Speciation<span>. </span>Speciation<span> is the </span>evolutionary process<span> by which biological populations </span>evolve<span> to become distinct species. The biologist Orator F. Cook coined the term '</span>speciation' in 1906 for the splitting of lineages or "cladogenesis", as opposed to "anagenesis" or "phyleticevolution<span>" within lineages.</span>
Answer:
It enters fish through the gills and the female attaches to the tongue, with the male attaching on the gill arches beneath and behind the female. Females are 8–29 millimetres (0.3–1.1 in) long and 4–14 mm (0.16–0.55 in) wide.

Answer:
All Offsprings will have a red flower and tall phenotype with a genotypic ratio of 1 RrTT : 1 RrTt
Explanation:
This is a cross involving two genes; one coding for rose color and the other for height in rose plant. The red allele (R) is dominant over the white allele (r) in the first gene while tallness (T) is dominant over shortness (t) in the second gene.
Based on this, a homozygous red and tall flower will possess a genotype: RRTT while a flower that is white and heterozygous tall will have genotype: rrTt. Hence, each parent's allele will separate into gametes independently of one another according to Mendel's law of independent assortment. The possible gametes combination are:
RRTT- RT, RT, RT, RT
rrTt- rT, rt, rT, rt.
Hence, using a punnet square (see attached image), all offsprings will possess the phenotypic dominant trait i.e. red and tall. The genotypes produced are: RrTT and RrTt in a ratio 1:1
