Answer:

The introduced species are usually defined as those species that are entirely new to an ecosystem or biodiversity, and are not native to that particular place. They can occur naturally and can also be transported by humans. They are commonly considered as exotic species.

The appearance of these species can cause great harm to the biodiversity. It can cause changes in the food-chain within an ecosystem. They can outnumber the native species. They can also consume all the food present in an ecosystem and can causes changes in the habitat. The process of hybridization can also take place with the native species.

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The al

Lerok [7]

Answer:

The parent's genotypes are:

Ddpp - tall, white parent

ddPp - dwarf, purple parent.

Explanation:

This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.

According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.

Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).
