Answer:

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray

Suppose two independently assorting genes are involved in the pathway that determines fruit color in squash. These genes interac

makvit [3.9K]

Answer:

100% yellow fruit color, Yyww.

Explanation:

Available data:

two independently assorting genes

the W allele codes for a dominant white phenotype

w allele codes for a colored squash

The allele Y codes for a dominant yellow phenotype

the allele y codes for a recessive green phenotype

The phenotypes from the first locus will always mask the phenotype produced by the second locus if the dominant allele (W) is present at the first locus. This masking pattern is known as dominant epistasis

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". When the epistatic gene is dominant, the interaction is known as "dominant epistasis".

W suppresses the expression of Y and y, this means that whenever W is present, the fruit is white. If W is not present, the fruit color can be expressed.

So, the proposed cross in the present problem occurs between a green fruited individual and yellow fruited individual, which suggests that W is absent.

Genotype for Green fruit: yyww

Genotype for purebred Yellow fruit: YYww

Cross:

Parental) YYww x yyww

Gametes) Yw Yw Yw Yw yw yw yw yw

Punnet square) Yw Yw Yw Yw

yw Yyww Yyww Yyww Yyww

F1) 100% Yellow fruited plants, Yyww

As these two genes assort independently, we can also represent the cross for each gene by separate, like this:

For w gene:

Parental) ww x ww

Gametes) w w w w

Punnet square) w w

w ww ww

F1) 4/4 or 100% colored-fruits

For Y gene:

Parental) YY x yy

Gametes) Y Y y y

Punnet square) Y Y

y Yy Yy

F1) 4/4 or 100% yellow fruits, Yy.

Klio2033 [76]

The nurse should reassure the patient will receive the best care in keeping with his written directives Cardiac dysrhythmias associated with altered myocardial automaticity, conductivity or contractility can effect cardiac output. Reduced cardiac output increases the risk of ineffective tissue perfusion. If the dysrhythmia is a life-threatening type, encourage the family unit to calmly formulate a plan of action.

Place the following taxa in order of "inclusion of fewest number of species" to "inclusion of most number of species". 1. Domain

aalyn [17]

Answer:

1)Genus 2)Family 3)Order 4)Phylum 5) Domain

Explanation:

Species is a large group of living organisms that can breed freely among themselves, exchange genes and produce offspring.

Taxonomic rank is the group of living organisms that are related to each other and most basic rank is species. The lower the rank the smaller it be and contain most similar organisms.

The higher rank comprises by combining of smaller ranks like in your question the family contain many genus and order contain many families and so on. Thatswhy most higher rank would contain maximum number of species.
