Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate

Coprolites are feces of organisms which becomes fossilized excrements that forms some basic components that describe the food that the ogranism ate. Moreover, like other fossils, the appearance of Glossopteridales fossils and coprolites also helped scientists to study so much about species,

Adaptive features of boxwood shrub

adoni [48]

Answer:

Boxwood shrubs are slow-growing plants with dark green glossy leaves. Some varieties have variegated leaves. Leaf shape depends on the variety; some are round while others are elliptical. They provide thick cover because the foliage begins close to the ground and is dense enough to block light.

Ever since Allison vomited all over her boyfriend after she ate a chicken salad sandwich that had been sitting in the sun all da

AlekseyPX

Answer:

the smell or taste of chicken salad

Explanation:

A conditioned stimulus is the one which was previously a neutral stimulus but hen it gets paired with the unconditioned stimulus it leads to a conditioned response.
The learned response which is produced in response to a neutral stimulus is the conditioned response.
In the given condition the smell or taste of a chicken salad causes Allison to feel nauseated and hence, the taste or smell of a chicken salad is the conditioned stimulus which generates a conditioned response which in this case is nausea.

Match the following terms and definitions. 1. alternative form for a specific gene (either dominant or recessive) hybrid 2. can

galben [10]

The answers would be:

1. Allele - alternative form for a specific gene (either dominant or recessive)

2. Dominant - can prevent the allele from being expressed in a pair of genes

3. Genotype - the genes present in an organism

4. Heterozygous - it is a pair of non-identical genes that influence a trait in different ways.

5. Homozygous - a pair of genes that are identical in the way they influence a trait.

6. Hybrid - offspring from a cross between parents; has different phenotypes for a specific trait.

Here's a little bit more on the topic to help you out in the future:

Alleles are variant forms of genes. Each allele is found in a specific location of a chromosome and that location determines the trait that will be expressed.

There are two types of alleles: Dominant alleles and Recessive alleles.

A dominant allele is expressed physically while a recessive allele is the trait that is masked. If both alleles are present, the dominant allele usually masks the recessive allele. This phenomenon is called complete dominance. There are some traits where both alleles are equally expressed, which is called co-dominance.

Genotype is the set of genes present in an organism that is responsible for specific traits. Phenotype on the other hand is the physical expression of the trait, which depends on the genotype of the organism.

Alleles come in pairs, they could either be homozygous or heterozygous.

Homozygous pairs consist of either 2 dominant alleles or 2 recessive alleles. The genotype would look something like this:

2 dominant :RR or 2 recessive: rr

Heterozygous pairs consist of non-identical alleles, or it has one dominant and one recessive allele. So the genotype would look like this:

Rr

Finally, hybrid is the cross-breeding of two different species that are genetically different. There are many examples of hybrid species like the liger and the mule. The resulting off springs express traits that are different than both parents.
