IRISSAK [1]

Two questions have been asked, and responded to

Answer:

For question 1: The statement is true

For question 2: Yes, the two wild roses are of the same population

Explanation:

Population is simply the total number of organisms of the same species LIVING and BREEDING together in a given area.

I) To be considered part of the same population, two of more organisms MUST BE able to mate i.e produce gametes that are viable enough to fuse together and create new offsprings.

2) Yes! Two wild roses separated by a wide road belong to the SAME POPULATION because

- it is still a given area or habitat

- transfer of pollen grains by agents such as wind or insects is possible, thus breeding still occurs.

According to the Punnett square, offspring from these two parents have a ____________ chance of inheriting two b alleles. Indivi

Explanation:

50%; homozygous recessive; phenotype

According to the Punnett square, offspring from these two parents have a 50%chance of inheriting two b alleles. Individuals that inherit two b alleles are homozygous recessive . Inheriting two b alleles confers the phenotype of blue eyes.

Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For instance, co-dominance, both of a gene's alleles are present, and notable in the phenotype.

The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
