It is virtually impossible to locate the genetic factors involved in most psychological characteristics because of <u>polygenic inheritance</u>.

Multiple genes, or polygenes, generate features in polygenic inheritance. Numerous diverse phenotypes, or displayed qualities, may be expressed through polygenic traits. When phenotypes were expressed, a variety of inherited qualities are mixed together due to polygenic inheritance, a kind of incomplete dominant inheritance.

The phenotypic, such as the color of one's hair or skin, is produced by polygenes working together. Polygenic traits don't inherit in the same ways as Mendelian traits do. Multifactorial traits will be many polygenic qualities that have been additionally influenced through the environment.

Based on your knowledge of reproduction in bryophytes and ferns, is the presence of flagellated sperm in cycads surprising? Why
Alisiya [41]

Answer:

The correct answer is - All plants share a similar life cycle

Explanation:

The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.

The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.

6. Now consider a homozygous red eyed, curly winged fly with a pink eyed, heterozygous straight winged fly. Predict the offsprin
devlian [24]

Additional information is missing. It is as follows: In fruit flies, the allele for red eyes is dominant over the allele for pink eyes. Straight wings are dominant over curled wings.

Answer:

Genotype = RrSS and RrSs in 1:1 ratio so each has 0.5 probability

Phenotype = All red eyed and straight winged

Explanation:

Given,

Red eyes (R) is dominant over pink eyes (r)

Straight wings (S) is dominant over curled wings (s)

Fly 1 : Homozygous red eyed, curly winged = RRss

Fly 2 : Pink eyed, heterozygous straight winged = rrSs

RRss will produce Rs gametes and rrSs will produce rS and rs gamates.

When fly 1 and fly 2 mate : RRss X rrSs :

          rS         rs

RS   RrSS     RrSs

The genotypic ratio is 1 : 1 ( RrSS : RrSs ) that means that each genotype has 0.5 probability. Both the genotypes though have at least one dominant allele for each gene so the entire progeny will have red eyes and straight wings.

Months after tonya's left index finger was severed in a factory accident, she noticed an increase in the sensitivity of the fing
mel-nik [20]

This is caused by <span>somatosensory cortex area that used to receive input for the index finger which severed and as a result that area is now receiving input from the other nearby fingers casing the sensitivity to increase.
Neurons are the carriers of the feelings, pain, sensitivity etc to <span>somatosensory cortex and the served finger part's sensory feelings are being received by nearby fingers.</span></span>

Define atomic number and mass number – describe how they differ
larisa86 [58]

Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

hope this helps have a great night❤️❤️❤️❤️
