_____ is the oldest possible age that members of a species can attain, whereas _____ is the number of years the average newborn

tankabanditka [31]

Maximum life span is the oldest possible age that members of a species can attain, whereas average life expectancy is the number of years the average newborn in a particular population group is likely to live.

Every living organisms pass through birth, growth, reproduction, old age, death. this period is called as life span.

<h3>What is death? </h3>

When all life activities are stopped in an individual organisms due to various reasons like ageing, disease, accidents, etc. it is called death.

Also some fully grown living organisms divides physically into two daughters, thus ending its independent existence.

<h3>What is living? </h3>

The objects with specific form and structure exhibits growth, development, reproduction, responsiveness and other unique characteristics of life. it is called living beings.

The living world is wonderful with wide range of living organisms. the earth is populated by various types of plants and animals.

Life is a complex organization of chemical molecules that express itself by chemical reactions leading to specific characteristics like cellular structure, growth, development, reproduction, adaptation, consciousness, death, etc.

The inheritance of eye color in Drosophila is controlled by genes on each of the fly's four chromosome pairs. One eye-color gene

algol [13]

Answer:

F1 Females - all wild type

F1 Males - all wild type

F2 Females - - all wild type

F2 Males - 1/2 wild type, 1/2 vermilion

Explanation:

The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.

Female flies have two X chromosomes, male flies have one X and one Y chromosome.

A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).

The female parent can only produce Xᵛ⁺ gametes.

The male parent can produce either Xᵛ or Y gametes.

When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).

The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.

When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:

Xᵛ⁺Xᵛ⁺ females with wild type eyes
Xᵛ⁺ Y males with wild type eyes
Xᵛ Xᵛ⁺ females with wild type eyes
Xᵛ Y males with vermilion eyes
