Here is the difference between a climate and a weather that will help explain the given statements. When we say climate, this is the weather condition that exist in an area or a particular region over a LONG PERIOD OF TIME. On the other hand, weather is the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc. This changes often.

Determine the phenotypic ratios of the offspring. 9 yellow-inflated : 3 yellow-constricted : 3 green-inflated: 1 green-constrict

skad [1K]

From a cross between dihybrid individuals, whose diallelic genes code for one trait each, expressing complete dominance, the phenotypic ratio is B) 9 green-inflated : 3 green-constricted : 3 yellow-inflated :1 yellow-constricted.

-------------------------------

Since I do not have the cross, I will assume the cross involves two dihybrid individuals by looking at the options.

So, let us picture the situation,

Two diallelic genes code for one trait each, color and inflated/constricted pods.
G allele is the dominant and codes for green pods
g allele is recessive and codes for yellow pods
I is the dominant allele and codes for inflated pods
i is recessive and codes for constricted pods
These genes are not linked

1st Cross) Two h0m0zyg0us individuals

Parental) GGII x ggii

F1) 100% GgIi

2nd Cross) Selfcross between F1 individuals

Parentals) GgIi x GgIi

Gametes) GI, Gi, gI, gi

GI, Gi, gI, gi

Punnett square) GI Gi gI gi

GI GGII GGIi GgII GgIi

Gi GGIi GGii GgIi Ggii

gI GgII GgIi ggII ggIi

gi GgIi Ggii ggIi ggii

F2) Genotype

1/16 GGII
2/16 GGIi
1/16 GGii
2/16 GgII
4/16 GgIi
2/16 Ggii
1/16 ggII
2/16 ggIi
1/16 ggii

Phenotype

9/16 G-I- ⇒ Green and Inflated
3/16 G-ii ⇒ Green and constricted
3/16 ggI- ⇒ Yellow and inflated
1/16 ggii ⇒ Yellow and constricted

Phenotypic ratio 9:3:3:1

Options

A) 9 yellow-inflated : 3 yellow-constricted : 3 green-inflated: 1 green-constricted ⇒ NOT CORRECT

B) 9 green-inflated : 3 green-constricted : 3 yellow-inflated : 1 yellow-constricted ⇒ CORRECT

C) 9 green-constricted : 3 green-inflated : 3 yellow-constricted : 1 yellow-inflated ⇒ NOT CORRECT

D) 9 yellow-constricted : 3 yellow-inflated : 3 green-constricted : 1 green-inflated ⇒ NOT CORRECT

Three students are arguing about the reason that an apple appears red. Student A claims that it is because an apple absorbs the

marin [14]

Answer:

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. ... For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum.

Define heterozygous and provide and example

valentinak56 [21]

Definition:

Having two different alleles of a particular gene or genes.

(an Allele is a variant form of a gene.)

Simplification:

If the organism has one copy of two different alleles, it is heterozygous.

Eg: T and t

(T for tall and t for short)

Example:

Pea Plants

Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
