How can a punnett square predict the traits of offsprings
Anna35 [415]

A punnet square predict the traits of offspring genetic crosses and test crosses.

<u>Explanation:</u>

In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.

The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by  genetic crosses. In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.

An important challenge to traditional (pre-1860) ideas about species was the observation that seemingly dissimilar organisms, su
choli [55]

Answer:

these seemingly dissimilar organisms might have evolved from a distant

Explanation:

Evolution deals with history of organism survival on Earth.

The evolutionary biologists makes use of fossils as proves to give light to having a clear view of how species survived in past times.

Before the theory of natural selection by Charles Darwin, Evolutionary Biologists were filled with questions about why the type of skeletal structural specimens collected were equal and different in dissimilar organisms as it does not exhibit the links seen between these species.

The theory of evolution proposed the mechanism of divergent evolution as a solution to these questions.

Therefore, we conclude that "these seemingly dissimilar organisms might have evolved from a distant" is the right answer.

You cross two true-breeding parents (one with yellow seeds and one with green seeds), grow and self-pollinate the F1 generation,
Andru [333]

Answer:

1500

Explanation:

Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.

The total population size of F2 generation = 2000

The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)

Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500
