Explanation:

1) 72 of their chromosomes would be somatic and only 2 would be gametes. the number is always two as (normally) an organism will have either 2 X chromosomes (female) or an X and Y chromosome (male).

2) without genetic diversity, an entire species of an organism can go extinct from the same thing as none of them would have mutated any defenses and pass them off to their offspring.

Answers

Answer:

unicellular; multicellular

Explanation:

The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be unicellular while those that are made up of multiple cells are said to be multicellular. Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.

If the allele for having dimples is represented with the letter D, what allele combinations can result in having dimples?

Answers

Answer: DD and Dd

Why? Dimples are dominant meaning that if one dimple trait is in allele it will be shown even if there is a recessive trait. So DD and Dd are the answers

A space used in industry or research settings that has a controlled level of contaminants is called a __________.

Answers

Answer:

Clean room.

Explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).

Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.

A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS

Answers

Answer:

Genotypic ratio = 16 WwDd: 0

Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit

Explanation:

This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).

According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:

WWDD - WD, WD, WD, WD

wwdd - wd, wd, wd, wd

Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.

The genotypic ratio is 4 WwDd: 0

The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.

I NEEEDDD HELP PLEASE

Answers

Answer:

the second answer choice

25% red, 50% pink, and 25% white

Explanation:

construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.

RR is red and occurs once so that is a 25% chance (1/4)

RW is pink and it occurs twice so that is 50% (2/4)

WW is white which occurs once and it is another 25% (1/4)

25%
A red flowered Snapdragon(RR) is crossed to white flowered Snapdragon(rr). The F1 individuals are Pink flowered(Rr). When F1 individuals are self crossed, in the F2 generation, 1 plant with red flowers(RR-25%), 2 plants with pink flowers(Rr-50%), 1 plant is with white flowers(rr-25%) are formed. The phenotypic ratio is 1:2:1 and genotypic ration is 1:2:1.
So, the correct option is ‘25%’.

Explanation:

The hypothalamus controls hunger and satiety. Therefore, option (B) is correct.

What is the role of hypothalamus?

The hypothalamus regulates circadian rhythms, appetite, thirst, and body temperature. The study of illnesses and diseases associated to the neuroendocrine system may benefit from using rat hypothalamic neurons.

The arcuate nucleus, or infundibular nucleus in humans, is a region of the hypothalamus that permits peripheral peptides and proteins to cross the blood-brain barrier and interact with its neurons.

What is complimentary DNA?

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

The information molecule is DNA. It contains information needed to create proteins, which are other big molecules.

These instructions are dispersed throughout 46 lengthy structures called chromosomes that are found inside each of your cells. Numerous smaller pieces of DNA, known as genes, make up these chromosomes.

Complementary sequence is a sequence of bases in a nucleic acid that can be combined to generate a double-stranded structure.

For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents for a different DNA nucleotide.

The DNA sequence can be:

DNA molecule 1: TACCGGATGCCAGATCAAATC, complimentary will be ATGGCCTACGGTCTAGTTTAG.DNA molecule 2: TACGGGGGCGTAACCACAACT, complimentary will be ATGCCCCCGCATTGGTGTTGA.DNA molecule 3: TACCTGTTAAGCTACAAAATT, complimentary will be ATGGACAATTCGATGTTTTAA.

phenotypic ratio of 1 brown, 2 spotted and 1 white, is this an example of complete
dominance or incomplete dominance? Explain your answer.
no

Answers

This is an example of incomplete dominance because neither the brown nor the white allele is dominant. Assuming that the genotype for the brown guinea pig is Bb the white guinea pig is Ww there is a 50% possibility that the offspring is mixed colors since the dominant trait isn’t completely able to mask the recessive one.
