Answer: Option A

Explanation:

A paraphyletic group can be defined as the group of organism that includes the ancestors but not all of its descendants.

There are three kinds of phylogenetic groups that can be understood by the help of the diagram.

The phylogeny can be defined as the diagram which shows the evolutionary relationship of one organism from another.

Other groups are monophyletic groups, parsimonious et cetera which shows different evolutionary relationship with organisms.

Who is most at risk of spinal cord injury because of preexisting degenerative disorders?

miskamm [114]

Elderly people are most at risk from minor trauma that results in serious spinal cord injury because of preexisting degenerative vertebral disorders. Males are more prone to spinal cord injuries than females but not as a result of preexisting disorder. This may be related to an increased involvement in contact sports or a propensity to participate in high risk activities. Neither females nor infants are at any particular risk for spinal cord injuries.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) f

lord [1]

Answer:

Please find the punnet square to this question as an attachment

F1 generation:

genotype = BW

Phenotype = Erminette offsprings

F2 generation:

genotype = BB (1): BW(2): WW(1)

Phenotype = 1 Black, 2 Erminette, 1White

Explanation:

This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).

According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)

Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:

Genotypic ratio = BB (1): BW(2): WW(1)

Phenotypic ratio = 1 Black, 2 Erminette, 1White
