Natali [406]3 years ago

Answers & explanation:

I - False

A sympatric speciation can occur commonly in both animals and plants. Sympatric speciation events are very common in plants because it is normal for them to develop multiple sets of chromosomes.

II - False

Sympatric speciation occurs without geographic variation. When two populations of the same species live in the same area but there is no crossing between populations, sympatric speciation occurs.

III - True

Sympatric species may indeed lead to the formation of new species. Sympatric speciation is believed to be responsible, for example, for the large number of cichlid fish species found in Lake Victoria on the African continent. According to research, this lake was colonized by only one ancestral species.

In pea plants, purple flowers are dominant to white flowers, and the purple and white alleles are represented with P and p, resp
amm1812

Answer: 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.

Explanation:

Heterozygous means that its genotype has two distinct alleles, i.e. a dominant and a recessive one. So the genotype of the plants is Pp, and each plant has two alleles since<u> they are diploid organisms, which have two copies of each gene. </u>

<u>Each plant produces gametes, which are haploids cells. That is, they only have one copy of each gene (one allele)</u>. So, the gametes produced by Pp have a P or p genotype.  During fertilization, the maternal and paternal gamete are fused to form a diploid zygote where their genotype will have one allele from the father and one from the mother.

By making this monohybrid cross, we cross the gametes of each parent in the punnett square (see picture)

In the offspring, we see one PP genotype (homozygous dominant), two Pp genotypes (heterozygous) and one pp genotype (homozygous recessive). <u>Since we know the P allele is dominant and it codes for purple color, a genotype only needs one P allele to express that phenotype</u>. So Pp and PP organisms are purple, and only pp is white. That means 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.
