If a plant is inherited by complete dominance where homozygous dominant is a red flower color and homozygous recessive is a whit

WITCHER [35]

Answer:

Genotype of parents is Rr

Explanation:

Let the allele for red flower be represented by "R" and the allele for white flower be represented by "r"

Allele for red color is dominant over allele for white color.

Co-dominant causes the expression of characteristics associated with dominant allele only.

Genotype of parents is Rr

Rr * Rr

RR, Rr, Rr, rr

"rr" is white colored flower

"RR and Rr" is red colored flower

Interpret the Punnett square. A Punnett square with four rows and four columns. The first row is labeled big-A, big-B. The secon

Naddika [18.5K]

Answer:

The genotypes shown represent gametes. False

One of the possible offspring genotypes is AABB. True

The parent genotypes are ABAbaBab×ABAbaBab. True

This cross shows two alleles for two traits. True

The gametes are diploid and the offspring are diploid. False

The genotypes shown are correct for a dihybrid cross. True

Explanation:

║ AB ║ Ab ║ aB ║ ab

AB║ABAB ║ ABAb║ABaB║ABab

Ab║ AbAB║ AbAb ║AbaB║Abab

aB║aBAB ║ aBAb ║aBaB║aBab

ab║abAB ║ abAb ║abaB ║abab

Drawing the Punnett square we can deduce that the genotypes shown do not represent gametes because there are more than 2 pairs of chromosomes.

As shown in the second column second row of the Punnett square one of the possible genotypes is AABB, it is distributed different (ABAB) but it is the same possible genotype.

The parents' genotypes are the ones that are written in the first columns and first row, they coincide with the ones in the statement.

A dihybrid cross shows the cross between two genes that have different traits.

The gametes are always haploid and the offspring are diploid because the two gametes come together.

Which emergency condition requires the immediate use of cardiopulmonary resuscitation (cpr)? quizlety

Black_prince [1.1K]

Emergency condition like Myocardial Infarction requires the immediate use of cardiopulmonary resuscitation (cpr).

<h3>What is Myocardial Infarction?</h3>

Myocardial infarction, another name for a heart attack, is an extremely serious condition caused by inadequate blood flow to your heart muscle. Although there are several potential causes, the most frequent one is a blockage in one or more of the arteries leading to your heart. Without blood supply, the damaged heart muscle will start to degenerate. If blood flow isn't quickly restored after a heart attack, there could be permanent cardiac damage and even death.

A heart attack is an emergency that puts your life in danger. If you think you or someone you're with is having a heart attack, dial 911 immediately (or your local emergency services phone number).

Trichomes increase the chances of survival for plants living in areas with infrequent rainfall.

If a plant in a very rainy place had trichomes, it would probably adapt and remove them as time passed as they are unnecessary.
