeding white axial (ppAA) and pure-breeding purple, terminal (PPaa) plant. The gametes that will be produced are pA and Pa, respectively. B. Thus, for the F1 generation, all are heterozygous, and all would be purple, axial (PpAa) plants.

What would be the genotype for true-breeding purple-flowered pea plants?

The answer is c) dominant. In a true-breeding plant, the genotype is homozygous so we can assume the purple-flowered plants had the genotype PP and…

What alleles do the gametes contain for a true-breeding purple-flower?

Because the P allele is dominant, all of these F1 individuals are expected to have purple flowers. When F1 individuals are allowed to self-fertilize, the P and p alleles segregate during gamete formation to produce both P gametes and p gametes.

What is the genotype of the purple-flowered offspring?

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.

Which of the plants will be true-breeding?

With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue flowers will produce only seeds that will grow into plants that have blue flowers. With true breeding, the trait is passed on to all subsequent generations.

Is TT recessive?

An organism can be either homozygous dominant ( TT ) or homozygous recessive ( tt ). If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero- means different). Phenotype is a way to describe the traits you can see.

What gametes would be produced in a plant that is homozygous dominant for purple flowers?

Explanation: Let us consider a cross between two plants heterozygous for purple flowers. Each plant will produce two types of gametes, i.e. 50% gametes carrying (P) allele and 50 % carrying (p) allele.

What is the genotype of a true-breeding round pea plant?

A true-breeding plant with round seeds would have a genotype of (RR) for that trait and a true-breeding plant with wrinkled seeds would have a genotype of (rr). When allowed to self-pollinate, the true-breeding plant with round seeds would produce only progeny with round seeds.

When Gregor Mendel crossed true-breeding purple flowered plants with true-breeding white flowered plants Why were all the offspring purple?

Which was true of every offspring of this cross? They would be all purple because purple is the dominant trait and it blocks out the white recessive trait. A cross between two pink camellia plants produced the following offspring: 7 plants with red flowers, 7 with white flowers, and 14 with pink flowers.

Why did Gregor Mendel use peas in his experiments?

Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.

Which is dominant allele A or B?

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.

What are the types of gametes that can be produced by an individual with the genotype AaBb?

Predicting the genotype of offspring

There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.

What is the phenotype of a purple flower pea plant quizlet?

If a pea plant has the dominant phenotype of purple flowers, what do you know about its genotype? In pea plants, purple flowers (P) are dominant to white flowers (p). Two heterozygous (Pp) parent plants are crossbred.

What are the possible phenotype of purple pea plant flower offspring if the parents are PP and PP?

P is dominant to p, so offspring with either the PP or Pp genotype will have the purple-flower phenotype. Only offspring with the pp genotype will have the white-flower phenotype.

Are purple flowers dominant or recessive?


Trait Dominant Expression Recessive Expression
Color of flower (P) Purple White
Form of ripe pods (I) Inflated Constricted
Color of unripe pods (G) Green Yellow
