Answer:

The correct answer would be homozygous.

There are two types of combination of alleles in an organism:

Homozygous: An organism is said to be homozygous for a gene it carries two identical alleles of the gene. The homozygous can be of two types homozygous recessive (for example, rr, tt, yy) and homozygous dominant (for example, RR, TT, YY).

Heterozygous: An organism is said to be heterozygous if it carries two different types of alleles for the gene. For example, Rr, Tt, Yy. Usually, the phenotype of the organism is the dominant trait.

A population that is isolated in a remote environment is still able to experience genetic variation How could genetic variation

goblinko [34]

A mistake in DNA replication before meiosis produces an organism that is better able to outrun predators.

Explanation:

The genetic variation results from the different alleles of a population. The mutation or mistake in DNA replication would cause gene variants which may be beneficial. The variation in the DNA sequence of genome results in variants in small population.

Genetic variation is the cause of natural selection and eventually, evolution takes place with beneficial traits.

It is mentioned in the question that resulting offspring having received the mutant allele could result in better surviving capabilities or phenotypic traits as they are able to outrun predators.

A purebred purple flowering plant is crossed with a purebred white flowering plant, and they produce offspring that have purple

Colt1911 [192]

Answer:

The purple flower is a dominant trait.

It can be explained with the help of the law of dominance which states that the trait which expresses itself and masks the other in a heterozygous condition is called a dominant trait.

When two purebred parents for a particular trait (like flower color in this case) are crossed, it always results in a heterozygous offspring. The trait which is expressed in the heterozygous condition is said to be a dominant trait.

Like in this case, the offspring had purple flowers. Thus, the purple flower is a dominant trait.

marta [7]

<h2>The correct answer is (C).</h2>

Explanation:

Tendons are the connective tissues that connects a muscle to other body parts, such as bones.

Tendons transfer the mechanical force of muscle contraction to the bones.

Tendons are strong in nature which have a high tensile strength.

Its strong nature help to withstand the stress which is generated by muscular contraction.

Ligament belongs to the fibrous connective tissue which connects bones to other bones.

Ligament are also known as true ligament, fibrous ligament, articular ligament.

Ligaments shows similarity with tendons and fasciae as they are also made up of connective tissue.
